I don’t just ship features. I build systems that survive real users, real data, and real business pressure. 🧠 My background spans full-stack web development, cross-platform mobile apps, desktop software, and practical blockchain integration. That means I can take a product from early concept through architecture, implementation, optimization, and deployment — without hand-offs or fragile glue code. 🌐 Web: High-performance apps with React, Next.js, and TypeScript, focused on scalability, clean state management, and well-designed APIs. 📱 Mobile: Maintainable Flutter or React Native apps with careful attention to performance, platform behavior, and long-term upgrades. 🖥️ Desktop: Fast, reliable software built with C++ and C#, including internal tools and system-level utilities where performance and OS integration matter. ⛓️ Blockchain: Smart contracts and Web3 backends built with security and real-world reliability in mind. I work with Rust and Solana development, and I build EVM smart contracts where correctness, testing, and audit-ready structure matter. I also handle the “boring but critical” parts: wallet flows, signing, backend integration, indexing, and monitoring — so blockchain features behave like real product features, not demos. ⚙️ Behind the UI, I design robust backend systems using Node.js, Python, or PHP/Laravel, backed by PostgreSQL or MySQL, and Supabase or Firebase when appropriate. I care deeply about data modeling, authentication flows, background jobs, and CI/CD — the unglamorous parts that decide whether a product scales or breaks later. 🤖 AI is something I integrate practically, not as a buzzword. I’ve built AI chat systems, content generation tools, workflow automation, and data-driven features that reduce manual work and unlock real product value. The focus is always reliability, predictability, and measurable impact. 🛠️ Clients work with me when they want a developer who thinks like an engineer, not just a coder. I help clarify requirements, spot architectural risks early, debug complex issues, and improve existing systems without breaking what already works. 🔧 Tech stack: React, Next.js, TypeScript, Node.js, Python, PHP, Laravel, Flutter, React Native, C++ / C#, PostgreSQL, MySQL, Supabase, Firebase, Solana (Rust), Smart Contracts (EVM), AI model integration, automation, GitHub Actions, CI/CD. ✅ What you get: Clear communication, honest timelines, clean code, and software built to last — with AI and blockchain used where they truly add product value. 🎯 If you want one developer who can own web, mobile, desktop, blockchain, and AI end-to-end, you’re in the right place. moins

My core specialty is conversational AI over the phone: AI receptionists, appointment setters, outbound agents, and call automation built with ElevenLabs, Whisper, Twilio, LiveKit, Agora, and modern LLM stacks (OpenAI, Claude). I’ve delivered systems that answer every call, book directly into calendars, send transcripts in near-real time, and gracefully escalate to humans when needed. For structured, compliance-sensitive use cases, I also implement Dialogflow CX as a deterministic conversation layer—paired with LLMs where flexibility is required. This hybrid approach gives clients both reliability and natural speech. Beyond voice, I consult on: OpenAI API and LLM agent pipelines Automation workflows across web, mobile, and cloud Real-time systems, telephony, and event-driven architecture Earlier in my career, I led and supported large enterprise platforms and intranet migrations (Jive, SharePoint, Confluence). Today, my focus is on future-forward, human-feeling systems— vibe-coded applications: intuitive, immersive software that users don’t have to think about. If you want something that actually works in the real world—not just a chatbot—I’m happy to show live examples. moins
