Product Manager · SaaS Builder
Mezbah Uddin — I build, run, and grow SaaS products. Currently Product Manager at DigitaVision LTD, founder of Royal Subz.
I work in SaaS — running operations for a 200-product catalog by day, building and growing my own service on the side. Based remotely, working with teams worldwide.
Case Studies
Selected work
Royal Subz
A SaaS marketplace I built and launched solo — design, dev & infrastructure.
SEO: 0 to 39.9K
How I grew Royal Subz from zero search presence to 39,900 monthly impressions — no agency, no ad budget.
Support desk & AI agent
Replacing a locked-down SaaS helpdesk with a self-hosted Chatwoot on an idle VPS — then putting a sales bot in front of it that can only quote numbers the database just handed it.
About
I work where product, operations, and customer support meet.
At DigitaVision LTD I run a 200+ product catalog — managing inventory, uptime, and the live customer support that sits behind it. The work spans ops, product decisions, and cross-functional coordination on issue resolution.
On the side I built Royal Subz solo, end to end — design, frontend, backend, infrastructure, and SEO. It's how I keep my hands on the actual craft of shipping software.
B.Sc. in Electrical & Electronic Engineering from IIUC. Based in Bangladesh, working remote with teams across the US, UK, and Middle East.
