Most clients contact me after another developer failed. APIs not syncing, payments failing, calculations wrong, apps crashing under real users — I specialize in fixing live production systems safely without breaking existing data. I’m a full-stack engineer focused on backend architecture, debugging, and recovery of broken projects. I don’t guess — I diagnose root causes. Problems I commonly solve • Payment & webhook failures (Stripe, Razorpay, etc.) • Incorrect calculations / database corruption • Slow or crashing servers • Broken integrations & third-party APIs • Real-time / WebSocket instability • Projects abandoned by previous developer My working approach 1. Reproduce the issue locally 2. Identify the real root cause 3. Apply safe patch (no risky edits on live data) 4. Add logs & protections to prevent recurrence 5. Document everything so you’re not dependent on me You won’t just get a fix — you’ll get a stable system you can trust. If your project is already live and something is going wrong, I can help.
