    Senior Expert Access/Excel/VBA/SQL Server Developer/Dot.Net Web/MVC/EF/Azure, Troubleshooter, Optimizer, UI Enhancements, etc... I have 34+ years of experience working with Access, Excel, and then integrating them into harmonious fluid applications, whether it be for the Desktop, or on a WAN. I have developed using every version of Microsoft Office and SQL Server since inception. I specialize in Finance and Manufacturing, including CRM, Inventory and Work Order Management, Job Costing, AR, AP, Purchasing and Sales Forecast Automation, etc. I feel those environments are structurally synonymous with most any other scenario. My current experience involves Loan Origination and Servicing. Working in Finance and Manufacturing, I could not afford to make mistakes. My work ethic developed beginning with my father and being in the Military, in the field of Aviation, where a tiny mistake could cost lives. I am detail oriented with an eye for efficient user friendly complete, from the ground up, to the most custom application imaginable. I have proven complex methods that are far more efficient than the conventional developer, regardless of how well they score on a test; I am the person that goes the extra mile(s) to adhere to the rules of development while maintaining a fluid user friendly interface. I develop from the ground up or customize pre-existing systems. Whether I am developing in Access or Excel, I always structure the data for easy possible future migration, regardless of the interface. An interface can be easily replicated, but carelessly stored data can be very costly. My interfaces are fluid and user friendly. They utilize as much as the available functionality permits, by using Drop-down and List Boxes, and applying Event Code to link to related data without having to return to a menu or dashboard. I am extremely fluent in VBA, using various Object Models, i.e. Access, Excel, DAO, ADO, SQL, Class Modules, SQL Server T-SQL, Stored Procedures and Custom Functions and Triggers, SSMS, SSRS, and SSIS, etc. I write code that a lay person can understand. Where this is not possible, I comment the purpose and flow of the Code. I do not implement limitations, as a lot of developers do, that force the Client to always call on the developer every time a little change is needed. I develop in such a way that considers future expansion. The only time I would ever need to be called upon is to implement new functionality. I prefer to teach Clients the basics so that they can make the subtle physical design changes to the interface that they want, without destroying the integrity of the system. Because I follow the rules of development, the system is straight forward and easily understood.

    I've been making software on the web (mobile, too!) since age 10, first teaching myself Javascript, Visual Basic, PHP, & Objective-C... actively learning how to create things in harmony with technology. I wanted to bring the imagination into the physical world. So now, I build the stuff dreams :). I was a part of a team of hackers in the 90’s building out the next AOL Instant Messenger, developed/designed a massive $500+ million fintech live trading web app, architected a successful $100+ million real estate CRM platform for a startup, built live streaming services with drone integrations for the Pentagon, and have collaborated with some of the best minds in tech over the past decade. I'm a polyglot programmer, fluent in almost every programming language. I really enjoy every aspect of engineering systems. I've seen & worked with almost every environment you can think of, and written in pretty much everything except C/C#/C++. I began programming & selling websites as a teenager before a lot of modern day programming languages even existed. When I'm not spending time with software, you can find me oil painting in techniques developed by Italian Renaissance Masters, making digital crypto-artwork, and sharing some of my life and work through weekly newsletters & videos: an online series focused primarily on wellness, artwork, & business- highlighting what it's like to be a business owner, artist, developer, and wellness activist in today's digital world, while building community at it's core.

