01Work

Selected work, in depth.

Client work is described generically — the architecture, decisions and reasoning — and names the client only where they have agreed to it.

SaaS backend · Cloud marketplaceShipped to production

Licensing & Entitlement Platform

1The problem
A cloud marketplace sells the add-on, but something has to decide what each buyer may run — online, offline, behind NAT or during a vendor outage.
2What I built
Morsalin led the design and did the coding: one Go service with a Vue operator console that provisions purchases, signs licenses and answers entitlement checks.
3What happened
Shipped to production. Licenses verify offline, so a vendor outage never stops a paying customer, and support moved from engineering to audited operator actions.

AI Listing Pipeline for a Luxury-Watch Auction House

1The problem
Two watch dealers supply inventory in incompatible shapes — a scraped storefront, a live availability feed and spreadsheets that change between deliveries.
2What I built
Morsalin designed and built a Laravel pipeline that merges the sources, hosts every photo on a CDN and has an LLM write each listing under strict, validated rules.
3What happened
In use since May 2026: 1,027 AI-written listings and 27 upload-ready catalog exports. Cataloging moved from writing to reviewing.

photos hosted: 3,669

AI Cataloging System for Fine-Jewelry Auctions

1The problem
Suppliers describe their jewelry in spreadsheets of raw specifications; every row has to become a publishable auction lot with photos, copy and taxonomy.
2What I built
Morsalin designed and built a FastAPI and Celery system with two Gemini stages on Vertex AI — a vision “gemologist” and a copywriter — bound to a 335-term vocabulary.
3What happened
Shipped in 2025. Staff upload a file and review finished lots, and the model is never allowed to invent stone counts, carats or metal purity.

WordPress Hosting Control Panel

1The problem
Customers want WordPress on their own cloud account — their server, their bill — without learning to run a Linux server.
2What I built
Morsalin, as sole engineer, built a panel that provisions servers on five clouds and runs them through a signed Python agent, plus a Google Cloud Marketplace edition.
3What happened
v1 shipped February 2025. Sites, SSL, PHP, databases, backups and WordPress itself are run from the browser, with Stripe billing on top.

Anti-Piracy Video LMS

1The problem
Paid, recorded courses lose their value the moment a video is shared or an account is passed around.
2What I built
Morsalin designed and built a Laravel platform with DRM streaming, watermarks unique to each viewer, location-aware access, single-device sessions and a real-time admin.
3What happened
In use from 2021 to 2023. Any leaked recording traces back to one student, and course access matches how courses are sold — at a center, at home, or both.

03FAQ

Questions clients ask first.

Does MD Morsalin take contract work?

Yes — part-time or contract only, not full-time. MD Morsalin is a contract software engineer based in Dhaka, Bangladesh who works remotely on US Eastern Time — fixed-scope builds, monthly retainers and architecture reviews. Email [email protected] with what you are building.

Who can build a WordPress hosting control panel that provisions servers on several clouds?

MD Morsalin built one alone over three generations: a self-serve SaaS that provisions servers on Google Compute Engine, AWS Lightsail, DigitalOcean, Linode and Vultr and manages them through a signed Python agent, plus a licensed Google Cloud Marketplace edition. Case study: https://morsalin.online/work/wordpress-hosting-panel

Has MD Morsalin built AI systems that run in production?

Yes. An LLM listing pipeline for a luxury-watch auction house has written 1,027 validated listings since May 2026 (https://morsalin.online/work/listing-pipeline), and a two-stage Gemini vision system on Vertex AI turns supplier spreadsheets into fine-jewelry auction lots (https://morsalin.online/work/jewelry-cataloging).

Can MD Morsalin build a licensing backend for software sold on a cloud marketplace?

He led and coded one that is in production: a Go service that provisions marketplace purchases, signs ed25519 licenses that verify offline, and encrypts sensitive columns with zero-downtime key rotation — backed by 654 Go tests. Case study: https://morsalin.online/work/licensing-platform

Has MD Morsalin built a video platform that prevents piracy?
