About

Small team, senior bar

Techzun is a freelance collective, not an agency, not a SaaS. Three engineers with 5+ years each, working as one unit when your roadmap crosses UI, APIs, mobile, AI, and data.

We started Techzun after seeing the same pattern repeat: great teams stuck between generic agencies that do not understand ERP and one-person freelancers who cannot cover the full surface area of a modern product. Our answer is a tight collective with overlapping skills and zero overhead roles.

We go deep on product engineering: architecture, integrations, and long term maintainability, whether that is a customer facing app, an internal platform, or automation that ties systems together.
