Building HealthQCopilot — an agentic AI healthcare platform on Azure with Semantic Kernel, Phi-4-Medical, and FHIR. Nearly two decades scaling enterprise SaaS across healthcare, fleet, trade finance, and government, and serving on the Architecture Committee at Holman.
The career path that lands at cloud and AI platform architecture. Nearly two decades of enterprise platform delivery and architecture ownership, now compounding into Principal-level direction-setting for agentic AI, micro-frontend, and cloud-native systems. The timeline below traces the full arc — from early .NET delivery in Dhaka to platform architecture across the US fleet industry today.
Senior member of the cross-org Architecture Committee for the Remarketing Solutions, Supply Chain, and Fleet & Maintenance Engineering organization. Co-own multi-year platform strategy for the systems that power 300+ enterprise fleet clients and roughly one million transactions per day at 99.95% uptime on Azure Container Apps, Service Bus, Cosmos DB, and Azure APIM.
Delivered Azure solutions for 100+ fleet clients on IaaS, with ARM/Bicep, TeamCity, and Octopus Deploy automation that cut deployment time. Pioneered Dapr adoption for cloud-native vehicle remarketing across North America. Mentored junior engineers across the .NET, Azure, and JavaScript stacks.
Led architecture and delivery of API-based services for ARI Vehicle Remarketing on .NET 6, Dapr, and Azure Container Apps. Built micro-frontend React platforms via Webpack 5 Module Federation for mobile and desktop, on an Onion/microservices architecture.
Architected API services for ARI Vehicle Remarketing — offers, vehicle sales, and 3rd-party integrations on .NET Core, EF Core, IdentityServer4, and Oracle. Built React/Redux and Angular 11 client apps (Module Federation), a SignalR/Hangfire tracking platform, and an Electron-based proctoring application.
Solutions architect and technical lead managing multiple teams across mobile, web, and API services for delivery, trading, and photography products. Architected cloud API services on .NET Core, CQRS, RabbitMQ, and microservices with Onion architecture.
Technical lead for a cloud-based SaaS tax-automation platform integrated with Malaysia's tax authority (LHDN), serving UEM Group, Tan Chong, Boustead, and tax agents nationwide. Built on C#, ASP.NET, CQRS, and microservices over Azure cloud web roles.
Led architecture for offline-capable mobile and responsive web applications (AngularJS, Ionic, PhoneGap, ASP.NET MVC) and product localization frameworks. Drove R&D, tooling decisions, and team mentoring.
Architected responsive and offline-supported web/mobile applications (ASP.NET MVC, Knockout.js, PhoneGap, Snap.svg) and localization frameworks. Led and mentored delivery teams across versatile technology stacks.
Technical project manager and architect for access-control, document-management, and code-generation (VOOT) products in .NET. Designed distributed integrations, WCF/WPF self-hosting services, and the online reservation engine for Sayyar Online (60,000+ customers, 1M+ contracts).
Built Outlook/Office client software (VSTO, WCF) and WPF/ASP.NET media tools. Implemented n-tier architecture with custom localization, logging, exception-handling, and security layers in C#.
Developed n-layer .NET web workflow systems — logging and data-access application blocks, ASP.NET Membership security, and Infragistics/AJAX presentation layer.
Architected .NET web-service/SOAP integrations and a database-driven application framework. Led FAST (Field Force Automation & Sales Tracking) — J2ME mobile clients with ASP.NET sync services for domestic and international pharma and FMCG clients.
The HealthQCopilot agentic AI platform, a Module Federation micro-frontend shell, and a generic GraphQL gateway reference pattern. Hover the nodes — each one has a note about what runs inside.
A HIPAA-grade agentic platform built on .NET 10 and Semantic Kernel. A patient encounter — voice plus structured intake — is routed through five specialised agents around an orchestrator: triage, clinical coding, prior authorization, care-gap detection, and a hallucination guard that verifies every output against the patient’s FHIR record before it reaches the EHR.
The pattern for splitting a monolithic React app into independently deployable remotes. A thin shell host owns routing, auth, design system, and telemetry; each remote ships its own Vite/Webpack bundle, exposed at runtime via Module Federation. Independent teams, independent deploys, one cohesive product.
The pattern I’ve used to collapse fragmented REST surfaces into a single governed schema on .NET + HotChocolate behind Azure APIM. OAuth2 with field-level authorization through GraphQL directives, edge throttling at APIM, and event-driven services behind the gateway.
Nearly two decades of compounding depth across cloud, distributed systems, and now agentic AI — the cards below are the narrative; the matrix below them is the searchable index.
Two long-running ventures alongside the principal role — both released under permissive open-source licenses so the work compounds beyond any single employer or geography.
Healthcare is too important to lock behind a single vendor. HealthQCopilot is being released as open source so any hospital, clinic, or public-health agency — not just well-funded systems — can deploy HIPAA-grade agentic AI on their own infrastructure.
Built on .NET 10 and Semantic Kernel: an ambient scribe captures the encounter, five specialised agents reason over it (triage, clinical coding, prior-auth, care-gap, and a hallucination guard), and every output is verified against the patient’s FHIR record before it reaches the EHR. Nine microservices behind a YARP gateway and GraphQL BFF.
Independent research building Bangla-language LLMs for social-impact applications — including migrant-worker protection and education access. Closing the gap for one of the world’s most-spoken but most-underserved languages in foundation models. Data, evals, and model weights are being released openly so other Bangla-speaking communities can build on top.
Pieces I publish from the architecture work. Each one starts with a failure, then the fix.
Why a hallucination guard against FHIR became the most important agent in the system, what we got wrong about prior-auth, and the orchestration patterns that survived contact with real clinicians.

I’m currently exploring remote and hybrid Principal / Staff Architect roles where cloud-native platform thinking, enterprise AI, and pragmatic engineering leadership compound. PE-backed SaaS, fleet / logistics, fintech, and AI-platform companies feel most aligned. U.S. Permanent Resident (Green Card holder) — no visa sponsorship required.
