“Tahmid is the best developer I have ever worked with. He has so much knowledge and expertise in so many different areas of development that you should make Tahmid your first choice.”
“Great communication, great expertise, great knowledge. A complex task exceeded expectations. I know I will get a quality outcome.”

A short call, then a written scope with timeline and price. No vague estimates.
Working software on a staging URL every week, with daily written updates.
CI/CD, monitoring and error tracking set up before launch day, not after.
Documentation, handover and an optional ongoing partnership.
Tralda is an independent software agency founded and led by Tahmid Alavi Ishmam — a small, senior, hands-on engineering team, seven years shipping production software.
No account managers, no outsourcing chain, no bait-and-switch. The engineers on your first call are the engineers who architect your system and write the code. Small and senior — that's the point.
Based in Bangladesh, working deliberately on your clock: real overlap hours with EU and Australian working days, and US East mornings covered. Daily written updates in clear English, so you always know exactly where your product stands.
For a defined product or feature set. Written scope, fixed price, fixed timeline — quoted within 48 hours of the scoping call.
For products that keep evolving. A committed monthly allocation of senior engineering — features, fixes, performance, infrastructure.
A 30-minute call: your idea, honest feasibility, and a clear next step. If we're not the right fit, we'll say so.
