Webanion is the software practice I founded in Dhaka in February 2021 and run full time as its software architect. It designs and builds AI-native platforms, multi-tenant SaaS and the infrastructure under them for founders and businesses in the UK, the US and Bangladesh: the data model and the backend, the web, mobile and desktop apps on top, and the Kubernetes cluster the production work runs on, which I operate myself. Its own products are part of the proof: this portfolio platform with its MCP server, and gm-libs, the library family every Webanion backend starts from.

Fully Booked is a booking platform for UK minibus and coach hire and the job-sharing network of operators behind it. I have built it since the first commit in April 2023: the React Native app on both stores, the customer booking website, the operator and admin dashboards, the Prebooked widget and the NestJS backend they share. From January 2025 I led its engineering as the product moved to a monorepo with gated releases, and since June 2026 I have been its CTO, after moving the whole platform to a self-hosted Kubernetes cluster with no recorded downtime.

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.

On Upwork I have worked directly with founders since December 2021, most of them at an early stage, taking products from the first idea and prototype through deployment and scaling across mobile, web and desktop. The profile is Top Rated with a 100% Job Success Score across 45 contracts; I earned Top Rated Plus along the way, and top 3% global performer recognition in 2024. The later work has been fewer, longer engagements with full product ownership, among them a UK booking platform taken from MVP to production across forty milestones.

At Edulog I worked as a software engineer on Athena, a cloud-native K-12 student transportation platform that helps school districts plan bus routes and trips and manage their fleets, from February to June 2026. I built new modules such as Field Trip Management, improved the admin dashboards, debugged complex issues, and worked on the integration between routing, mapping and the parent and driver portals, across backend services, cloud infrastructure and frontend interfaces.

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.
