Most studios can build what you describe.
Fewer will tell you when it is the wrong thing to build, and what to build instead.
We start with the buyer. Then we choose the technology.
Kordal Systems is a design and engineering studio. We build websites, web applications and AI systems for e-commerce brands and B2B companies, and we run software products of our own. Each piece of work is treated as a commercial problem before it is a technical one: who it is for, what they need from it, and what would count as it working.
That order matters. A site can be fast and still not sell. A tool can be well built and still not get used. An AI system can answer fluently and still not be trusted with real work. So the scope is written around the outcome, the design is tested against the objections of the people who will use it, and the stack is whatever serves both.
It also means saying so when a brief describes the wrong thing. A page that states what a product is not, a figure left unpriced because the document does not print one, a calculator that shows every step of its working: each came from asking what the work was for before asking how to build it.
How an engagement runsThree kinds of problem.
Products customers use
Brand and marketing sites, and the customer-facing tools beside them: what a business sells with, and what it is judged by before anyone has spoken to it.
Gemnye, a brand site for a US e-commerce seller · live on day six, the client’s figure · every account in the client’s name
About websitesSoftware a business runs on
Portals, dashboards, calculators and internal tools built for one job, where the spreadsheet has stopped coping and the off-the-shelf option does not fit.
Rateslip, a product of our own · supplier documents read from the printed page, put on one landed cost per unit · Kordal Labs: five tools we build and run in public
About web applicationsAI systems that can be operated
Agentic applications, MCP and API integrations and multi-step workflows, built with the permissions, evaluation and logging a team needs to run them, and with every answer traceable to its source.

About AI systems
How we think about the work
Ship the thing.
A portfolio of finished work beats a pipeline of interesting ideas. We would rather hand over something smaller that works than keep something ambitious unfinished.
Say what is true.
Every number on this site has a source: measured by us, or reported by the client and labelled so. When a claim cannot be supported, it does not go on the page. The same rule applies to what we build for you.
Built to be checked.
Hand it over properly.
Every account in your name, documented, with nothing that requires us to keep existing.
The whole outcome, not one layer of it.
A project is scoped, designed, built and handed over by one studio, to one standard. Nothing is lost between a strategy document, a design file and a codebase, because they are the same piece of work.
Every project has one accountable lead from the first call to the handover, and specialists are brought in where the work needs them. You are told who, and when.
- Product
- The business case, the requirements and the architecture: what is built first, what is left out, and what would count as it working.
- Design
- Interaction, accessibility and the visual system, built as tokens and components before any page is composed.
- Engineering
- The interface, the application logic, the APIs and data beneath it, and the deployment it runs on, with tests written as the work goes.
- AI systems
- Models, agents and tools connected to your own records, with retrieval before generation and every answer traceable to its source.
- Security and controls
- Identity and permissions, approval before any change, validation, evaluation and logs, each written down so your team can operate what we hand over.
- Research and evidence
- Who the buyer is and what they need to see, a source for every figure, and the assumptions written into the scope.

Amiya Bera leads Kordal Systems’ product and technical direction and works hands-on as a full-stack developer. His expertise spans product architecture, interface and design systems, application logic, APIs, databases, testing and production deployment. His technical work includes React, Astro, Next.js, TypeScript, Cloudflare Workers and Pages, and PostgreSQL. Rateslip, Kordal Labs and this website reflect his approach to designing, building and delivering production software.
His technical education includes training in artificial intelligence through IIT Patna, alongside extensive coursework and professional training from Google and Anthropic covering AI development, Claude, data and emerging technologies. He also holds an MBA in Marketing and has completed additional training in field and market research through programmes associated with the World Bank and the University of California, Davis.
Before founding Kordal Systems, Amiya spent more than thirteen years in B2B sales and market development with multinational companies, working across India, Southeast Asia and Africa.
