I build production-grade audio plugins, embedded/hardware systems, real-time 3D tools, and AI-powered software for startups and studios, spanning C++/JUCE DSP engines, sensor/embedded firmware, WebGL configurators, and AI pipelines, shipped end to end. My strength lies in pairing rigorous engineering with design precision: the result is software that's not just functional, but fast, polished, and intuitive to use. Core skills: Embedded/Hardware: C++, ESP32, Raspberry Pi, SocketCAN, LiDAR, sensor integration and correction Audio/DSP: JUCE, C++23, VST3/AU/CLAP, FFmpeg, custom plugin GUIs 3D/XR: Three.js, WebGL, WebXR, Unity, Unreal Engine, OpenGL, Blender AI/ML: Python, PyTorch, OpenCV, RAG, FastAPI, automation workflows Full-Stack: Next.js, React, Electron, Node.js, Postgres, Go, Hono, Cloudflare-native architectures (Workers, D1, R2) for SaaS products and creative tools I do my best work as an ongoing technical partner, on retainer or across multi-phase builds, for teams shipping complex creative, embedded, or AI-powered software. Shorter projects are welcome too, but I'm most effective when involved from architecture through launch.

I build production software using an AI-first engineering approach, combining strong architecture fundamentals, modern full-stack development, automated testing, and cloud-native practices to deliver reliable products faster. Many developers use AI as a coding assistant. I use AI as an engineering partner throughout the entire development lifecycle: understanding requirements, exploring architecture options, generating implementation strategies, writing and reviewing code, creating tests, identifying risks, and continuously improving the product. With 10+ years of experience building business-critical applications, I have delivered SaaS platforms, CRM systems, customer portals, healthcare applications, enterprise software, mobile applications, and workflow automation solutions across multiple industries. My focus areas: AI-first full-stack application development .NET / C# backend systems and API architecture React, Next.js, and modern frontend applications SaaS platforms and business automation systems Cloud-native applications and CI/CD workflows Automated testing and quality-driven development AI integrations using LLM APIs, RAG, and intelligent workflows I have experience building scalable systems with: Backend: .NET, C#, Node.js, Python, FastAPI, REST APIs, GraphQL, microservices, authentication, authorization, and database architecture. Frontend: React, Next.js, TypeScript, JavaScript, component-driven UI development, responsive applications, and modern frontend patterns. Testing & Quality: Unit testing, integration testing, end-to-end testing with Playwright, Cypress, Jest, and test-driven development practices. Cloud & DevOps: AWS, Azure concepts, Docker, CI/CD pipelines, cloud deployments, environment management, and production monitoring. AI Engineering: OpenAI API, Claude API, Gemini API, prompt engineering, AI workflow automation, RAG systems, embeddings, and AI-powered business applications. My development process is built around a simple principle: AI increases engineering speed, but strong technical judgment ensures the final product is correct, maintainable, and scalable. I do not rely on AI-generated code blindly. I validate architecture decisions, review generated implementations, enforce testing standards, and use automated feedback loops to maintain production quality. Whether you are building a new AI-powered product, modernizing an existing platform, or creating scalable SaaS software, I can help transf

I'm a software engineer with 10 years of experience building mobile and web applications using React Native / Expo, Next.js, Supabase, Firebase, Node.js and Ruby on Rails. Over the years, I've worked on more than 30 professional projects across a variety of industries, gaining extensive experience building user-facing products from idea to production. While I have a strong technical foundation, I'm also highly product-focused. My goal is not simply to write code, but to build products that solve real problems, deliver value to users, and drive actual business revenue. I believe the best products are built iteratively. Rather than overengineering solutions, I focus on identifying the core features that create the most value, delivering them quickly, and establishing a solid foundation that can evolve as the product grows. When I'm not working on client projects, I'm building my own applications. That hands-on experience of designing, shipping, and iterating on products gives me a practical understanding of both the technical and product side of software development, which helps me work effectively with founders and entrepreneurs. I work mainly with Claude Code, which allows me to develop much faster and offer competitive pricing while still delivering high-quality work. Do not hesitate to reach out to discuss your project(s)!
