Dharshan

I'm a Full Stack Developer with 3 years of experience building production web applications using Node.js, Express, React, MongoDB, and REST APIs, backed by 1.7 years in technical support that shaped a strong debugging mindset. I focus on access control, data integrity, and concurrency-safe system design, and I'm comfortable across the stack, from React and CSS on the frontend to Node.js, Express, and database work on the backend, using Git for version control and CI/CD pipelines with GitHub Actions. Two achievements I'm proud of: At Cognizant Technology Solutions, I implemented role-scoped access control across 6+ user roles and multiple data domains on two platforms (Psilo and Pipeline Pilot), which reduced unauthorized edit paths by 35% and cut pre-production exposure of restricted records by 30%. I also resolved recurring cron-job concurrency issues under peak load using per-folder locking and job queuing, which eliminated data-corruption incidents and cut overlapping-execution issues by 40%. As a freelance developer, I closed a server-side price-validation gap on an e-commerce platform within 48 hours, cutting price-manipulation risk by 40%, and built a provider-agnostic payment adapter that reduced regional payment failures from 20% to under 2%. For my next role, I'm looking for a remote, full-stack position where I can keep working close to real user-facing problems, particularly around reliability, data integrity, and safe system design, on a small, collaborative engineering team where I can contribute across the frontend and backend and grow my skills in a MERN-style environment.
