I’ve been building web applications for more than 10 years, mostly for startups and SaaS companies. Most of the projects I join aren’t greenfield projects. They’re products that already have users, existing code, tight deadlines, and features that need to be shipped without breaking anything. That’s the kind of work I actually enjoy. Over the years I’ve worked on React, Next.js, Node.js, PostgreSQL, Supabase, AWS and Stripe integrations. Those are simply the tools I’ve used. What matters more to me is understanding how the product works before writing code. A few examples from recent projects: • Reduced checkout abandonment by 18% after redesigning part of the purchasing flow. • Cut infrastructure costs by around 35% by rebuilding the deployment pipeline and automating releases. • Built and maintained multi-tenant SaaS applications used by growing businesses. • Integrated Stripe, Salesforce and third-party APIs into existing production systems. One thing clients often tell me is that I get up to speed quickly. I don’t need weeks to understand an existing codebase. I ask questions, understand how the system works, and start contributing as early as possible. I’m also comfortable working directly with founders, designers and product managers. Sometimes that means discussing technical solutions, and sometimes it simply means pointing out a cheaper or simpler way to build something. If you’re looking for someone to help move your product forward instead of just completing tickets, I’d be happy to have a conversation.