    Hello! ...really appreciate you taking the time to check out my profile. Whether it's an issue you need to resolve or you're looking to build something new and exciting, there's a strong probability that I can help. Over the last 20+ years, I have been a: -- Startup founder, as CTO, where I developed prototypes that were eventually backed by angel investors -- Member of engineering teams in venture-backed high-growth businesses In both cases, I've had to play many roles. Including having to: -- Surface and clarify requirements -- Keep projects in scope -- Tackle new technologies -- Work quickly to deliver features I've got the rare experience that combines technical skills with business acumen. The result is project outcomes that help you achieve your short and long-term business goals. I'm focused on helping Upwork clients to: - Build prototypes or Minimum Viable Products (MVP) for the new start-ups - Automate custom trading strategies for traditional and crypto markets I'm fluent in agile software development both as a participant and as a scrum/sprint owner where the goal is to be clear on expectations and to develop solutions iteratively through collaboration. ------------------------------------------------------------------------------------------------------ "Tim is the kind of guy you want to work with. Tim worked with me for several years to see our company site through several incarnations. I would present him with our challenges and he'd find a technological solution to suit our needs. On top of those skills, Tim worked quickly and efficiently, and within budget. I highly recommend working with Tim" - Roger, freelance client "Tim has an impressive ability to turn a vision into a strategy delivered with focus and determination. His empathy, thoughtfulness, diligence, and skill make him someone who can find the things that really matter and do them well. He instils those qualities in those around him by his example, and he takes every chance to listen to feedback, to share his own mountain of expertise, and to build and ship reliable systems." - Jack, former employee "Tim is a motivated, hardworking software engineer, and was very well-liked across the business for his excellent communication and supportiveness." - Wes, former boss "Tim's comprehensive skill set enables him to discover and resolve complex problems while communicating the technical details seamlessly with the rest of the business." - George, former colleague "Tim is very professional, organised, and has the rare combination of technical leadership combined with a strong sense of how to manage technical projects and larger teams." - Martin, former employee "Tim is an executer and strategic thinker with impressive communication skills, but the most remarkable thing I find about Tim is how naturally personable he is." - Andy, former employee "Tim's expertise is pretty damn fascinating, project management comes naturally but most of all emotional intelligence comes high on the agenda." - Justine, former employee "Tim is seriously impressive individual with a great understanding of technology and his ability to communicate at all levels is first class. He has a natural ability to analyse complex problems and present various solutions and recommendations based sound logic, which is a clear indication of his high level thinking." - Matt H, former colleague "Tim has extremely advanced technical communications skills, and possesses the rare ability to grasp the strategic essence of a project, understanding both the commerciality factors and the technical requirements." - Matt C, former colleague ------------------------------------------------------------------------------------------------------ I'm eager to get started on your project.

    Hi, my name is Fedor, I am from Ukraine, now relocated and work from safe place + help other refugees. 💻 I am Senior web developer with more than 5 years experience for commercial projects. I specialize on Angular coding, and developing Shopify stores. ⚡️⚡️⚡️What clients say about me⚡️⚡️⚡️ 'Fedor is amazing! I've worked with other offshore developers before and have had disappointing experiences with the quality of their work and poor communication skills. Fedor is a breath of fresh air! His work is impeccable, he has a critical eye for detail, and clean design aesthetics — exactly the talent I've been looking for! I find Fedor highly responsive, polite, ethical, and an overall pleasure to work with. He has made all the difference to my business, enabling me to offer even a wider range of services — with confidence! Fedor would be an asset to any organization. Highly recommend!' ⭐⭐⭐⭐⭐ Advantages working with me: 💫 high level of proficiency in my tech stack 💫 high code quality with comments 💫 quick communication and turnarounds 💫 I am self managed - you don't need to do micro-management 💫 very reliable Also I produce a good quality code, which is well structured and optimized by the way. And I leave comments at the code, not much but enough to track the idea of what is going on there. I always test my code, so there are always pretty little number of bugs in my works. Out of work I am also a nice guys with a good sense of humor. I like watching films and have fun spending time with my friends. Also I like reading books and listening to the music.

