Bengaluru, India

Trusted expertise. Delivery at scale.

Datalk is a technology partner for major government and institutional programmes. We help organisations plan ambitious work and see it through, from the first technical decisions to the systems people rely on every day.

  • Complete platform engineering Infrastructure, backend, web and mobile apps
  • Super Intelligence (SI) Automation and insight with human judgement
  • Deep data expertise Research platforms, statistics and analytics
  • Cost-efficient delivery Every decision weighed against the budget

What we believe

The bigger the programme, the more every decision matters.

Major programmes bring complex requirements, many stakeholders and real responsibility.

The technology behind them needs a clear plan, a solid foundation and a team that stays with it after launch.

Datalk brings all of that into one engagement.

Infrastructure, backend development, applications, analysis platforms and operational support are planned together, so the decisions made on day one still hold up on the day the system goes live.

Our government and institutional experience makes Datalk a grounded partner for programmes of national significance, and for ambitions that reach beyond India.

Delivery scope

One partner for the whole platform.

The complete platform

  1. 01Architecture and plan

    Objectives become an architecture and a delivery plan: what runs where, how it scales and what it will cost to operate.

  2. 02Cloud infrastructure

    Environments on AWS, Google Cloud or Azure, defined as code and run in containers, so they can be rebuilt, scaled and audited.

  3. 03Services and APIs

    Backend services and secure APIs hold the business logic and the data, with queues and caching where the load calls for them.

  4. 04Data and analytics

    Databases, pipelines and dashboards turn what the system collects into information people can analyse and act on.

  5. 05Web and mobile apps

    Accessible web and mobile apps, built on the same APIs, for the people who use them every day.

  6. 06Security, monitoring and support

    Access control, encryption, automated deployments and monitoring are built in across the platform, with a team that supports it for as long as it is in use.

Technology

Why Datalk

Confidence that comes from experience and clear ownership.

  1. Experience where the stakes are high

    We have built platforms for government and institutional programmes, where the technology has to meet specialist requirements and keep pace with a programme that is already moving.

  2. One point of accountability

    We take responsibility for the complete technical platform, so when something needs deciding or fixing, there is one team to call.

  3. Careful decisions about cost

    Scope, architecture and priorities are matched to the resources you have. The aim is a useful system that is easy to maintain and right for the programme's purpose.

  4. Support shaped by real operations

    Our work continues into live use. We have supported research platforms for the whole of their live period, including a national survey.

Scale and value

National reach. Global ambition. A practical plan.

Large programmes span many locations, several groups of stakeholders and a great deal of information. We start by understanding that context, then shape the technical approach around the scale you need, the budget you have and the order in which things have to happen.

Our Super Intelligence approach brings intelligent tools, domain knowledge and human judgement into that work. Each tool is used for a clear purpose and judged on what it actually achieves.

Research & Analytics

Analysis that leads to clearer decisions.

Alongside platform engineering, Datalk offers statistical analysis and advanced analytics for students, researchers and institutions. We connect the research question, the method and the interpretation, so findings can be understood and used with care.

Question, method, interpretation

  1. Research question

    What the study needs to answer

  2. Analytical method

    Suited to the design and the data

  3. Interpretation

    Understood and used with care

The research question decides the analytical method, and the method leads to an interpretation of the findings. The chart shows the method, not actual results.
