Every product we have built started as one sentence somebody said out loud.
We design and build web platforms,mobile apps and AI systems —then run them in production.
CodeBuzzers is a software development company in Kolkata. We work with founders, operations leads and enterprise technology teams — in e-commerce, fintech, real estate, on-demand services, education, food and grocery delivery — as their only technology team.

What brings people to us
- A manual process that has outgrown spreadsheets.
- A product that works but loses customers at a specific step.
- A platform built by someone else that nobody can safely change.
- An idea with a deadline and no in-house engineering team.
One team, one date, no surprises.
Every project runs the same five stages.
What we commit to
We tell you when something is a bad idea, before you pay to build it.
One date. If it moves, you hear it from us first, with the reason.
The person who scoped your project is still on the call in month six.
Nothing ships until it survives a bad network and a worse day.
Who owns what
You own
- All source code, in your own repository, from the first commit.
- Cloud accounts, domains, app store listings and every credential.
- Designs, source files and documentation.
- The right to take it to another team at any point, with no exit fee.
We own
- Delivery against the agreed scope and date.
- Code review, testing and security practice on everything we write.
- Uptime, monitoring and on-call under an SLA-driven support retainer.
- Telling you early when the plan needs to change.
50+ people, in one office, for over eight years.
Everyone who builds your product sits on one engineering floor in Salt Lake, Kolkata. The designers, engineers and delivery lead who scope the work are the same people who ship it and stay on it after launch.
We hire slowly. Nothing is subcontracted.
Who would be on your project
- Product designers
- iOS and Android engineers
- React and Next.js engineers
- Backend engineers
- AI engineers
- Cloud and DevOps engineers
- QA
- Delivery leads
Typical team: a product designer, the engineers your product actually needs, and one delivery lead who stays from scoping to handover.
