At MASS DATA LTD., I built a multi-tenant SaaS platform for store and order management using ASP.NET Core, EF Core, SQL Server, and Angular. My work included courier integrations, bKash payment flows and merchant billing, plus inventory and stock ledger features.
I also worked on a Facebook Messenger inbox with live updates over SignalR and webhooks, and on a calling system with automated TTS calls and a browser web dialer. For an SMS and TTS calling platform, I built throttled background services and replaced read-modify-write balance logic with atomic updates.
Before that, at Prime Computers & Data Tech LTD., I developed hospital management and CRM software, working on frontend modules, forms, data tables, and backend API connections. I started there as an intern, working on Angular Material frontend components; I’m currently studying Computer Science Engineering at Bangladesh University.
