Open to senior backend roles · India / Remote

I build backend systems that
move money and don't
fall over at scale.

Mohammad Yusuf Khan. Java engineer with 3 years shipping Spring Boot microservices for ERP and payments. On the side, I build full-stack interfaces for real businesses because shipping to actual users makes you a better engineer.

02 / Trajectory

Where I've shipped.

Two roles, both backend-heavy, both with cross-functional ownership beyond the JD.

03 / Shipped

Six websites for real businesses.

Restaurants, fashion, transport, gaming. Built independently — research, design, code, deploy, talk to the owner, fix what's confusing.

None of these were assigned to me. I found the businesses, pitched, scoped, built, and shipped. The fastest engineering education I've had — because the feedback loop is the owner calling you when something breaks.

04 / Systems

Production-grade backend systems.

Three platforms I designed end-to-end — from architecture sketches to deployed, observable services.

In progress · Doctors Group

Cloud-native clinic platform

Full-stack clinic automation: patient flows, billing, inventory, notifications. Microservices behind a React UI, secured with Spring Security + OAuth 2.0, async schedulers for reminders and stock sync, deployed Dockerized on AWS with Jenkins CI/CD and Prometheus/Grafana on top.

Payment reconciliation & sync engine

Spring Boot services that sync and reconcile payments across ERP, QuickBooks, and gateways. Multithreaded background workers and async jobs absorb 10K+ daily transactions; JPA/Hibernate tuned with care for reporting reads. Secured with JWT/OAuth2, monitored via Grafana.

Expense & invoice automation

End-to-end expense and invoice workflow with event-driven processing, validation pipelines, and configurable approval chains. Reusable microservices, role-based modules, automated deploys via Maven/Gradle + Jenkins, documented with Swagger and tested with JUnit + Postman.

BGMI streamer toolkit

A web app + companion mobile app for Indian BGMI streamers and gamers — built because the existing tooling is fragmented. Goal is to give creators a single dashboard for sensitivity configs, tournament tracking, and stream overlays. Backend in Spring Boot, mobile in React Native, designed mobile-first.

06 / Note

A short note on how I work.

Most of what I know I learned by breaking things. When I wanted to understand frontend, I went and built six websites for actual businesses—because nothing teaches you faster than a restaurant owner texting at 11pm asking why their site won't load.

I write production Spring Boot for the day job, but I fully understand what it costs to scope a project, ship it, and support it. If you need someone who will own a system end-to-end without theatrics, let's talk.
