I build business-critical web applications end to end — robust Laravel backends, complex financial & multi-tenant workflows, and intuitive Vue.js interfaces that scale.
Engineering business-critical systems with precision.
I’m a Software Engineer at Softzino Technologies in Uttara, Dhaka, with 4 years of experience building business-critical web applications. I work primarily with Laravel and PHP on the backend alongside Vue.js, Inertia.js, and TypeScript on the frontend, designing reliable systems that support real operational needs.
I have architected financial workflows for enterprise accounting (Accounts Payable, Receivable, General Ledger, Chart of Accounts), built multi-tenant HRMS modules with AWS KMS multi-layer encryption & 2FA, and led backend engineering for platforms serving 10,000+ registered users and 5,000+ mobile app downloads. Outside work, I have a deep foundation in Competitive Programming with 1,500+ solved problems and published deep learning research at ICCIT 2024.
