About Me
A little about how I work
I’m Shamimul Haque — an Enterprise Software Engineer with 10+ years designing, building and leading the delivery of ERP systems and large-scale business applications. My work centers on software that powers real business operations: ERP platforms, inventory systems, workflow automation and enterprise portals that organizations depend on every day. I own the full lifecycle — translating complex business requirements into system architecture, leading development teams, and engineering for long-term...

Not a project dump — each one links to the problem, the trade-offs, and what shipped.
How I Work
Principles, not platitudes
I write the doc before the code when a decision is hard to reverse
If a decision touches more than one team or would take weeks to unwind, I write a short RFC first — even a half-page one. It forces me to notice the trade-off I'm about to hand-wave past, and gives other people a cheap way to disagree before it gets expensive to.
In code review, I look for the missing test, not the different style
I don't block PRs over formatting or personal preference — that's what a linter is for. I block them when I can't find a test that would catch the obvious way this breaks, or when the change quietly expands what a function is responsible for.
Tech debt gets a line item, not a feeling
When I take a shortcut under deadline pressure, I write down exactly what it costs and when it'll bite — not just "we should fix this later." That's the only way it competes for real prioritization instead of living as vague guilt everyone ignores.
On-call is a design review that happens at 2am
Every incident gets a blameless write-up, but the part I actually care about is the follow-up ticket: what would have made this page not happen at all. If the same class of alert fires twice, that's a backlog item, not bad luck.
Ambiguity gets one clarifying question, not a guess or a meeting
When a ticket is vague, my first move is to write down my interpretation and the assumptions I'm making, then ask the person who filed it to confirm or correct it in writing — not to guess silently or block on a meeting.
Leadership
Beyond my own tickets
Wrote the onboarding guide new backend hires now go through
MentoringAfter the third new hire asked me the same four questions in their first week, I wrote a getting-started doc covering local setup, our deploy process, and "who to ask about what." It's now part of the standard onboarding checklist and has cut first-PR time for new engineers from about two weeks to four days.
RFC: splitting the monolith's reporting workload onto a read replica
RfcProposed and drove the design review for moving analytics queries off the primary database after they'd caused two production incidents. Got sign-off from both the data team and infra, and the migration shipped with zero downtime.
Sat on the backend hiring bar for two years
HiringInterviewed roughly 60 backend candidates and co-wrote our system design interview rubric, pushing us to stop over-indexing on whiteboard algorithms in favor of questions closer to the actual job: reading an unfamiliar codebase and reasoning about a real trade-off.
Changed how the team shipped: PR size limits and a same-day review norm
ProcessOur review queue regularly sat for 3+ days, so big PRs rotted and people batched even more into them. I proposed a soft 400-line PR guideline and a same-day first-response norm; review turnaround dropped to under a day within a month, without anyone being told to "just review faster."

How I Can Help
ERP & Business Systems
Inventory, production, HR, and accounts as one system instead of five spreadsheets. Custom ERP modules built around how your business actually runs, not how the off-the-shelf vendor thinks it should.
Web Application Development
Custom Laravel applications built to last. Clean architecture, optimised performance, and code your team can actually maintain — from MVP to enterprise platform.
API Design & Integration
APIs that other systems can rely on. Clean REST design, token-based authentication with Sanctum or Passport, and third-party integrations — payments, CRMs, mapping — built with proper error handling and logging.

What people say
Shamim is an eager learner with a genuine hunger to grow. He was a student of mine, and even before graduating, he was already working in the industry as a freelancer — a sign of the initiative he brings to everything he does. I have found him technically far more advanced than many of his peers, with a strong grasp of concepts that goes beyond the classroom. I have no doubt he will continue to excel, and I wish him all the success in his career ahead.
Raihan Uddin Ahmed
Senior Lecturer, UWG
Before Wardrobe PLM, our business units ran on spreadsheets and email — costing and production drifted apart, and we caught margin problems only after the order shipped. Shamim built the ERP around our organisation, nesting five levels deep in some units and two in others, and insisted on getting that structure right before writing a single module. Nineteen modules now share one data layer, and merchandising, production and accounts finally work from the same numbers.
Md. Abdul Mozid Khan
Managing Director, Texeurop (BD) Ltd.
Shamim working for Texeurop as a Software Engineer from 1st April, 2016 to till date. Like all developers, he wrote code for computer software. His responsibilities included requirements gathering, analysis and design of complex Web applications using a variety of technologies. During the course of his employment, Shamim proved himself to be a dependable employee and a hard worker with solid problem solving and technical skills.
M. Zulfiker Ahmed
GM (Operation), Texeurop (BD) Ltd.
Shamim was a student in our Department of Computer Science & Engineering, and he stood out from early on for his curiosity and discipline. He didn’t treat his coursework as the finish line — he was already applying what he learned to real freelance projects before he even graduated, which speaks to both his initiative and his confidence in his own ability. As a department head, I’ve seen many students pass through our programme, and Shamim’s combination of technical depth and work ethic puts him among the more capable ones. I’m confident he will continue to grow and contribute meaningfully wherever he goes.
Al Imtiaz
Assistant Professor and Head, Department of CSE, UITS
Shamim is a student of mine, and one of the most capable programmers I’ve worked with. He combines technical depth with real work ethic — he takes time to understand a problem before building anything. I saw that firsthand on Wardrobe PLM, where he insisted on mapping actual organisational complexity before writing a single module, and the system has held up as a result. He learns fast, follows through, and takes ownership of what he builds. He’ll be a strong asset to any company.

I had the privilege of working with Shamim in IT team for more than one year at Texeurop (BD) Ltd. Shamim is proactive, result oriented, responsible and technically sound employee and he is always ready to put all his energy and time to get the job done. He has very impressive background and profile and I recommend Shamim as a programmer expert to connect with and consider for anything appropriate.

Shamimul Haque built our entire donation platform from scratch - Quick Donate, the Zakat calculator, live campaign pages for our emergency appeals, and support for bKash, Nagad, Rocket and SSLCommerz so donors could give however was easiest for them. For a charity, trust matters as much as the technology, and he understood that from day one. We're grateful to have him as our developer.
Md. Khairul Islam
Founder, Sab'a Sanabil Foundation
Shamim rebuilt our website from old static HTML pages into a proper Laravel site without losing a single search ranking - he mapped every old .html URL to redirect to its new page and added structured data so Google could actually understand we have offices in both Malta and Bangladesh. He delivered exactly what a growing company needs: something fast, clean, and easy to maintain.
Mohammad Iftakhar Islam
Founder, Euro GMP
Shamim gave each of our ten product categories — from denim to handicrafts — its own dedicated page instead of lumping them into one generic catalogue, plus a six-part 'Our Uniqueness' section that actually shows buyers our QC process and certifications before they ever book a sample. That's exactly the kind of site a sourcing agent needs to look as trustworthy as the factories we work with.
