JoldiApp
Commerce · Co-founder
An ordering site I co-founded in Dhaka and took from zero to launch. Customers placed an order, and we went to the shops, bought what they asked for and delivered it. No warehouse, no inventory, just people doing the work while the software learned what people wanted.
Founder, engineer, and one of the delivery guys.
- Founder
- Engineer
- We bought it for you. Customers ordered, we went to the shops and delivered. This is the rider app.
- Riders, measured. Weekly income, delivered and cancelled counts, performance.
- Founder, engineer, rider. And one of the delivery guys. No warehouse, just people doing the work.
- Proof of delivery. Riders upload a delivery photo, for a safe handover.
pin_code_fields
Open source · Own package
A themeable PIN and OTP input for Flutter, MIT licensed. In production in thousands of apps, and the largest of the five I publish under my own name.
Nearly half a million downloads a month across five open source packages. 160 of 160 pub points.
- Author
- Maintainer
- Four shapes. One widget. Every colour, size and radius is themeable.
- A few lines to a working OTP field.
- 400K a month. Downloads in the last 30 days. The largest of five packages I publish.
- Same API, any look. Box, circle and underline cells from one widget.

How a project runs
From a rough idea to a live product. Worry-free.
Will it work, and what will it cost?
ttsalpha · 01 DiscoveryYou bring the problem. We work out the solution, map the infrastructure and optimise the cost, built to scale so it never needs a rebuild.
Will it take forever?
ttsalpha · 02 Estimate and buildEstimates come from the total effort with AI-accelerated work built in, so it moves much faster than a traditional dev shop. Reusable building blocks, each one replaceable on demand.
Will they go quiet on me?
ttsalpha · 03 See it every dayDaily updates, a demo every week, and a fresh build on staging every couple of days. You never wait to see where it stands.
Who looks after it?
ttsalpha · 04 After launchOne month of support free after launch, then a retainer that keeps it running and growing.
Proof, not promises.
“I saw how he started to learn Flutter when it was released, did not give up in spite of a lack of resources, and built his own modules. Today he is one of the dependable Flutter developers in the industry.”
“He showed his expertise from implementing pixel perfect user interfaces to complex logic for dynamic applications, on both Android and iOS.”
“One of the most inspiring CTOs I have had the chance to connect with. Open-minded, genuinely helpful, and highly resourceful.”

Starting fresh or stuck halfway
We bring products back to life.
Stalled, abandoned or breaking in production. We take it over, steady it and ship it again. Or we build it right the first time.
