The Story
2020
No bootcamp. No CS degree. No family in tech. Just a laptop and the kind of obsession that doesn't have an off switch. Most people his age were figuring out high school. Rohan was figuring out how to get his first client.
2021
At 15, Rohan landed his first paying client. Then joined Damaska Digital Australia — a startup agency. He was handed projects and told to finish them. He did. Every single one. That agency is now one of the most recognised in Melbourne, Australia. He also opened a Fiverr gig. The world noticed.
2022
The NFT boom hit. Rohan built the platforms that ran it — 100+ blockchain and NFT projects delivered. One collection he built sold out in 24 hours and earned its founders $200,000. At 16, he became the youngest person in Bangladesh to earn Fiverr's Top Rated badge. Not by gaming the system. By outworking everyone in it.
2023
Awarded “Emerging Talent — Bangladesh” by the Fiverr community. By now, clients weren't just getting products — they were getting outcomes. Startups raised funding. Products got traction. 350+ projects. $150K+ earned. Clients across the US, UK, Australia, Canada, and Europe.
Now
He is currently building PaidInvoice.com. But Rohan still takes on a small number of client projects — for startups that want someone who thinks like a founder, moves like a developer, and ships like he's done it 350 times before. Because he has.
The Receipts
$1,000,000
Raised by clients after working together.
The products Rohan built helped startups walk into investor meetings with something real to show. Not a mockup. A working product. That's the difference between a pitch deck and a term sheet.
$200,000
Earned by an NFT collection. Sold out in 24 hours.
Built the entire platform — smart contracts, minting site, wallet integration. The collection went live. 24 hours later, it was gone. $200K in the founders' pockets.
350+
Projects shipped. Zero left unfinished.
Across SaaS, mobile apps, blockchain, e-commerce, and everything in between. Clients from the US, UK, Australia, Canada, Europe. Five years, no excuses.
$150K+
Earned as a freelancer. All organic.
No paid ads. No agency backing. Just a kid from Bangladesh and a Fiverr profile. Top Rated at 16. Emerging Talent at 17. $150,000 before most people graduate.
Services
01
Full-stack from scratch — auth, billing, dashboards, APIs. Built to scale. I've shipped enough of these to know what breaks at 10 users and what breaks at 10,000.
02
I'm building my own AI SaaS right now — so I'm not guessing at this. LLM integrations, intelligent workflows, AI features that actually make products better.
03
From idea to investor-ready product. The same playbook that helped clients raise $1M+. Designed, built, and shipped fast — without cutting corners that matter.
About
There are a thousand developers who will take your project, write the code you asked for, and hand it back. That's not what I do. I've shipped enough products to know what breaks at scale, what kills conversion, and what makes investors say yes. I bring that instinct to every project — not because I read about it, but because I've lived it across 350 builds. I work with startups who want someone who treats their product like it's their own. Limited spots. Real work. No shortcuts.
Open to projects
I take on a small number of projects at a time. If yours is ambitious and you want someone who's actually going to care about it — let's talk.
