Our Story

Built on real experience

Before Kosi Digital, our founder Deepak Kumar Jha spent over a decade building and scaling systems at some of the most demanding engineering environments in India and globally.

At HT Media / LiveHindustan.com, he architected backend systems serving 60 million+ monthly users — one of India's top-5 news platforms. At Radisys (now part of Reliance Jio), he built telecom IoT infrastructure for next-generation networks. At Publicis Sapient, he led enterprise engineering for large-scale retail and e-commerce platforms.

In 2024, he founded Kosi Digital with a simple thesis: startups and growing businesses deserve the same quality of architecture that powers the world's largest platforms — without the overhead of building a massive in-house team.

Today, we serve clients across North America, Europe, and the Middle East from our headquarters in India, delivering backend architecture, AI engineering, frontend modernization, and embedded engineering leadership.

Our Values

How we operate

Non-negotiable principles that guide every engagement

🏗️

Architect-Led Delivery

Every project is personally reviewed by our Technical Lead. We don't delegate critical decisions to junior developers.

🔒

Security First

GDPR compliance, encryption by default, and security best practices built in from day one — never as an afterthought.

⚙️

Technology Agnostic

We choose technologies based on your business needs and long-term maintainability, not vendor relationships.

🤝

Honest Communication

We tell you what you need to hear, not what you want to hear. If something won't work, we'll say so upfront.

How We're Structured

Architect-led, not architect-only

Every engagement is backed by a Technical Lead plus specialists across the stack
