A small studio with an engineering standard.
PROZEN is an independent technology studio based in West Bengal, India, working with businesses across India and overseas. We build automation, bots, websites, mobile apps and custom software — and we keep the team small on purpose.
Why this exists.
Most small businesses are offered two bad options: a cheap template that cannot do the job, or an enterprise vendor whose process costs more than the software. PROZEN exists in the gap between them — a studio small enough to quote honestly and technical enough to build systems that hold real operational weight.
We work on a small number of projects at a time. That is a constraint, not a marketing line: it is the only way the person who scopes your system is also the person who writes it.
Our practice is deliberately narrow — automation, bots, web, mobile and custom software. We do not take work we would have to subcontract to strangers, because that is where quality and accountability usually disappear.
Prosenjit Kar
Founder & principal engineer
Full-stack developer and systems builder working across Python, TypeScript, Android and Linux infrastructure. Builds the automation, backtesting and product systems that PROZEN sells — including the market widget, the quant engine and this site's enquiry pipeline.
Four rules we do not bend.
Scope before code
A written scope protects both sides. If it is not in the document, it is not in the quote.
Boring where it counts
We choose proven technology for anything holding money or records.
Honest answers
If a project will not pay back, we say so before you spend — including when the answer is a negative backtest.
Nothing hidden
You get the repository, the schema and the runbook. Leaving us should be easy.
What we are genuinely good at.
Automation & agents
Tool-using agents, retrieval over your documents, workflow orchestration, evaluation harnesses, cost control.
Product engineering
TypeScript and Python services, relational schema design, admin consoles, role-based access, audit trails.
Frontend craft
Design systems, accessibility, Core Web Vitals, animation that supports comprehension instead of decorating it.
Operations
Linux, nginx, TLS, backups, monitoring, deployment scripts and documentation someone else can follow.
