About this gig

Need a rock-solid Java backend fast?

I'm Hasnain, a Spring Boot specialist whos shipped 20+ APIs and microservices for SMEs and startups in PK, UAE, and the US. From secured endpoints to fully containerized services, I write clean, documented code that scales.

REST/JSON, HATEOAS, Swagger/Open API docs

JWT / OAuth2 security, role-based access

JPA + Hibernate with MySQL / PostgreSQL

Unit & integration tests (JUnit 5, Test containers)

Docker & docker compose, GitHub Actions CI

Optional deploy to AWS EC2 / Elastic Beanstalk

Why me

  • 1 hour average response
  • Daily progress updates
  • 100 % on time delivery & zero critical defects reported post launch (20 + projects)
  • 4 + years scaling Spring Boot microservices to handle 1 M + API calls per day

Workflow

1. DM me your spec or rough idea (Ill reply in minutes).

2. I send a scoped proposal + timeline.

3. Code in a private repo; you track every commit.

4. Demo, revisions, hand over, deployment support.

Hi! I’m Hasnain, a full stack engineer laser focused on Java Spring Boot back ends and React front ends. For 3 + years I’ve built secure, test driven APIs, microservices and pixel-perfect UIs that load in under a second and scale to thousands. Furthermore, I have also experience of Python libraries and WordPress website (woo commerce, elementor pro and divi). I can develop fully functional end to end web apps.
