One person.
Many dimensions.
The interesting part of life happens between the labels. Pick a side to get to know me.
The maker mindset
Great software lives in the details.
I enjoy understanding the complete product: interface, data, business logic, integrations, and the people who use it. My work spans full-stack applications, SaaS platforms, payments, and AI-enabled workflows.

Beyond the keyboard
A guitar was just the beginning.
I've played guitar for 11 years and keyboard for 6. I also sing, play ukulele, and enjoy turning little ideas into recorded sessions using FL Studio, GarageBand, and Logic Pro.

Off the clock / On the stringsThe long way home
Some of my best ideas start outdoors.
I've ridden motorcycles for around 6–7 years. Road trips, trekking, driving, and exploring Bangladesh bring a different perspective to everything I build at my desk.

Where the road takes me02 / The journey
From client work to product ownership.
My path has moved from building individual features to owning how a complete product comes together. Select any chapter to read more.
Professional work began with WordPress plugins, themes, customization, and custom PHP applications. It was a foundation in problem-solving and making practical things for real people.
Working with Laravel, JavaScript, and React opened up more of the product stack. At Asian Group Italy, the work grew into integration-heavy systems and leadership across developers, design, and UI/UX.
At NexiBy LLC, I work on AI-powered software and SaaS products including Lupofy, Kbixy, and Webwatchly — from user-facing experiences to the systems behind them.
I'm also building Dokaneasy, a multi-tenant commerce platform with separate business workspaces, storefronts, custom domains, products, and orders. It's an opportunity to think like both an engineer and a product owner.
