MD Morsalin
Contract software engineer — SaaS, cloud infrastructure & AI
I design, build and run SaaS platforms, cloud infrastructure and AI pipelines end to end — as a contractor for your team. Eleven years in, I'm still happiest when a system gets quieter, faster, and cheaper all at once.
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.
Licensing & Entitlement Platform
A production licensing backend for a cloud marketplace. The marketplace sells the add-on; this service decides what the buyer is entitled to, signs the license, and answers the software that asks whether it may run — online, offline, behind NAT, or with no internet at all.
AI Listing Pipeline for a Luxury-Watch Auction House
Two dealers supply the watches — one through an online store and a live availability feed, one through spreadsheets that change shape between deliveries. This pipeline brings both together, hosts every photo on a CDN, has an LLM write a constrained auction listing for each watch, and exports an upload-ready catalog.
AI Cataloging System for Fine-Jewelry Auctions
Suppliers describe their jewelry in spreadsheets of raw specifications. This system turns every row into a publishable auction lot — photos mirrored to the house’s own storage, images examined by an AI gemologist, copy written by an AI specialist under the house’s rules, and everything mapped to the auction platform’s taxonomy for bulk upload.
WordPress Hosting Control Panel
A self-serve SaaS for running WordPress on your own cloud. A customer connects a cloud account; the panel creates the server, installs a tuned LEMP stack and a management agent, and from then on runs the site, SSL, PHP, database, cache, backups, files, SSH and WordPress itself from the browser — with Stripe billing on top.
Start from where you are.
Fixed prices, written scope, a proper handover. Pick the sentence that sounds like you.

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?
Yes — a Laravel learning platform for paid courses with DRM streaming, forensic watermarks unique to each viewer, location-aware access and single-device sessions, so a leaked recording traces back to one student. Case study: https://morsalin.online/work/anti-piracy-video-lms
Which cloud platforms does MD Morsalin work with?
Google Cloud first — he completed two Google Cloud specializations on Coursera in 2020 (Architecting with Google Compute Engine, and Preparing for the Cloud Engineer certification) and holds nine Google Cloud skill badges, including Terraform, load balancing and monitoring (https://www.credly.com/users/morsalin1342/badges) — plus AWS, Azure, DigitalOcean, Linode, Vultr and Alibaba Cloud.
