I help startups and engineering teams ship faster by integrating AI-first development workflows, LLM agents, custom MCP servers, local/cloud AI models, and production-ready automation into real codebases. I use tools like Claude Code, Codex, OpenCode, LM Studio, llama.cpp, and other AI engineering tools in production every day. I design structured .md workflow files, repo instructions, agent rules, and context-management systems that reduce token waste and make AI-assisted development predictable, efficient, and scalable. What I can help with: - LLM agents for existing or new products - Custom MCP servers and AI tooling around your workflow - AI-assisted development process implementation - Claude Code / Codex / local LLM setup for teams - RAG, automation, codebase analysis, internal dev agents - Fullstack development across web, mobile, desktop, embedded, and gamedev - Local and cloud model integration - Rapid prototyping and production-grade implementation I am not tied to one stack. I have 20+ years of commercial software engineering experience in startups, and 10+ years in open source as the author of multiple libraries and frameworks. Core technologies: C, Objective-C, Swift, JavaScript, TypeScript, Java, Kotlin, Python, embedded systems, game development, web, mobile, and backend systems. I work remotely only. My focus is simple: help your team build faster, reduce engineering friction, and turn AI tools into a real production advantage.

I build cross-platform mobile apps and games that launch, scale, and support real users, not just prototypes. As the founder of BafaTech Studio, I've delivered Flutter-based products across health and wellness, education, family, and gaming sectors, leading projects from concept and architecture through development, testing, deployment, and post-launch support. My core stack includes Flutter, Dart, Supabase, PostgreSQL, and Supabase Edge Functions. I build full-stack, production-ready applications with clean architecture, maintainable code, and a strong focus on performance, reliability, and user experience. What sets me apart is a unique combination of software engineering and more than 18 years of enterprise technology and cybersecurity architecture experience. This background allows me to build applications with security, scalability, and long-term maintainability in mind from the very beginning. I hold a Master's degree in Cybersecurity and believe security, scalability, and maintainability should be built into a product from day one. Whether you need an MVP, a production-ready mobile application, or a long-term development partner, I can help turn your vision into a reliable, scalable product. Message me to discuss your project.

I'm a 21-year veteran developer who's been coding since age 9. Currently, my team and I are developing EduDiamond – an AI-powered educational management system.

I help founders and product teams ship production AI products and full-stack systems end-to-end: C#/.NET backends, Next.js apps, and native Swift/SwiftUI clients — from architecture and API design to deployment, observability, and maintenance. Best fit when you need one engineer who can bridge product, backend, web, and native surfaces without creating long-term mess. What I usually build: • AI features that work in production: streaming chat, tool/function calling, structured outputs, assistants/workflows, RAG, MCP servers, evals, and cost/latency controls • Full-stack delivery: ASP.NET Core APIs, background workers, auth, integrations, OpenAPI-first contracts, Next.js, Supabase/Postgres, Vercel, AWS, payments, email, and analytics • Native/platform work when needed: Swift/SwiftUI for iOS, macOS, and watchOS; WPF, WinForms, WinUI 3, Avalonia, Uno, VSIX tooling, COM/C++ interop, installers, Telegram Mini Apps, and Chrome Extensions I use AI to accelerate delivery, not to lower the bar: clear contracts, reviewed code, practical tests, instrumentation, and production-ready delivery. If you need a senior engineer who can own the system and ship reliably across backend + web + native clients, send me your goal, current stack, and constraints.
