Startups and product teams hire me when they need a SaaS product built right — fast to ship, easy to scale, and ready for real users. I work across the full stack: React/Next.js on the frontend, Node.js or Ruby on Rails on the backend, and MongoDB or PostgreSQL underneath. More recently, I've been integrating AI capabilities (OpenAI, Claude APIs, LangChain) into SaaS products — turning basic apps into intelligent, automated platforms. What I build: → SaaS MVPs from 0 to production — auth, billing, dashboards, APIs → AI-powered features — smart search, chatbots, workflow automation → E-commerce & FinTech platforms — payment flows, KYC, real-time data → HealthTech apps — secure data handling, HIPAA-aware architecture → API integrations — Stripe, Twilio, third-party services → Legacy ROR codebase upgrades and performance tuning I don't disappear after handing off code. I write clean, documented, test-covered work that your next developer can actually pick up. Communication is clear, timelines are honest, and I flag issues before they become blockers. If you're building a SaaS product, a complex web app, or adding AI to an existing platform — let's talk. Send me a message and I'll usually respond within a few hours.
