"He brings a sense of ownership to every project that you simply can't hire for."

I highly recommend Mahbub as a software development lead. He is proactive, detail-oriented, and consistently ensures both technical and business requirements are clearly understood and properly executed. Mahbub is diligent about identifying and addressing issues early, even before they escalate into larger problems, which keeps projects on track and teams aligned. His ability to balance strong technical leadership with practical business awareness makes him a reliable and effective lead on complex projects. Beyond execution, Mahbub brings a strong sense of ownership to every project he leads. He communicates clearly with both technical and non-technical stakeholders, sets realistic expectations, and holds the team to a high standard without creating unnecessary friction.

"Mahbub is truly a life saver. He's honest, transparent, and efficient — and he cares that the code is actually good."

Mahbub is truly a life saver. His ability to take on challenging tasks and complete them in a sufficient timeline has been truly beneficial to the growth of our product. He is honest, transparent and efficient in his style of work. Many developers focus on just getting a task done. Mahbub focuses on ensuring all code is quality code so that when any other engineer is working on the platform, they won't have to freight confusion.

"I've worked with a lot of developers. Mahbub listens differently. He understands the problem, then solves it — not the other way around."

Mahbub is an experienced technologist with his expertise spanning beyond Software Engineering. At his core, Mahbub is a technical problem solver. Mahbub is able to carefully listen to and deeply understand a problem, and then reverse engineer his way into multiple optimal solutions. I've greatly enjoyed how he always brought my team and I into his process and we were able to reach success together. His technical prowess, problem solving skills, and collaborative working style make him a unique technologist. I'd work with Mahbub any day of the week.

"When provided with clear requirements, working with Mahbub is a seamless process. Minimal oversight required."

Mahbub is a highly capable full-stack developer with strong expertise in TypeScript and the ability to independently build and ship complete web and mobile applications. I managed Mahbub directly on a couple of projects, where he consistently delivered high-quality work across the full stack, including frontend, backend, and integrations. He is also very proficient with WordPress and Python, making him versatile across both modern app development and more traditional platforms. When provided with a solid Figma design and clear requirements, working with Mahbub is a seamless process — he translates designs into clean, reliable implementations efficiently and with minimal oversight.

WORKING TOGETHER

A call. A scope. Then I start.

If you are sourcing, email the resume and skip the call. If there is a product to ship, we talk first.

01

Call or email

30 min if we talk

Stack, the actual work, timezone overlap, and whether I can take it. If I cannot, I say so on the call. Recruiters: download the PDF or email mahbub@makereal.io.

02

A written scope

Before any code

What ships, what does not, and how we work. Price or monthly hours in writing. You see that before I start.

03

I join the repo

Contract or fractional

I take a slice: architecture, PRs, tests, deploy. Most teams keep me on after the first piece ships. Same person the whole way.

WHAT YOU GET

I don't staff the work.I do the work.

I join as a senior IC. Architecture, PRs, tests, security, deploy. I match the team's repo conventions and write things the next engineer can maintain. Make Real LLC invoices with a W-9. Code and IP transfer to you.

I

I am the person in the repo.

When you email, I answer. When production breaks, I fix it. No account manager in the middle. No junior seeing the codebase for the first time. Architecture through deploy is one person.

II

Production systems, not a demo.

TypeScript with a real backend, workers, billing, tests, and CI/CD. If the work includes AI, it is a pipeline with a job queue, not a prompt pasted into an API.

Rajshahi. Calendar is PT.

I overlap PT, CT, and ET. Same-day replies. Weekly notes you can forward. Full IP transfer. W-9 via Make Real LLC.

FIT

When I am the right hire.And when I am not.

Contract and fractional work with US companies through Make Real LLC. Useful for some teams. A waste of time for others.

This works if you...

  • Need a senior IC to own a slice: web, API, mobile, or AI
  • Hire contractors through an LLC — W-9, IP transfer, overlap with US hours
  • Want someone who has already shipped inside a product team, not only solo
  • Need tests, CI/CD, and a production deploy. Not a prototype.

Skip me if you...

  • Need a W-2 employee on US payroll, or a 10-person team in an office
  • Are shopping the cheapest offshore bid
  • Need someone in meetings most of the week
  • Need an agency with account managers

BEFORE YOU EMAIL

A few things I won't pretend.I mean them.
01
"I will not fake a timeline."

I cannot compress three months into a week. I move faster than a team with three hand-offs because I own the stack. If the work is three months, I will say three months.

02
"I use AI. I still write the architecture."

Models speed up the boring parts. They do not replace six years of shipping production systems, and they do not review the PR.

03
"I do the work myself."

I write the PRs. I do not hand them to a junior or a subcontracted shop. The person you screen is the person in the repo.

04
"I'm in Bangladesh. I work US hours."

Calendar is Pacific Time. I overlap PT, CT, and ET. Same-day replies. Written updates you can forward. I am not in your office.

COMMON QUESTIONS

Questions peoplealways ask me.

Recruiters, hiring managers, and founders — if it is not here, ask it on the call.

I take contract and fractional engagements through Make Real LLC — not W-2 employment. US companies get W-9 invoicing, a named senior on the work, and overlapping PT / CT / ET hours. If you need someone on US payroll in an office, I am not the hire.

I am based in Rajshahi, Bangladesh. The booking calendar is Pacific Time (PT). I overlap business hours across PT, CT, and ET — you are not waiting overnight for a reply. Same-day responses are the norm.

I join as a senior IC who owns a slice: architecture, PRs, tests, and deploys. I match the team's repo conventions, write things other people can maintain, and communicate in writing so hiring managers and founders can both follow along. I do not need a PM layer to stay unblocked.

Yes. Full source, full ownership, no licensing trap. Repos transfer to your accounts. Make Real LLC invoices with a W-9. Happy to put IP transfer in the contract in plain language.

Fair question. I have done this for six years and I do not take more than I can handle, which leaves margin. If something comes up, you hear from me immediately — not after a week of silence.

We talk before I go over — not after. I estimate impact on timeline and cost, we decide together whether to include it now or phase it. No surprise invoices. Unused retainer hours carry over.

An agency at $150–250/hr often staffs juniors and adds account overhead. A US FTE is right when you need a long-term seat on the team. I am the middle path: a senior who already ships production SaaS, AI, and mobile, overlapping US hours, at a rate that does not require a funding round — with full IP transfer when the engagement ends.

NEXT STEP

Resume, email,or a 30-min call.

Recruiters: download the PDF or email me. Founders: book 30 minutes. No pitch deck. Calendar is Pacific Time.
