Junior Software Developer

Hello, I'm

Md. Toha
Siddique.

I turn complex requirements into dependable software.

I build and maintain production applications across mobile, backend and data layers—using Flutter, Go and PostgreSQL to solve operational problems in inventory, manufacturing, sales and supply-chain systems.

01 / Profile

Engineering across
the product stack.

I work from interface to database: designing clear Flutter flows, integrating APIs, shaping backend logic in Go, and keeping PostgreSQL data reliable.

My production work spans product receiving, warehouse storage, checkout, POS operations, reporting, live updates and performance improvements.

I also bring a strong foundation in data structures, algorithms and competitive programming, supported by hands-on research and embedded-systems experience.
