Building AI-native systems — what comes after software
Hi, I am Abu Md Selim in my legal identity, but known as Mishu to most of you guys. The short version of who I am, what I value, and why the two halves of my career sharpen each other.
I’m a software engineer and entrepreneur who has spent the last eight years turning ideas into products people rely on every day. My work sits at the intersection of clean engineering and commercial thinking — I care as much about elegant architecture as I do about finding the market that makes it matter.
Today I lead Intactic, a workflow-automation company I founded in 2021. Before that I shipped fintech infrastructure used by millions, and learned the hard way that shipping is a habit — not an event. When I’m not building, I write about engineering leadership and mentor early-stage founders across South Asia.

Workflow automation for operations teams.
Founded in 2021 after one too many 2 a.m. spreadsheet incidents. Intactic automates the repetitive operational work that slows companies down — today trusted by 300+ businesses.
One-click checkout for emerging-market e-commerce.
Built the checkout layer local merchants actually needed — cash-on-delivery aware, mobile-first, and fast. Bootstrapped to profitability and acquired in 2020.
A learning platform for aspiring developers.
What began as weekend mentoring became a community of 25,000 developers taking structured, project-based courses in Bangla and English.

Tools I trust, wearing their official marks. Boring on purpose — the creativity goes into the product.
Investors, engineering leaders and mentees — the people who have seen the work from the inside.
Mishu is the rare founder who can debate product strategy at ten and pair-program on the fix at eleven. Our diligence team called his codebase the cleanest they had ever seen.
Occasional writing on engineering, entrepreneurship and the space between the two.