    Building a SaaS startup requires a different approach from enterprise applications. What's missing from the equation is product and customer thinking. While most developers focus on engineering, I focus on how what I'm building benefits the customer. Since 2016, I had the chance to work with more than a dozen startups, including: ➡️ Flashpage, a modern classified ads platform with a sophisticated algorithm, exited to eBay for $3.6 million ➡️ GloriaFood, a restaurant management system with 25,000 restaurants, exited to Oracle for $100+ million ➡️ Rio Stream, an all-in-one platform for gaming streamers to build communities and cross-stream their content, raised $300,000 Seed round, then a $10 million Series A only 11 months later ➡️ Upvoty, a feedback collection tool with $50,000 MRR, founded by solopreneur Mike Strives ➡️ CountdownTimer.ai, a product that allows you to create evergreen timers, achieved 2.8x LTV:CAC ratio and recently crossed $1,000 MRR These founders trusted me to either handle the whole design & development process alone or organize a team and lead them through it with specific targets to hit. And I got them results. Although I cannot help everybody, we may be a great fit if you're thinking: 🤔 “I understand that high quality work is not cheap” 🤔 “I want to ensure my SaaS gets released FAST and it WILL WORK” 😡 “The last freelancer ghosted me and I lost my opportunity - I don't EVER want that experience again” 🤔 “We're looking to scale now that we've validated our SaaS startup” 😡 “The mess the previous freelancer made is forcing us to get someone else to rebuild everything” ⭐ Here's what I can bring to your project ⭐ ✅ Extensive experience with startups, being a founder myself ✅ Peeling your SaaS idea onion until we find the root of your value prop ✅ Optimization techniques for efficiently solving bottlenecks in your SaaS ✅ Scalable solutions for use cases that require high availability and throughput ✅ Focusing on customer needs instead of programming for the sake of writing code ✅ Someone who cares about helping you succeed and bringing value to your business ✅ Advanced understanding of software architectures and what works best for your project When building a SaaS, it's not about the code, but customers do care about their experience. After all, there are so many alternatives nowadays. Cheap freelancers don't care about either and you end up paying with money, time, and lost opportunities. ⭐ Why you should choose me over others ⭐ ✅ Trust: I focus on providing value to all of my clients and am always transparent about my processes ✅ WOW Factor: this is core to my work. I strive to give more than what I receive to ultimately make you happy about working with me and choosing to hire me again ✅ Responsiveness: real-time project dashboard and direct lines of communication to get in touch with me ASAP ✅ Problem-solver: I never give up until I find a good solution. I'm not a coder. I'm a problem-solver. ✅ Genuine: I'm rooting for your success. It makes both human and business sense - knowing I've helped you succeed, you'll come back to purchase more of my services! But don't just take my word for it: ⭐⭐⭐⭐⭐ "Alexandru is amazing to work with. His solutions are both on point tactically and strategically, and he has no problem thinking about the larger picture. His character is excellent, open and honest. Always ready to get things done, delivering, and an outstanding communicative team player. We've been working together for a while and hope to continue doing so in the future." ⭐⭐⭐⭐⭐ "From another planet. He understood perfectly what I needed in a few words. Very professional, exquisite coding, he even recorded a video explaining the code. Absolutely amazing. Recommended 100%." Though with some, it's just not meant to be - some signs may include: ⛔️ You think you can get someone else to do it cheaper ⛔️ You're not willing to adapt based on fresh information found during the work process ⛔️ You think freelancers are beneath you ⛔️ You don't appreciate the full process that goes into creating a successful SaaS I sold my first website when I was 13 years old. Since then, I had the opportunity to work on a wide variety of SaaS startups that went on to raise funds from investors or get acquired. ⭐ What I'm currently involved in ⭐ ✅ Founder at WorkSwift, a marketplace for AI Agents ✅ Author of The SaaS Maker newsletter I love building SaaS products and I always pick the best tools for the job, prioritizing both speed and customer satisfaction. READY TO GET STARTED? NEXT STEPS: 1. Invite me to your job 2. I will send my proposal 3. We’ll iron out all the requirements and expectations 4. I'll get the work done professionally to ensure you love the end result 5. You’ll leave an awesome review at the end 😎

    With over 20 years experience developing software, I help businesses and organizations grow by offering software assessment, consulting, and custom development. There are thousands of fantastic software developers out there, why would you choose me? One thing that sets me apart is that my approach is not to just simply develop a custom solution. I'll work with you to figure out if you even need custom development. Many times there are existing solutions out there that can get you going immediately. Selecting an already on the market solution can save you thousands of dollars, but they don't always suit everyone's needs. If after review, you and I both come to the conclusion that a custom developed solution is indeed the best route, then I'm happy to put together a formal proposal and build it for you. I absolutely guarantee customer satisfaction, and this is how I do it. I don't bill by the hour, you will always get a completely fixed price upfront, and that price will not change. With a fixed price you'll know down to the nickel how much you will spend for my services. Someone who works hourly is going to give you an "estimate" which will just be a guess. You may or may not already know that 50% of software projects go over their estimate, and of those 75% go over by double. Not only do I guarantee my price, I guarantee my work. Once the solution is complete, rest assured that if you ever find an issue/bug I’ll fix it for free. For Life. This is not a special offering accounted for by increasing the price, this is how I work. I stand behind every solution I create. While the software I develop is stable, and built to last, it’s always possible that something unexpected will occur. When this happens, I will always address this issue, no questions asked. And finally, I offer a 100% money back guarantee. So, before we get to building your solution, lets talk and find out what I can do for you.
