About Me.
Get to know me better
Full-stack Developer who ships product end to end
I'm Rajin Sakha, a full-stack developer who builds products from the interface down to the database. I work across React, Next.js and React Native on the frontend, and NestJS, PostgreSQL, Redis, background job queues and Docker on the backend.
My journey in software began 3 years ago as a frontend developer, and I've since grown into owning whole features: schema design, API endpoints, auth and integrations, then the UI that consumes them. That range covers e-commerce platforms, enterprise dashboards and AI-driven ad tooling.
Working across the stack means I can trace a bug from a slow page straight through to the query causing it, and design APIs that the UI actually wants to consume. I care about performance, accessibility and code that stays readable once the team grows.

Notes from production work
Building Conversion Tracking for Our Own Ad Network
Every test passed and the feature was completely dead. Four bugs from building a pixel, and why only a browser could find the worst one.
Migrating a Production Dating App from MongoDB to PostgreSQL
How 1.8 million documents, a 40-minute maintenance window, and four surprises taught me more than the plan did.
