Builds Systems.
7 years building production MERN applications — started backend, went deep on React. From REST APIs to pixel-perfect UIs, I build things that scale.

— About Me
The engineer behind the code
Hi, I'm Devashish — I've spent 7 years shipping full-stack systems that scale.
I started as a JavaScript trainee in 2018, went deep into Node.js and backend systems, then expanded into full-stack and frontend-heavy roles. Over 7 years I've shipped across healthcare, fitness, food delivery, and enterprise workforce platforms.
My stack is the MERN ecosystem — Node.js APIs, MongoDB schemas, React interfaces, and real-time layers built with Socket.io and PubNub. I've also worked with PostgreSQL, MySQL, and pgvector for projects that needed relational or vector-based storage.
I’ve contributed to products across workforce management, mental health, and interactive platforms — collaborating closely with cross-functional teams and mentoring engineers along the way. I'm based in Rajasthan and open to remote-first opportunities globally.
Technical Skills
How I work
Systems thinker
I think in APIs, schemas, and data flows before writing a line of code. Architecture decisions made early save weeks later.
Code quality
Every function named clearly, every API documented, every PR reviewed. I treat the codebase like a product — it should be maintainable by anyone.
Cross-functional collaborator
I have worked with design, product, and backend teams across 3 companies and 6+ production projects.
Continuous learner
From JS trainee to senior engineer — I have always pushed into new territory, currently exploring AI/ML and OpenAI APIs.
