►Capabilities: ----------------- ☑ Design, review, hand-assembly, troubleshooting, and rework of electronic designs. ☑ Microcontroller programming. ☑ High-speed signal routing (USB, HDMI, Ethernet, etc.) involving microprocessors or FPGAs with DDR3 or DDR4. ☑ Ultra-low power designs consuming microamps during standby for long battery life. Use of Altium Designer, KiCad, and Cadence OrCAD. With my Altium subscription, I can share designs over Altium 365 to provide you with a convenient view of progress through your web browser. ☑ PoC (Proof of Concept) app development. ☑ In-house equipment including an oscilloscope, multimeter, power supply, soldering iron, hot-air rework station, hotplate, and optical inspection equipment. ► Typical Deliverables: ---------------------------- ☑ All manufacturing, design, source code files, and (if desired) Altium 365 sharing if done in Altium. ☑ Hand-assembly of PCB prototypes. ☑ For high-volume production, an affordable arrangement for turn-key manufacturing. ☑ Free troubleshooting support for simple problems long after an ended contract with me. ► Typical Design Workflow for Circuit Board Design from Start to Finish: ---------------------------------------------------------------------------------------- Actual workflow may vary for unique projects, but each step of the way I will work with you to ensure your requirements are met. 1️⃣. The client shares their initial requirements (ideas, features, recommended parts, etc.). 2️⃣. Estimation for hourly/fixed-price. Projects with: a) well-defined requirements, fixed-price is acceptable, b) requirements that are more open-ended, hourly is acceptable. 3️⃣. A contract is started. 4️⃣. An initial schematic is designed with readily available components, along with a BOM (Bill of Materials). Development boards, breadboards, and simulators can be used for prototyping before circuit board design. 5️⃣. Circuit board placement and layout. 6️⃣. Prototype material procurement: BOM is ordered. Gerber files are generated and sent to a circuit board fabricator for the production of bare boards. 7️⃣. Bare circuit boards can be hand-assembled in-house by me. For more complex boards with hundreds of surface-mount parts, turn-key manufacturing can be arranged. 8️⃣. Prototype boards are tested according to the client's requirements. 9️⃣. All design files are updated to reflect any modifications needed for the prototype circuit board. These files are shared with you, the client. 🔟. Now any capable electronics manufacturing service can produce your project. I have been professionally consulting with clients since 2018. Please feel free to challenge me with your interesting projects! I strive to answer invites within 24 hours.

My main strength besides my programming ability is communication. I ask a lot of questions so that you get your product delivered on time, on budget, and exactly as specified. I also have a creative side and an eye for design for when you're not sure exactly what you're looking for when needed. I'm very flexible and work well under pressure.

I'm an independent software consultant specializing in web app development and design. Leveraging professional tools, I craft user-centric solutions tailored to your specific needs and budget. Drawing on experience at a Fortune 500 enterprise like Analog Devices Inc., I ensure a clear understanding of your project goals and handle the entire development lifecycle, including deployment. This means you can focus on your core business while I take care of building and launching your web application. I work independently and handle all aspects of your project, from design to deployment. This ensures a single point of contact and streamlined communication throughout the process. Feel free to schedule an interview to learn more about my approach and how I can contribute to your project. Who should hire me? - Startups seeking to build scalable web or mobile apps from the ground up. I leverage efficient and agile methodologies to create future-proof solutions that can grow with your business. - Individuals and small businesses needing guidance on web app development, scalability, and budgeting. My consultations translate your vision into a clear roadmap, ensuring cost-effectiveness and long-term success. - Entrepreneurs with evolving business models who require expert app development direction. I can help you navigate the ever-changing app landscape and find the best technology fit for your unique needs. - Mid-sized to large enterprises looking for a versatile developer. I offer a full spectrum of skills, from frontend development to full-stack expertise, with design and deployment experience to ensure seamless project execution. Why I Embrace a Multifaceted Approach? My journey began in architectural design, where I explored integrating technology into physical spaces. This experience instilled in me a strong foundation in research, reading, and problem-solving. While coding initially presented a challenge, I soon realized my design background provided a solid base for web development and UX/UI design. I transitioned to freelancing, allowing me to leverage my diverse skillset. The ever-evolving nature of the web industry demands flexibility and a thirst for knowledge. My research and reading skills, honed during my academic background, empower me to quickly adapt to new technologies and tackle challenges with enthusiasm. This research ability and understanding of abstract concepts are highly transferable to building startups and developing apps. As you know, most information is readily available online, and a significant portion of a developer's role involves reading documentation and quickly grasping complex ideas. This aligns perfectly with my strengths. Therefore, I prioritize staying up-to-date with the latest advancements in the field. I actively seek out new technologies and challenges, forsaking the comfort of relying solely on familiar methods. This commitment to continuous learning ensures I can deliver the most effective solutions for your project. Common Mistakes When Hiring Programmers Many clients struggle to identify the right skill set when hiring programmers and often end up with code full of bugs. Here are some common mistakes to avoid: 1. Underestimating frontend development's complexity: Frontend development can be just as complicated, if not more so, than backend development. Don’t assume it’s easier. 2. Believing enterprise experience guarantees better results: Just because someone has worked at a large enterprise doesn't mean they can build an app from scratch, especially if their experience is focused on optimization rather than creation. Also, many tech giants emphasize algorithms in their interviews, which, in my opinion, are less relevant in the age of tools like ChatGPT. 3. Assuming computer science degrees guarantee coding ability: While a computer science degree provides a solid understanding of programming concepts, it doesn’t necessarily mean the person can code effectively. 4. Hiring cheaper developers and ending up with messy code: Platforms like Upwork offer a global pool of developers, and while you can find reasonably priced talent, lower costs don’t always equate to quality work. 5. Developing and bug-fixing apps by multiple developers, especially on a fixed-price basis: The code needs to be constantly organized, cleaned, and updated. Apps built this way can become messy, leading to situations where a simple CSS fix takes hours. Code lines can grow into thousands, function names might not be descriptive, etc. This will be a total waste of your money! I'm not saying you must always hire me, but it's crucial to hire the right engineers who can do the right job for you! I understand that finding the right resources isn't easy, but I encourage you to take the time to do it right. Seek consultations, ask friends for help, and make sure you find the right fit for your needs. I look forward to hearing from you soon!
