03 What we do
Our services
01
Mobile Product Engineering
Native Android and cross-platform Flutter, shipped to Cafe Bazaar, Myket and Google Play. Multi-flavor builds, signed release automation, and clean-architecture codebases that survive multi-year maintenance windows.
Proof 02Backend Systems & APIs
Service-oriented backends behind live consumer traffic. Typed contracts, background workers, queue-driven pipelines, and observability baked in from day one.
Proof 03Cloud Infrastructure & DevOps
Infrastructure treated as product. Reproducible environments, gradual rollouts, and the boring reliability work that only pays off in year three.
Learn more 04AI & LLM Product Integration
Persian-first assistants and generative features on top of frontier models. Token accounting, model routing, safety layers, and a monetization model that survives a viral spike.
Proof 05UI Design & User Experience
Design systems built for the Persian and Latin scripts together. Typography, motion and information density decided once and defended everywhere.
Learn more 06Product Operations & Reliability
The unglamorous half that keeps apps alive for years. Every product is operated by the same people who built it.
Proof Also from Kahroba Earlier chapters of our work — still serving users today.

05 Open source
Libraries we maintain in the open
Free, Apache-licensed, pure-Java. Source lives on GitHub — use it, break it, send patches.
Gahshomar
A pure-Java library for Persian, Hijri and Gregorian date conversion.
A Java library that gets Persian dates right. Convert between the Shamsi, Gregorian and Hijri calendars with correct leap years, format numbers the Persian way, look up Iranian holidays, and get automatic DST handling for Tehran time. Lightweight, no external dependencies, production-ready.
- Zero external dependencies
- Convert Shamsi ↔ Gregorian ↔ Hijri
- 133+ automated tests
- Iran timezone + DST built-in
LightDI
A lightweight, annotation-based dependency-injection framework for Java.
A minimal dependency-injection framework for Java. Under 50KB, no external dependencies, clean and readable source. Alternative to Spring/Guice when you need something small — embedded runtimes, learning, or projects that just don't want the full ceremony.
- Under 50KB, zero dependencies
- Constructor, field & method injection
- Automatic bean lifecycle & scoping
- Clean, readable source — great to learn
