About

I studied Mechanical Engineering. I became a backend engineer anyway. Not because it was easy — but because I was obsessed with how software systems actually work under the hood. No CS degree. No shortcuts. Just years of building, breaking, and figuring things out. Today I build backend systems that real people depend on. At Nagarro, I lead the backend for a mobile banking platform used by 185,000+ active users across Saudi Arabia — with 99% uptime. We're talking reactive microservices in Quarkus, Redis caching strategies that cut database load by 46%, and CI/CD pipelines that went from 6-hour deployments to 50 minutes. Before that, at TCS, I built systems processing 230K+ daily transactions and led Kafka integrations handling 35K+ messages per hour with zero data loss. What I actually enjoy: designing systems that stay fast under pressure, mentoring developers who are earlier in their journey, and now — writing publicly about backend engineering so others don't have to learn the hard way. I'm exploring AI, LLMs, and MCP right now, because that's where backend engineering is heading and I'd rather be early than late. If you're a backend dev looking to grow, or a team that needs Java/Quarkus/Spring Boot expertise — let's connect.

  • Client: Riyad Bank
  • Remote Banking Project - Riyadh, Saudi Arabia
  • Lead backend development for a mobile banking platform serving 185K+ active users with 99% uptime — one of the largest Java/Quarkus deployments I've worked on.
  • Redesigned reactive microservices using Mutiny/Uni, cutting concurrent request handling time by 39% and reducing response times by 29% — the kind of change users actually feel.
  • Implemented a multi-layer caching strategy (Redis + in-memory) that reduced database load by 46% and meaningfully improved API performance under peak traffic.
  • Built CI/CD pipelines on OpenShift via GitLab that cut deployment time by 57% and eliminated downtime during releases entirely.

  • Client: Riyad Bank
  • On-Site Banking Project - Riyadh, Saudi Arabia
  • Took deployment cycle from 6 hours to 50 minutes by overhauling GitLab CI/CD pipelines on OpenShift — zero-downtime releases became the new standard.
  • Built optimized listing and data APIs that improved frontend response times by 34%, unblocking the UI team and accelerating product releases.
  • Rated "Highly Valuable" across multiple consecutive performance quarters — one of the few engineers on the team to hold that rating consistently.
