I help clients fix bugs, improve existing features, and build small-to-medium web app functionality using ASP.NET Core, Blazor, React, Entity Framework, and API-based architecture. I can help with: • ASP.NET Core / Web API bug fixes • Blazor and React UI fixes • React components and API integration • API integration and backend logic • EF Core and SQL database issues • Authentication and validation • Business rules and admin panels • Docker deployment and production troubleshooting My experience includes real production work with payments, SSO, Redis caching, AWS S3 storage, logging, automated testing, and CI/CD deployment pipelines. I’m strongest on the .NET/backend side, including API design, validation, business logic, EF Core, code refactoring, and production bug fixing. I also work with React for UI fixes, component updates, API integration, frontend improvements, and small feature implementation. If you need someone to understand an existing codebase, find the issue, and make a clean fix without overcomplicating it, I can help.

I help businesses automate their workflows, connect different systems into one ecosystem, and build custom software that saves time. I'm a Senior Full-Stack Developer with 30+ years of software development experience, specializing in web applications, AI integrations, business automation, APIs, and custom internal systems. Whether you need a web platform, a mobile app, an AI-powered assistant, or complex integrations between multiple services, I build solutions that are scalable and designed for long-term growth. A lot of my work also focuses on building practical solutions using APIs, Google Sheets, and AI tools. What I build: Full-stack web applications Business automation platforms Automating business workflows AI-based tools (ChatGPT, OpenAI, Whisper, AI Agents, etc.) API integrations for connecting APIs between different platforms SaaS products, web applications, and backend systems CRM & ERP integrations Internal business systems and admin panels Admin dashboards, reporting & analytics systems Mobile applications (Flutter, AppSheets) Google Workspace & Google Sheets automation E-commerce integrations Frontend: React, Next.js, JavaScript, TypeScript, HTML, CSS Backend: Node.js, Python, PHP, Google Apps Script Databases: MySQL, PostgreSQL, SQL Server, MongoDB, Firebase Cloud & APIs: REST APIs, GraphQL, OAuth, Webhooks, Google Cloud, AWS AI: OpenAI API, ChatGPT integrations, AI assistants, LLM-based workflows, speech-to-text solutions (Whisper) I've built integrations with platforms including: Shopify • Stripe • QuickBooks • HubSpot • Salesforce • GoHighLevel • Zoho • Twilio • Meta/Facebook • Google Workspace • Trello • Pipedrive • Mailchimp • Telegram • WhatsApp • Airtable • Notion • and many others. I prefer simple, safe solutions that solve real business problems. In most cases, I choose custom development over no-code tools because it gives more flexibility and long-term stability. I'm available for both short-term projects and long-term partnerships involving: • Full-stack web development • Business process automation • AI implementation • API integrations • SaaS development • Mobile applications • System architecture • Internal business platforms

Fractional CTO and software architect with 25+ years of hands-on engineering experience. I help founders, startups, and growing companies make better technical decisions, build stronger engineering systems, and scale products with less risk. For the last 5 years, I have been building Growity Systems as CTO and co-founder, leading architecture, product development, and engineering execution end-to-end. This experience strengthened not only my technical depth, but also my ability to make pragmatic decisions about scalability, delivery, product trade-offs, team structure, and business impact. I work with companies that need senior technical leadership without hiring a full-time CTO. My role typically includes defining architecture, improving delivery discipline, raising engineering quality and technical standards, and helping teams execute with more clarity and consistency. My background combines executive-level technical leadership with deep hands-on development. I am most useful when a company needs someone who can move between business goals, product priorities, system architecture, and implementation details without losing speed or quality. I can help with: • technical strategy and architecture • product-to-engineering translation • system design for scalable and high-load platforms • team leadership and engineering process improvement • codebase review, refactoring, and modernization • hiring, team structuring, and technical due diligence • stabilizing and restructuring troubled projects My strongest domains include fintech, trading infrastructure, digital asset systems, and high-performance backend platforms. I have worked on low-latency systems, exchange integrations, market-data processing, trading platforms, distributed services, and complex backend architectures. I am also actively integrating AI into engineering and business workflows, including autonomous AI agents for code review, research, internal automation, and decision support. I approach AI pragmatically: as a tool for improving delivery speed, engineering quality, and operational efficiency. Clients typically bring me in when they need a fractional CTO to lead the technical side of the business, a senior architect to design or stabilize a critical system, or a hands-on technical leader to bring structure, direction, and execution to a growing team. If you need a senior technical leader who can combine strategy, architecture, delivery, and hands-on execution, I can help as a fractional CTO or software architect.

Technical project manager and hands-on engineer - 18+ years in Software Engineering, teams up to seven engineers, and AI integration. My work has shipped into simulation software adopted by Apple and Airbus, AAA engines at Ubisoft, Autodesk Revit, BMW and Panasonic vehicle systems, and a CME-certified trading platform. Most project managers cannot read the code. Most engineers do not want to run the project. I do both, which means fewer translation layers between you and a working result. WHAT I DO Technical project management - Agile/Scrum, JIRA, roadmaps, estimation, hiring, leading teams up to seven engineers AI integration - LLM APIs, automating manual workflows, AI-assisted delivery. Led product delivery at Zentry AI Engineering leadership on hard problems - C/C++, computational geometry, 3D graphics, multithreading, performance-critical systems Legacy debugging others have given up on - undocumented code, original authors long gone, intermittent faults SELECTED RESULTS Built "Human Exposure Analysis" solo in 3 months: skeleton-driven positioning of voxel human body models, a capability no competing EM simulation vendor offered at the time. The deciding functionality behind Apple adopting the software. Co-developed a shortest-path solver across 3D surfaces with obstacles (Dijkstra, custom raster optimisations, multithreading) for Airbus, computing minimum cable runs between aircraft antennas. Led the C/C++ team on broadcast IP video at Imagine Communications: EpicMV multiview monitoring and the Selenio Network Processor. Built a DropCopy client for a high-frequency trading platform and took it through CME AutoCert+ certification. Cloth simulation for Ubisoft's in-house game engine across PC, PS4 and Xbox One. Shipped a bilingual production site solo in 3 weeks: domain, Cloudflare infrastructure, build and release. Implemented a key algorithm which helped Autodesk Revit automate a ceiling construction tool - used C# and 3D graphics skills. HOW I WORK I own the whole problem: requirements, architecture, implementation, testing and delivery. I tell you up front what I cover and where you would need another specialist, so you get a realistic plan rather than an optimistic one. Send me the problem rather than the spec. Deciding what to build is usually the hard part. I also run a small Upwork agency (Smart Fox), so I can bring in an additional engineer when a project needs more hands, or deliver through the agency if that suits your procurement.
