About

I work where production engineering meets machine learning research — connecting business operations, software architecture, AI, payments, and cloud infrastructure into systems that run every day.

Today I lead Web & App Development at Partners Online (Bangladesh & UK), the company behind Partners.com.bd. I design and run the platform end to end — a .NET API, the Flutter apps, and a legacy MVC→API migration — deploying constantly and designing with DDD, vertical slice, and clean architecture principles so the systems stay healthy long after they ship.

Before that, at Masjid Solutions, I owned systems across their full lifecycle: payment infrastructure (Stripe, ACH, Apple Pay, Google Pay) supporting millions of dollars in annual volume for 20,000+ users; KioskVisionAI, which watches 120+ donation kiosks across 60+ U.S. organizations with Azure Vision AI; and an automated Salesforce synchronization platform that eliminated manual CRM entry — roughly 200+ releases a year through CI/CD pipelines I architected.

The research thread runs in parallel: my undergraduate thesis explored quantum machine learning — variational circuits, encoding methods, hybrid classical-quantum models on PennyLane simulators — and continues through my MS: Bangla POS tagging with knowledge distillation, multi-output CNNs, ensemble methods.

My mission: continuously improve systems, automate the repetitive, and innovate at scale.

Experience

Partners Online (Bangladesh & UK) — Operation Manager, Web & App Development

March 2026 – Present · Dhaka, Bangladesh (Remote · part-time) · No Borders IT / Partners Online BD & UK Ltd

  • Lead Web & App Development for Partners.com.bd — Bangladesh's marketplace + business-social platform, expanding into the UK — owning backend architecture, database, cloud infrastructure, deployment, scalability, and security across BD and UK operations.
  • Design and build the product's rebuild end to end: a .NET (Clean Architecture) API, three Flutter apps (General, Executive, City), and a legacy MVC → API migration.
  • Shipped a transactional background-job system (dedicated Hangfire worker, SQL outbox, dead-letter queue, idempotency) and a document-driven agent workflow (open-sourced as the d3 Claude Code skill) that keeps the codebase AI-navigable.

Masjid Solutions — Software Engineer

December 2023 – May 2026 · Indianapolis, Indiana, USA (Remote)

  • Engineered backend systems with .NET (MVC & Core), SQL Server, Dapper, LINQ, and Entity Framework powering Islamic schools, memberships, events, and donation management.
  • Designed automated data-import pipelines transforming raw Excel into validated SQL Server schemas — cutting onboarding time for new schools and memberships by 60%.
  • Architected CI/CD with Bitbucket, Jenkins, IIS, and rollback-ready backups — zero-downtime deployments across dev, beta, staging, and production.
  • Built KioskVisionAI, a distributed .NET 9 Aspire app on Azure (Blob Storage, Queues, Vision AI) with GitHub Actions deployments for intelligent kiosk monitoring.
  • Built a Remote Kiosk Device Management System — REST APIs for live monitoring (battery, Wi-Fi, uptime) and remote control (reboot, screenshot), improving support response time.
  • Integrated Stripe + Authorize.Net ACH recurring payments, and Apple Pay / Google Pay via Stripe Payment Intents — tokenized wallet flows that improved donation conversion.
  • Implemented Twilio Lookup API data enrichment to merge duplicate donor records, significantly improving data quality and reporting accuracy.
  • Contributed to monolith-to-microservices migration: Clean + Onion architecture, repository patterns, domain-driven principles.

Masjid Solutions — SQA Engineer

October 2023 – November 2023 · Remote

  • Built a data-driven UI automation project (C#, NUnit, Selenium, Serilog, Extent Reports, Jenkins) automating test cases in CI/CD.
  • Automated a critical module's regression suite — 30% fewer regression bugs, more stable release cycle.

A1QA — QA Automation Engineer

November 2022 – July 2023 · Colorado, USA (Remote)

  • Developed automated test scenarios with TestNG + Maven + Selenium WebDriver.
  • Implemented CSV-driven data testing for regression and priority-based suites per release.
