Writing and optimizing Dockerfiles for backend services — multi-stage builds, layer caching, and container best practices. Learning production DevOps workflows hands-on alongside the engineering team.
/about
Currently in Semester 7
I'm a BS Software Engineering student at University of Mianwali, based in Pakistan, focused on backend engineering with a growing pull toward DevSecOps and infrastructure work. Currently interning at Dafi Labs and Orbit-i as a DevOps Engineer Intern — writing Dockerfiles for backend services at Orbit-i while building CI/CD and cloud workflows at Dafi Labs. Most of my learning happens by shipping — real deployments over local demos, PostgreSQL over H2, production incidents over tutorials.
Day to day I split time between a Windows machine (i7-14650HX, RTX 4070) for Spring Boot development and CI builds, and an Ubuntu laptop running as a self-hosted GitHub Actions runner — alongside an ARM64 EC2 instance in production.

Why work with me
What sets me apart as a backend & DevOps engineer — beyond the resume keywords.
Production-first mindset
Two Spring Boot systems live in production — not localhost demos. I ship on AWS EC2 with real SSL, managed databases, and CI/CD pipelines.
Backend + DevOps in one
I write the API and deploy it — Docker, Nginx, GitHub Actions, RDS, Redis, and infrastructure hardening included in every project.
Security built in
JWT refresh rotation, RBAC with @PreAuthorize, BCrypt, OTP rate-limiting, TLS 1.2/1.3 — security is part of the architecture, not an afterthought.
Strong academic record
3.80 CGPA in BS Software Engineering (Semester 7). Solid CS fundamentals — DSA, OOP, OS, Networks, DBMS — applied directly in production code.
Self-driven learner
AWS, CI/CD, and Git certified. Dual DevOps internships at Dafi Labs and Orbit-i. Exploring Kafka, Kubernetes, and RAG/pgvector on my own stack.
Team-ready from day one
Jira-certified for sprint planning and backlog management. Document APIs with Swagger/OpenAPI, write clean commits, and debug production incidents calmly.

- Architected role-isolated REST API for the full paper lifecycle — SUBMITTED → UNDER_REVIEW → ACCEPTED / REJECTED / REVISION — across Admin, Researcher, Reviewer, and Reader roles via
@PreAuthorize. - Stateless JWT auth with refresh token rotation; access tokens verified in-memory. Redis OTP rate-limiting uses atomic
setIfAbsent()to prevent race conditions under load. - Deployed on AWS EC2 behind Nginx with Let's Encrypt SSL, TLS 1.2/1.3 hardening, and HTTP→HTTPS redirect. RDS (PostgreSQL) + ElastiCache (Redis) as managed backends.
- CI/CD via GitHub Actions: Maven build → Trivy scan → Docker image (SHA-tagged) → Docker Hub → SSH deploy — images built off-server to preserve EC2 memory.
- Dual-mode object storage with AWS S3 + MinIO; SendGrid with SPF/DKIM domain auth for OTP email; 30+ endpoints documented via Swagger / OpenAPI 3 with a Postman collection.

- Secure REST backend with JWT auth, refresh token rotation, and a locked-down Spring Security filter chain.
- Server-side challenge validation engine for math and QR-based alarm dismissal workflows.
- Redis for session/token lookups, PostgreSQL for alarm and user persistence via Spring Data JPA.
- Diagnosed and fixed a Jackson version conflict and duplicate Spring Security filter registration caused by transitive dependency clashes, resolved via explicit version pinning in
pom.xml.
