Owning backend systems, AI-accelerated delivery, and AWS infrastructure at production scale.
I'm Deepak Kumar, a backend-focused software developer with 4.5+ years of experience across eSports, FinTech, HealthTech, and Real Estate. I build cloud-native platforms, realtime experiences, payment flows, compliance systems, and production-ready APIs with a strong ownership mindset. I currently lead delivery of the full eSports ecosystem and digital store for e& (Etisalat), serving a 1.5M+ user base. I'm also an early adopter of AI developer tools since ChatGPT's launch, using them to move faster across design, debugging, delivery, and engineering communication.

I combine system design depth with product ownership and delivery calm.
Architecture
Backend systems built for scale, compliance, and realtime behavior.
From graph-based AML flows to WebSocket-driven tournament systems, I design services that stay maintainable while supporting high-throughput product use cases.
Ownership
Comfortable across API design, AWS infrastructure, deployment, and performance.
I don't stop at writing services. I work through deployments, reverse proxy and load balancing setups, integrations, failure paths, observability, and the production realities that recruiters and hiring managers care about.
Leadership
Trusted to align teams, stakeholders, and clients around shipping outcomes.
I've led a 5+ member engineering team, collaborated directly with enterprise clients, and delivered systems that balance speed, reliability, and business value.
Professional Experience
High-impact backend work across products, platforms, and production environments.
