If you wanted a generic template or a massive, slow-moving agency, you’d be on a different page. I operate at the intersection of high-end web architecture and brutal technical honesty. For nearly two decades, I’ve been stepping in as a fractional CTO and elite engineer to rescue projects, build rock-solid digital infrastructure, and design scalable systems that don't break under pressure. No hand-holding required, no outsourced communication delays, and absolutely no fluff. Just bulletproof code and strategic execution. You get a senior partner, not just another ticket-taker. less -

I work on web applications, SaaS platforms, MVPs, admin dashboards, mobile apps, APIs, databases, automation workflows, AI-powered tools, CMS websites, e-commerce systems, internal business software, Excel automation, PDF generation, Unity/C# projects, and device-related software development. My main focus is creating clean, reliable, and user-friendly products without unnecessary complexity. I can help with new product development, existing application improvements, bug fixing, feature updates, responsive UI/UX improvements, backend development, database design, API integrations, payment workflows, cloud deployment, reporting tools, spreadsheet automation, document generation, embedded software support, hardware-related integrations, and long-term maintenance. I work with React, Next.js, TypeScript, JavaScript, Node.js, Express.js, Laravel, PHP, Python, FastAPI, Django, Supabase, Firebase, PostgreSQL, MySQL, MongoDB, Stripe, PayPal, OpenAI API, WordPress, Webflow, Shopify, React Native, Flutter, Expo, Unity, C#, Arduino, Embedded C/C++, PIC microcontrollers, PCB-related workflows, STEP/STP files, basic hardware communication, AWS, Vercel, Docker, Git, CI/CD, Excel, Google Sheets, CSV processing, and PDF generation workflows. For existing apps, websites, databases, APIs, plugins, automations, spreadsheets, PDF workflows, Unity projects, C# scripts, embedded systems, Arduino projects, PIC-based projects, hardware-connected applications, device control workflows, PCB-related files, STP/STEP files, or business systems, I first review the current structure and identify the safest way to improve it without unnecessary rebuilding. I can help with full-stack web application development, SaaS and MVP development, admin dashboards, internal tools, API integrations, AI features, chatbot workflows, database fixes, Excel dashboards, PDF automation, e-commerce websites, CMS websites, mobile apps, Unity development, C# scripting, Arduino support, embedded software, PIC microcontroller support, PCB-related workflow support, STP/STEP file review, bug fixing, refactoring, performance improvements, and deployment. I prefer projects where the client has a clear business goal, an existing issue to solve, or a product that needs reliable development support. I do not take on work outside my real experience, such as specialized tax compliance, Oracle/SAP financial consulting, gambling systems, adult content, academic cheating, platform abuse, unsafe automation, or advanced hardware engineering work that requires formal electrical certification. If you need a developer who can understand your requirements, review the current setup, build clean features, fix issues, connect software with hardware workflows, and deliver stable software with clear communication, I would be happy to help.
