Where I do the work.

The career path that lands at AI platform architecture. Nearly two decades of enterprise platform delivery and architecture ownership, now compounding into Principal-level direction-setting for LLM/RAG platforms, agentic AI, and cloud-native systems. The timeline below traces the full arc — from early .NET delivery in Dhaka to production AI platforms across the US fleet industry today.

    Enterprise Solutions Architect / Technical Lead Level I

    Holman · Remarketing Solutions

    Senior member of the cross-org Architecture Committee for the Remarketing Solutions, Supply Chain, and Fleet & Maintenance Engineering organization.

    • Designed, architected, and implemented the platform RAG framework powering 20+ production AI workflows — Azure AI Search (hybrid + vector) over SQL Managed Instance and Azure Storage, semantic caching on Azure Managed Redis, Azure OpenAI and Azure AI Foundry models, custom .NET orchestration on Container Apps and Azure Functions with Event Grid, behind APIM + Front Door under Zero-Trust/WAF.
    • Architected a real-time vehicle import pipeline with agentic AI — Event Hubs streaming ingest with agents that automate data extraction, validation, and enrichment at scale.
    • Built the LLM quality bar: golden datasets, groundedness/citation checks, regression gates, Azure AI Content Safety, prompt-injection defense, PII redaction, and human-in-the-loop approvals — zero compliance incidents.
    • Standardized AI-assisted engineering across 65+ engineers — GitHub Copilot custom agents (GPT and Claude models) for planning, implementation, review, bug fixing, and test generation.
    • Consolidated 150+ REST endpoints into a unified GraphQL gateway on .NET 10 behind Azure APIM with OAuth2 and field-level authorization.
    • Lead 6 Solutions Architects and 65+ engineers through cloud-native and agentic AI modernization; drove FinOps right-sizing and IaC — 25% cost reduction, 70% faster deployments, 80% lower rollback rates.

02 · Systems

Three architectures, drawn in motion.

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. (The enterprise RAG framework powering 20+ production workflows at Holman is described in Work above — its internals stay behind the firewall.)

SYSTEM 01 · HealthQCopilot

Agentic AI for Clinical Workflows

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.

Micro-Frontend Shell on Module Federation

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.

GraphQL Gateway Consolidation

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.

HealthQCopilot

Agentic AI for clinical workflows · open-source for humanity · 2025 – Present

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.

Bangla LLM

Independent open research initiative · 2024 – Present

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.

I’m currently exploring remote and hybrid Forward Deployed Engineer and Principal / Enterprise / Senior AI Architect roles where production LLM delivery, cloud-native platform thinking, and pragmatic engineering leadership compound. AI-native product companies, PE-backed SaaS, fleet / logistics, and fintech feel most aligned. Authorized to work in the U.S. — no visa sponsorship required.
