About this gig

Is your web application broken? Stop losing users and revenue to technical glitches.

I am a Senior Software Engineer and Tier III Product Support Specialist with 3+ years of experience in high-stakes environments like i2c inc and Eon Health. I specialize in "rescue missions"taking broken, buggy, or unoptimized code and making it production-ready.

Whether its a MERN stack crash, an API that won't connect, or a deployment nightmare on AWS/Vercel, I apply an enterprise-level Root Cause Analysis (RCA) to fix the problem permanently, not just patch it.

What I Can Fix For You:

  • Full-Stack (MERN): React.js state issues, Node.js/Express logic, and MongoDB query optimization.
  • API & Integrations: REST/SOAP, Webhooks, and third-party service connections.
  • Security & Integrity: AES-256 encryption, SHA-256 hashing, and JWT Authentication.
  • DevOps & Cloud: SSL/HTTPS fixes, DNS configuration (Cloudflare/GoDaddy), and AWS S3/CloudFront issues.
  • Data Automation: Python-based parsers (Excel to JSON) and automated file monitoring.

  • Winner: Global Hackathon on AI & Blockchain (AKTI).
  • Expertise: Arfa Karim Fellow with 95% Customer Satisfaction in Tier III Support.
