Building scalable, fast web applications - six years deep in frontend craft, and always exploring the things I never got to: new frameworks, new problems, new businesses, fun side projects.
I'm Subhra - a Senior Frontend Engineer with 6+ years building scalable web apps in JavaScript, TypeScript, and React, most recently at Wayground. I work on responsive UI, performance optimization, and the unglamorous details of code quality that make products feel calm - and I'm currently open to new roles and available to start immediately.
Along the way I've led projects across Hiver, Original4Sure, and Huawei - shipping AI reporting, automation modules, and performance wins, and mentoring developers to keep delivery maintainable. Outside of shipping product, I spend my time exploring the things I never got to: digging into new frameworks, fresh problem statements, and how new businesses work - then turning the best ideas into small, fun side projects.
Led a small team and shipped an interactive Hot Text quiz type, added localization and Sentry error monitoring, built an AI reporting system that turns natural-language queries into real-time automated insights, and lifted third-party LMS grade-sync accuracy from 94% to 99%.
Led custom fields, custom objects, connectors, and automation - a 9.2% ARR uplift. Cut extension failures from 10% to 0.8%, dropped load time 80% (20s → 4s), and piloted AI to shave 20% off timelines.
Built an anti-counterfeit widget that reduced fake goods by 80%, shipped a digital warranty tool with 1M+ registrations, improved legacy-widget Lighthouse performance by 35%, and launched the ChannelBLU MVP for 50,000 portal users in 30 days.
Built an internal AI training platform with 10,000+ monthly logins at 85% backend / 78% frontend coverage, and improved query efficiency of OpenLooKeng - an open-source big-data engine - by 10% via spilling.
Occasional long-form notes about frontend craft, the new frameworks and ideas I'm exploring, and the small disciplines that compound over a career.
A container is a process with a lie told to it about the filesystem, the network, and who else is running. Everything else is packaging. This is the whole working surface of Docker as it exists today - Compose v2 with no version key, BuildKit cache and secret mounts, buildx bake, compose watch, scout - as commands you can copy and the short answers to the questions people actually ask.
Quick peeks at what I'm reading and keeping close - the things that keep the engineer human.
I’d love to chat about frontend craft, career transitions, or design‑engineering - no strings, no pressure. Say pretty much anything.
