What I'm looking for

I seek full‑stack or backend roles where I can build performant, secure systems, work across cloud and container platforms, and collaborate with cross‑functional teams to deliver measurable impact.

I am a full-stack software developer with hands-on experience across web and mobile technologies, cloud platforms, and system optimization practices. I have contributed to and maintained government and private-sector platforms, focusing on reliability and performance.

At National Informatics Center I develop and maintain projects under the Meghalaya Enterprise Architecture initiative, and I previously supported the Directorate of Census Operations' online platform. I have also worked in senior and contributor roles at multiple firms building portals, mobile apps, and internal platforms.

My technical strengths include JavaScript/TypeScript, Java, Python, PHP, Dart, and familiarity with Rust, plus frameworks such as Laravel, Spring Boot, Vue, React, React Native, and Flutter. I design and optimize databases (MySQL, MariaDB, PostgreSQL), integrate APIs, implement secure payment systems, and execute system migrations.

I deploy and operate applications on AWS, GCP, Heroku, and DigitalOcean, use Docker for containerization, Git for version control, and manage Apache2/NGINX web servers. I seek roles where I can drive performant, secure systems and collaborate across functions to deliver measurable impact.
