M. Ashrafujjaman

Full-Stack Engineer

Ember.js, React & TypeScript on the frontend. Ruby on Rails on the backend.

About

I'm a full-stack engineer in Dhaka. At Corpovisuals I've shipped 25+ production Ember.js applications against Rails/JSON:API backends, including a national news platform and a four-app retail suite covering storefront, admin, customer care and outlet operations. I've also built production-grade Rails 8 applications for clients, working across the stack from PostgreSQL schemas to Hotwire frontends. For OniKanji, a US-based kanji-learning SaaS, I've built React + TypeScript features across the platform. What I care about: interfaces that are pixel-perfect on every screen size, backed by tests, shipped on schedule. Outside client work I build tools that scratch my own itch, most recently a RAG-powered trading journal in Python.
