Most software works until it matters. I build the kind that works when it matters. Over the last 10+ years, I've built and maintained full-stack systems across React, Next.js, Node.js, TypeScript, PostgreSQL, Docker, and cloud infrastructure — SaaS platforms, AI products, automation systems, real-time applications, and complex integrations. My focus is usually the parts that are easy to get wrong: architecture that scales, integrations that recover, pipelines that catch problems before users do. Most recently, I led the engineering team at Inspira AI — frontend, backend, database, infrastructure, the full picture. I helped shape the platform into a more robust AI-powered SaaS product and owned the critical systems that kept it running. The CEO there recorded a video testimonial about working with me. He said: "Very technically precise, meticulous. He wouldn't let things pass if they were subpar. One of the things that impressed me most was his honesty and integrity." Before that, I spent years freelancing — building automation tools, desktop applications, and custom business software for clients across different industries. That's where I learned to build for real-world usage, not just demos. Clients usually bring me in when they need more than someone to code tickets. They need someone who can think through architecture, identify risks early, scope honestly, and deliver software that is clean, stable, and built to last. I can help with: • SaaS product engineering • React / Next.js / TypeScript development • Node.js backend systems and API design • PostgreSQL schema design and optimization • Stripe, Google APIs, and third-party integrations • Docker, CI/CD, and deployment workflows • Multi-tenant architecture and reliability improvements If you need a senior engineer who can take ownership of complex product work from architecture to delivery, send me the details.
