What if your web app could load 2× faster and keep users engaged longer?
I help businesses turn ideas into fast, reliable, and scalable web applications that users love. With 2 years of hands-on experience and 20+ successfully delivered projects, I specialize in modern stacks like Next.js, Nest.js, TypeScript, PostgreSQL, MongoDB, Supabase, and AWS.
My approach is simple: performance, scalability, and clean code. For example, I recently optimized a Next.js application with server-side rendering (SSR) and AWS hosting, cutting page load times by 50%, which significantly boosted user engagement

FAQ
What do I need to share with you?
Your error message, a description of what's happening, and either your code files or a GitHub repo link.
Can you fix apps built with Lovable, Bolt, or Cursor AI?
Yes, this is one of my most common requests. These tools produce code that breaks under real-world conditions. I fix and stabilize them.
What if the problem is bigger than a single bug?**
I'll let you know upfront and recommend the right package before you pay anything.
Do you work on weekends?
Yes. I typically respond within 1–2 hours any day.
