About Me
Nearly four years of taking the work nobody else owns — anything that spans repos, products or cloud accounts.
Most of what I'm proud of started as somebody else's blocker.
The migration that touched three repositories. The cost line that wasn't in any sprint. The auth flow every product needed and none had written. I gravitate to the seams between systems, because that is where a team loses the most time.
I still write a lot of code, but the job has become making the estate predictable: fewer surprises, better alarms, and changes that customers never notice. Leading a team this size means the standards I hold in review matter more than anything I ship alone.
How I work
Inventory before plan
The migration that goes wrong is the one that missed a consumer. I list what reads a credential before deciding how to move it.
Fail open, alarm early
A guardrail that hides something alive is worse than none. Page on a leading signal rather than discover a lagging one at month end.
Boring is the goal
The best infrastructure work is invisible: migrations nobody notices, alarms that fire before customers do, budgets that stay flat.
Write it down
Runbooks a colleague can follow at 2 a.m., and updates a non-engineer can read. If it only lives in my head, it is not done.

What Colleagues Say
Recommendations from people I've worked with, quoted as they wrote them.
It is rare to find someone who combines technical excellence, a drive to learn, and strong character, and Emran has all three. I managed Emran when he worked on my team, and even then it was clear he was headed somewhere big. Seeing him grow into a Senior Developer and Team Lead has been one of the most rewarding things to watch in my career. … I would gladly work with Emran again, and I recommend him to any team looking for a talented engineer and an inspiring leader.
I’ve had the opportunity to work closely with Emran Hossain at Gain Solutions Ltd, where he currently serves as a Team Lead. Throughout our time working together, I’ve seen his strong technical capabilities, leadership, and commitment to the team firsthand. … What stands out to me is the combination of his technical expertise and leadership mindset. He not only focuses on getting the work done but also makes an effort to support his team, communicate effectively, and keep things moving in the right direction.
Emran is one of those rare colleagues you can completely trust to step into your shoes. When it was time for me to move on from my role as Team Lead, I knew the team had to go to him. He handled the transition flawlessly and has been doing a fantastic job leading everyone for the past nine months. He’s a natural leader, a great problem solver, and I highly recommend him for any leadership role.

Featured Projects
A selection of projects I've worked on throughout my career, showcasing my technical skills and problem-solving abilities.
MCP servers for Gain.io & Payrun
Backend | Jul 2026
Model Context Protocol servers exposing both products to AI assistants
- Built Model Context Protocol servers that let AI assistants query and act on live product data, with an OAuth consent flow and per-tool scoping so an assistant only ever sees what the signed-in user may see.
- Ported the implementation across both products from a shared core, keeping the tool contracts and auth model identical while accommodating each product's API differences.
- Covered the tool surface with an automated suite and verified every tool against live environments before release.
gain.io
Fullstack | Jan 2026 – Present
CRM platform — architecture, serverless backend and cloud estate
- Leading delivery of the CRM: contacts, calendar, bookings, deals, offers and email, built by incrementally porting proven modules onto a shared platform instead of rewriting from scratch.
- Own the serverless backend — GraphQL APIs across Lambda and ECS over PostgreSQL, with Google and Microsoft integrations for mail, calendar and sign-in.
- Own the cloud estate behind it, from per-environment isolation to the alarms that catch a runaway job before the invoice does.
payrun.app
Fullstack | Jan 2026 – Present
Payroll and workforce platform — localization, edge delivery and AI tooling
- Leading delivery of the payroll and workforce platform: time tracking, attendance, leave and timesheet reporting.
- Built the internationalisation layer across the web app and the TimeTrack desktop client, with translations pulled at build time so copy ships without a code change.
- Spans hiring through to payroll: careers pages and CV screening at one end, leave, expenses and reporting at the other.
easydesk.app
Backend | Dec 2024
Support desk — one inbox for email, live chat and social messages
- Support desk where email, live chat and social messages land in a single thread per customer, alongside a knowledge base, canned replies and satisfaction scores.
- Serverless from the outset, so a quiet workspace costs almost nothing to keep online and a busy one scales without a capacity conversation.
betterbangladesh.io
Backend | Aug 2024
Robust backend infrastructure with MongoDB integration and secure authentication
- Developed a robust backend infrastructure using Next.js and TypeScript, integrating MongoDB for data storage and JWT for authentication.
- Implemented file handling, dynamic file serving, CRUD APIs, and secure authentication/authorization mechanisms for efficient data operations and user management.
