About
I'm Deepak Jha — Principal Solution Architect and Founder of Kosi Digital. With 15+ years of engineering experience, I help startups and enterprise teams design backend systems that scale to millions of users.
I write about system architecture, Node.js, microservices, AI/LLM integration, cloud infrastructure (AWS/GCP), and the real-world lessons from building systems that serve 60M+ users.
Currently building: Kosi Digital (architecture-led engineering firm), WorkHire (enterprise bulk hiring SaaS), and MegaExam (edtech platform).
I share honest, battle-tested insights — not hype.
Available for
Fractional CTO engagements, architecture reviews, technical consulting, conference talks, and content collaboration on system design, AI integration, and scalable backend engineering.
