Al-Insaf is a registered cooperative society in Monirampur, Jessore, providing fair microfinance and savings services to small traders. Founded in 2022, it runs member savings, loans and investor capital across branches, and moved that work from paper and spreadsheets onto a single auditable platform.

At WorkflowFiesta, I worked as engineering lead on an AI workflow automation platform, owning the product line end to end and directing a distributed engineering team. My work covered agent-driven workflow design, large language model integration across multiple providers, and durable orchestration for long-running jobs that resume rather than lose state on failure. I worked across a multi-tenant architecture with per-tenant isolation, contributing to feature delivery, performance work and the release process. I partnered closely with product and QA to turn complex automation requirements into reliable, maintainable systems.

At Edulog, I work as a full-stack engineer on Athena, a cloud-native K-12 student transportation platform. I develop and optimize scalable software that helps districts streamline bus routing, trip planning, and fleet management. My responsibilities include debugging complex issues, building new modules like Field Trip Management, enhancing admin dashboards, and ensuring smooth integration between routing algorithms, mapping systems, and parent/driver portals. I collaborate across backend, cloud infrastructure, and frontend interfaces to deliver efficient, reliable, and user-friendly solutions that improve operational efficiency, safety, and parent communication.

At TestFiesta, I work as a full-stack engineer improving reliability, performance, and overall platform quality for a highly asynchronous, distributed system. My role spans debugging complex issues across frontend rendering, Node.js services, PostgreSQL queries, and background workers, ensuring the platform runs smoothly at scale. I collaborate with QA and UI/UX teams to reproduce edge cases, refine user experience, and deliver consistent, high-impact fixes. In my first month, I helped resolve more than 50 major issues, strengthening system stability and elevating the product’s performance for end users.

I work at Rocksteady Technology as a full-stack engineer supporting major enterprise platforms like Edulog Athena and TestFiesta. I diagnose and resolve complex issues across frontend interfaces, backend APIs, distributed microservices, and Temporal-powered background workflows. I contribute to new feature development, performance optimizations, and architectural enhancements while collaborating closely with engineering, QA, and product teams to ensure high reliability and scalable system performance.

I have been leading Fully Booked as a solo full-stack developer since day one, building the platform entirely from the ground up. This includes cross-platform mobile apps for minibus operators using React Native with Expo, an admin dashboard built with React.js, a customer enquiry website, and a JavaScript booking widget that integrates into any external site. The backend is powered by NestJS and MongoDB, all deployed via Docker on DigitalOcean. The platform is fully scalable, performant, and designed for a seamless user experience
