    I Test In Prod 😁 ... Also, ✅ HIGHEST EARNING Flutter Freelancer on Upwork. Top Rated Plus (Top 1% of all freelancers). I have worked with 🌟High Profile Clients/Organizations🌟 in my Career. Top 2 reasons NOT to hire me: 1. You don't want your startup to get a swiss-knife problem solver. 2. You don't want to make a call. The main problem with developers from overseas is that they are pretty good at tech skills but they lack the proactivity of US guys. I always think of myself as a problem solver, not just a developer. Coding it's only a tool for rectifying issues. Sure, this might be a slightly over-simplified summary of what I do, but hey, who likes to read long descriptions anyways? Instead, let's jump on an initial 10-minute call so we can cover your project and decide how my development skillset will work best for you and your project.

    Hi there! My name is Sally Peck. I write code in Delphi, making VCL components, native Windows, Mac, iOS and Android apps. I use C# to make WPF, WinForms apps. I use python and Blender making Blender scripts. I am an Add-in-Express Team member, so if you're looking for an expert in Outlook, Word, and Excel Add-in development, I can get it done fast. I have multiple licenses of Delphi 10.4 latest and DevExpress, Fast Reports, so no need to buy them for me. (Reference: CodePatners Pty Ltd). I have an existing CI/Build environment, so once I commit, you can get builds immediately for C# and Delphi. I put extra effort needed to ensure your project meets required specifications and is delivered on time. I provide coding support, installation assistance and support documentation. I do UI/UX design, 3D models, 3D animations, so you get all rounded work. I provide a month's warranty for small works, while for larger jobs, up to six months warranty. Please see my happy customers and high ratings below.

    Backend frameworks Node.js, NestJs, Express, and front-end frameworks like React.js are my strong suits. Besides that, I've worked on several projects involving MongoDB, Azure cloud, Google Cloud Platform, AWS Lambda, Cognito, DynamoDB, Microservices, and the Serverless architecture, and I'm searching for new opportunities to use these skills. I'm not scared of new problems, and I'm interested in projects that require the use of cutting-edge technologies and web frameworks. If the project requires the use of technologies that I am unfamiliar with, it is not a challenge for me to read the documents and put what I have learned into effect. What my clients have to say about me: ⭐️ - "Dhiraj is an excellent experience and shown great professionalism and work ethics." ⭐️ - "Dhiraj was very prompt and helpful in getting us through a particular problem with AWS Lambda. Highly recommend his work!"

    The way I see it, a person hiring me for a job will benefit in two ways. Number one: my client will always get someone who delivers on time, Second: I'm always available to my clients. Hence the term, Dependable and Committed. I like solving problems and presenting these solutions in a friendly way. I bring solutions to you, flavored explicitly to your needs. Not only will I do the job, but I will also engage myself in coming up with new solutions that can solve the project better. I work on NodeJS, MongoDB, and PostgreSQL. I also have experience deploying these projects to Heroku. I have completed projects on these frameworks. I believe in open and frequent communication between my clients and me so that everyone involved is always on the right page. I look forward to hearing from you and can't wait till we work together.

    I can't say for sure but I have the impression that very few people (if any) in the IT field have read the "Message to Garcia" by Elbert Hubbard. I have read it and I dare to consider myself one of the people, who are able to "bring the message". There always will be someone who is more creative, knows more or works faster than me. I am aware of that and I accept it. Still, I am quite confident of being a better prepared professional than the average IT guy. I have 20 years of experience in programming, database modelling, system design and architecture, business processes analyses and automation, basic managerial accounting, Linux and network administration, Asterisk (FreePBX) configuration. I have successfully solved various business-related software and hardware challenges. Being able to combine both low-level and high-level allows me to work on wide range of tasks. I have reverse engineered and fully decompiled about a dozen Delphi components and desktop applications. Assembler was my 2nd language (after BASIC) and my first significant application was a player for tracker music entirely written in Assembler - with bass/treble digital filters. I like digging deeper and understanding the root cause. I am quite good at debugging and troubleshooting - and this is not an empty claim. Some of my achievements: - developed 2 full-blown ERPs (for Walltopia and Composite-X) - developed 2 accounting / warehousing applications with OLAP reporting and hierarchical multi-dimensional accounts - developed Windows service daemon for logging Skype chats to a REST API in real-time - ported one large desktop application (Interactive Delphi Reconstructor) from Borland CBuilder to Delphi - implemented a company-wide real-time backup solution using Yadis or Bvckup, Samba and NappIT on OpenIndiana - developed Linux daemon for controlling large LED strips based on WS2811 (and organized into X/Y matrix) through TCP/UDP socket - developed combined CDR reporting, matching information from the local Asterisk PBX with billing information from the VoIP providers - implemented Linux daemon for reading SMDR/CDR data from Panasonic PBX TDA-200 and storing in MySQL with reporting capabilities - developed custom reporting module for a 3rd party security access control system and integrated it with the in-house ERP system I choose my clients as carefully as you choose your freelancers. I value honesty, respect, good communication, good sense of humor, intelligence, modesty, kindness, generosity. I prefer to develop from scratch custom business solutions automating the workflow of small businesses. My previous experience with the 2 ERP systems I already developed (and which are used 24/7 by customers and employees) is of enormous benefit. I feel truly happy when I am able to help a client by removing the burden and simplifying the workflow. What can you expect from me: - educating and explaining the things which are too technical and unfamiliar to you - asking good questions - providing meaningful advises and recommendations - not trying to suck additional money by finding extra work of low business value - understanding your real business needs and goals - keeping you from making worthless or unwise expenses - excellent responsiveness - taking precautions against damaging your data - really listening to you and your problems/pain points - acknowledging my faults - enjoying good jokes - not quietly disappearing after faced with some tough challenge - honestly admitting when I do not know something or not being qualified enough - not over-complicating the solution - being available for support and further assistance after the final deployment - solving difficult problems - positive skepticism - breadth of knowledge - ability to “finish” - introspective, self-motivated to constantly improve - perseverance, scrappy in the face of setbacks, doesn’t “get blocked” - systems design ability - empathy for users - taking pains to write readable and maintainable code - methodical and analytical: can diagnose the most mysterious bugs or find the source of performance bottlenecks
