All case studies

Engineering ownership

We take responsibility for the system working, not for a list of tickets being closed.

Senior involvement

The people who design your architecture stay on it. You are not handed off after the sales call.

Technology flexibility

We work in your stack, or recommend one and explain the trade-off. No house framework you have to adopt.

Production mindset

Deployment, logging, backups and failure modes are part of the build, not a later phase.

Security & scalability

Access control, data handling and load behaviour get designed in, because retrofitting them is expensive.

Documentation & handover

Written architecture, runbooks and a handover that means another team could pick it up.

Long-term support

Maintenance, changes and new capability once the software is in real use.

Transparent communication

Direct access to engineers, plain status, and early warning when something slips.

More on how that works in practice: our engagement process, our security and compliance posture, and who actually builds your software. Not sure the fit is right? Five questions before you call will tell you in about ninety seconds.

• How much does custom software development cost?

  It depends on scope, and we would rather scope it than guess. Small, well-defined pieces of work start from around ₹25,000. A full product build runs to several lakh and upward, and long-term platform work is priced as an ongoing engagement. Tell us what you need and we will give you a range before you commit to anything.

• Can TantraDev build an MVP?

  Yes. MVP work is a defined service — a first version scoped to prove the idea works, built so it can grow rather than be thrown away. See our MVP development page for how we scope one.

• Can you work with our existing codebase?

  Yes. A lot of our work is on software someone else wrote. We start by reading the code and the infrastructure and telling you honestly what state it is in, what is worth keeping, and what it would cost to move forward.

• Can you develop both web and mobile applications?

  Yes — web applications, Android and iOS. Where a shared codebase makes sense we use React Native; where a platform needs native behaviour, we say so.

• Can you maintain an existing application?

  Yes. Maintenance and support is a standing engagement: fixes, dependency and security updates, small changes, and someone who knows the system when something breaks.

• Which technologies do you use?

  We are technology-agnostic. In practice we work most often with React, Next.js and TypeScript on the front end; Node.js, Python, Go and .NET on the back end; PostgreSQL, MongoDB and Redis for data; and AWS, Azure or Google Cloud for infrastructure. If your product needs something else, we will tell you whether we are the right team for it.

• Do you provide dedicated developers?

  Yes. A dedicated team works as an extension of yours — your process, your backlog, your standups — with the engineering standards and continuity of an in-house group.

• Can you help with cloud deployment?

  Yes. Cloud architecture, migration, deployment pipelines, infrastructure-as-code and monitoring, on AWS, Azure or Google Cloud.

• Do you work with startups?

  Yes. Early-stage work is usually an MVP or a first production version, scoped tightly so the money goes into proving the idea rather than into scope that has not been validated.

• Do you work with Indian businesses?

  Yes. We are based in Ravet, Pune and work with businesses across Pune, PCMC, Maharashtra and the rest of India — remotely, and in person where it helps.

• Do you work internationally?

  Yes. We work with clients outside India remotely. Our working hours are 10:00–19:00 IST, which overlaps the European morning and afternoon; calls with North American clients are scheduled early in the IST day.
