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 built systems across their full lifecycle: on a payment platform supporting millions of dollars in annual volume for 20,000+ users, the Apple Pay / Google Pay wallet stack and Authorize.Net ACH billing end to end, plus the operations layer around them — reporting, alerting, automated failed-payment alerts, and scheduled donation summaries; KioskVisionAI, which watches 200+ donation kiosks across 60+ U.S. organizations with Azure Vision AI; and an automated Salesforce synchronization platform that eliminated manual CRM entry. Every product line shipped through CI/CD I architected — 7–8 zero-downtime production deployments a week.

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

  • Own the platform behind Partners.com.bd — Bangladesh's marketplace + business-social platform expanding into the UK — end to end: backend architecture, database, cloud infrastructure, deployment, scalability, and security across BD and UK operations.
  • Cut detail-page round trips from 3–4 to 1 (~70% fewer) by leading the legacy MVC → API strangler migration to a Clean Architecture .NET API — retiring the monolith with zero downtime while three Flutter apps (General, Executive, City) ship on top of it.
  • Closed the double-settlement money-loss path by construction: one generic payment ledger serving every paid feature, a vendor-agnostic gateway abstraction with country-aware resolution, and a self-healing settlement coordinator backstopped by Hangfire reconciliation.
  • Made background work crash-safe — no job silently lost or double-run — with a transactional SQL outbox, a dedicated Hangfire worker under a least-privilege SQL principal, a dead-letter queue, and idempotency keys.
  • Bounded CDN storage cost structurally: an async image pipeline whose server-owned lifecycle guarantees every orphaned upload is swept without client cooperation; also open-sourced the team's document-driven agent workflow as the d3 Claude Code skill.

Masjid Solutions — Software Engineer

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

  • On the team behind a donation platform moving millions of dollars a year for 20,000+ users, built the wallet-payment stack end to end — Apple Pay / Google Pay via Stripe Payment Intents, tokenized flows that improved mobile donation conversion — plus Authorize.Net ACH one-time and recurring billing.
  • Closed the loop on payment operations: reporting and alerting, an automated failed-payment alert system that surfaces silent recurring failures, and scheduled donation summaries delivered to admins and configured roles.
  • Cut onboarding time for new schools and memberships by 60% with automated data-import pipelines transforming raw Excel into validated SQL Server schemas, and built custom membership-registration forms organizations configure themselves.
  • Architected CI/CD for every product line (Bitbucket, Jenkins, IIS): 7–8 zero-downtime production deployments a week (350+ a year), dev environments cycling 20+ deploys weekly, all on rollback-ready backup strategies.
  • Put 200+ donation kiosks across 60+ U.S. organizations under intelligent watch by building KioskVisionAI — a distributed .NET 9 Aspire app on Azure (Blob Storage, Queues, Vision AI) with GitHub Actions continuous delivery.
  • Improved support response time with a Remote Kiosk Device Management System: REST APIs for live health (battery, Wi-Fi, uptime) and remote control (reboot, screenshot).
  • Eliminated manual CRM entry by building an automated Salesforce synchronization platform — daily jobs, custom field mappings, retries, and error recovery — and improved donor data quality by merging duplicates via Twilio Lookup enrichment.
  • Engineered across .NET (MVC & Core), SQL Server, Dapper, LINQ, and Entity Framework; contributed to the monolith-to-microservices migration with Clean + Onion architecture and domain-driven principles.

Masjid Solutions — SQA Engineer

October 2023 – November 2023 · Remote

  • Reduced regression bugs by 30% on a critical module by building a data-driven UI automation suite (C#, NUnit, Selenium, Serilog, Extent Reports) running in Jenkins CI — CSV-driven cases widened coverage without new code per scenario.

A1QA — QA Automation Engineer

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

  • Shipped automated regression and priority-based test suites run on every build/release — TestNG + Maven + Selenium WebDriver with CSV-driven data testing.
