AI Product Engineer | SaaS MVP | AI Integrations Full-Stack Developer
I'm an AI Product Engineer and founder - I design, build, and ship AI-powered products fast. I launched Nocodly, an AI assistant SaaS platform, entirely solo - from idea to paying users. No team, no agency. That experience taught me how to move fast, make smart tradeards, and build things that actually work in production - not just demos. My edge is knowing when to write code and when to let AI do the heavy lifting. I use Claude Code, Cursor, and OpenAI APIs daily to move at a speed that wasn't possible two years ago. The result: founders get a working product in weeks, not months. What I build: — AI-powered SaaS platforms and startup MVPs — Full stack web applications (Next.js, React, Node.js, TypeScript) — Desktop applications (Python, Electron) — AI integrations (OpenAI API, Claude API, Jina AI) — Chatbot and AI assistant systems (web, Telegram) — Admin dashboards, CRM systems, internal business tools — Workflow automation and API integrations — Multi-tenant SaaS applications — Marketplace platforms and booking systems — Stripe payments, subscriptions, and billing systems — Cloud infrastructure and deployment (Railway, Vercel, Supabase) — Real-time databases and scalable backend architecture — Authentication systems and role-based access control — Landing pages and conversion-focused UI — Analytics integration and funnel tracking — Telegram bot development and automation — AI prompt engineering and LLM architecture — Structured outputs and schema design — Quality validation systems for AI responses — Evaluation harnesses and AI output testing — API-first platform architecture — SaaS onboarding flows and user management — Notification systems (email, in-app, Telegram) — CSV and PDF export systems — Reporting dashboards and data visualization Tech stack: Frontend: React, Next.js, JavaScript, TypeScript, Tailwind CSS, responsive web design Backend: Node.js, Express.js, REST APIs, Webhooks, authentication systems, server-side logic Database: Supabase, PocketBase, PostgreSQL, Firebase, real-time databases Cloud: Railway, Vercel, cloud infrastructure, production deployment, scalable systems AI: OpenAI API, Claude API, Jina AI, AI agents, AI automation, vector search, AI chat systems, LLM integrations, prompt engineering Payments: Stripe, Stripe subscriptions, Stripe checkout, recurring billing, SaaS billing systems, webhook handling, invoice systems Tools: Claude Code, Cursor, GitHub, VS Code, AI-assisted development workflows, agile startup development What I also help with: — Bug fixing and performance optimization — API debugging and backend troubleshooting — Database fixes and scalable code refactoring — UI/UX improvements and modern interface design — Production support for web applications and SaaS systems — Code review and architecture consulting — Performance audits and scalability planning — Migration from legacy systems to modern stacks — Integration of third-party APIs and services — Security improvements and authentication hardening Industries I've worked with: — SaaS and software products — AI and automation tools — Booking and scheduling platforms — E-commerce and marketplace systems — Business productivity tools — Customer communication platforms — Content and media platforms Why founders hire me: I do more than just write code. I help validate ideas, structure scalable architecture, improve product direction, and launch fast. I understand SaaS business models, unit economics, and what it takes to go from zero to paying users - because I've done it myself. I think like a founder, not a ticket-taker. I'll scope it properly, tell you what's worth building, push back on bad ideas, and ship without overbuilding. If you're a founder with a real problem and need someone who gets both the technical and business side - let's talk.
