What I'm looking for

I seek hands‑on engineering roles building scalable backend and full‑stack systems, with opportunities to own architecture, improve performance, and deploy production services in cloud environments.

I am a full‑stack Java developer who builds scalable, production‑ready web applications and backend systems with a focus on performance, multitenancy and automation.

In recent internships I architected and deployed multi‑tenant CRMs using Spring Boot and PostgreSQL, implemented database routing and automated provisioning to dramatically reduce onboarding time, and built backend‑driven Chrome automation to accelerate form submission workflows.

My projects demonstrate end‑to‑end ownership — designing REST APIs, RBAC, JWT auth, containerized AWS deployments, CI/CD, and production optimizations that achieved high uptime and sub‑second response times.

I continually improve maintainability and performance by using layered designs, native SQL where appropriate, and cloud storage strategies; I seek roles where I can contribute to scalable architectures and ship reliable systems.
