Software Development Company in Kolkata
The best Software Development Company in Kolkata, at the best available price.
You need engineering capacity that does not come with account managers, project managers and three juniors learning on your budget. One fixed monthly cost, senior people, any stack, and the person who takes your call is the person who writes the code.
Kolkata is the commercial centre of eastern India, with IT services concentrated in Salt Lake Sector V and New Town, and a business community long rooted in banking, microfinance, tea, jute, FMCG distribution and trading. Many established firms here are family or promoter run and adopt technology cautiously, often through someone they already trust, while lenders and microfinance institutions face the same RBI scrutiny as any bank in Mumbai.
Kolkata has a large pool of engineers in Sector V, but many experienced ones move to Bengaluru, Hyderabad or Pune. A dedicated senior engineer working remotely in your repository gives a local company steady senior capacity without depending on who stays in the city.
What you get
- Senior engineers only, on a fixed monthly cost with unlimited feature development rather than hourly billing
- Full stack: web, mobile, backend, data and the cloud infrastructure underneath it
- Your repositories, your cloud accounts, your credentials, throughout the engagement and after it
- Works alongside an existing integrator or in-house team rather than requiring you to displace either
- Month to month, because a team you cannot leave is just an expensive hire
Nothing payable upfront on project work: you pay per checkpoint, after you have seen it and accepted it. Retainers are month to month with no long lock-in. Scope and price are settled on a call.
Invoiced in INR, with GST as applicable.

You speak to the engineer who does the work. No sales rep, no deck.
Who builds here
On-Premise LLM Deployment
Kolkata's lenders and microfinance institutions hold sensitive borrower data, often collected in regional languages, and sit under RBI outsourcing rules. Keeping a model inside their own environment is usually the only way an AI project gets past the risk committee.
What Kolkata companies build with us
Get it built at $0.
That is not a discount. It is when you pay. The work is split into checkpoints with acceptance criteria written down before anything starts, and each checkpoint is invoiced only after you have seen it and accepted it. No deposit.
- $0 to start
- You hold every dollar until a checkpoint is delivered and you accept it. No approval, no invoice.
- Fixed cost, unlimited features
- Or hire the team outright: one fixed monthly cost, unlimited feature development, any stack.
- The engineer takes your call
- The person on your first call is the one who architects and writes it. No account managers, no bench time.
A US agency quotes $50,000 to $150,000 for the same build and asks for 40 to 50% of it before a line is written. Account managers, project managers, sales commission and bench time. None of it appears in your product.
Three stages, nothing hidden.
Twenty-minute call
We work out what capacity you actually need. Plenty of teams need one strong engineer for six weeks rather than an ongoing arrangement, and you will be told if that is your situation.
First month, scoped
A defined block of work with acceptance criteria written down before it starts, so you can judge the arrangement on delivered software rather than on a pitch.
Ongoing, month to month
A fixed monthly cost, direct access over Slack or WhatsApp, and no lock-in. You leave with the code, the documentation and the infrastructure, all of it already yours.
What actually applies here.
Regulation and data
Under the DPDP Act 2023 and the Digital Personal Data Protection Rules notified in November 2025, most obligations on data fiduciaries, including notice, consent, breach notification and data principal rights, are scheduled to take effect in May 2027, and the government has said it may shorten that window. For Kolkata's lenders, including microfinance institutions, the RBI Master Direction on Outsourcing of Information Technology Services and the 2023 Master Direction on IT governance, risk and controls set how a technology vendor may access and process borrower data, and digital lending is covered by the RBI's Digital Lending Directions. West Bengal promotes technology through projects such as the Bengal Silicon Valley Tech Hub and the fintech hub in New Town, which are infrastructure and incentive schemes rather than compliance rules.
Contracting and payment
Simple domestic contracting. Invoices in INR with GST as applicable, under a standard services agreement. No cross-border payment friction, no forex conversion cost, and no time spent on paperwork for an overseas supplier.
Working hours
Same time zone. I work from India on IST, so calls, reviews and replies all happen inside your normal working day.
Can an AI system work with documents in Bengali?
Yes, with care. Current open models handle Bengali text reasonably well for reading and summarising, but quality varies by task, so every project starts with a test set of your own documents and the results are measured before anything goes live.
Do you work with microfinance institutions and NBFCs?
Yes. Work is done under the institution's vendor and outsourcing process, with named, limited access, and where borrower data cannot leave its environment the model is deployed inside it, with every request logged for the institution's auditors.
Do you have a local office here?
No. You contract with an individual consultant based in India, which is exactly why the cost is what it is. If your procurement requires a locally registered supplier, we work as a subcontractor to your local partner instead.
How is this different from hiring an agency?
An agency bills you for a team and staffs it with whoever is free. Here there is no bench, no account manager and no sales commission in the price, and the engineer on your first call is the one writing the code. The trade-off is honest: you get depth from one senior person rather than breadth from five.
Can you work with our existing team?
Yes, and that is the usual arrangement. We take the parts your team does not have depth in, in your repositories and against your standards, rather than carving out a separate project nobody else can maintain.
