Service · Web application development
Software you will still be running in five years.
Who can build a custom web application or SaaS product in Sri Lanka?
We design and build multi-tenant web applications end to end — database, API, front end, hosting on AWS — and we run one ourselves, which is the difference between a vendor and a builder. Sevo Biz App is the reference: the same team, the same standards.
What you receive
Things you can point at.
- Requirements written down as the screens and the rules they enforce, before a line of code
- A PostgreSQL data model with per-tenant isolation where more than one company will use the system
- An API (Java/Spring or Node) with automated tests, and a React/Next.js front end that works on a phone
- AWS hosting with infrastructure as code, CI/CD, backups and monitoring — in your account
- Documentation a second developer can pick up, and a handover that does not depend on us
How it runs
Four steps, in this order.
- 1
Discovery
The business process as it is, then as it should be. Screens sketched, rules listed, edge cases named.
- 2
Foundation
Data model, authentication, tenancy and deployment pipeline first — the parts that are expensive to change later.
- 3
Slices
Working software every one to two weeks, each slice usable on its own and demonstrated on the real environment.
- 4
Handover
Runbook, architecture notes, tests green in CI, and your team able to deploy without us.
What it costs
How the number is arrived at.
A written quotation follows a first conversation, usually within one working day, and it is the number that governs the project: fixed for the agreed scope, with changes priced before they are done rather than discovered on the invoice. A published price guide for this service is being prepared; until it is here, the fastest way to a figure is a message describing what you need.
Why us
We do this for our own products first.
Sevo Biz App is the proof: a multi-tenant system with an offline point of sale, a stock ledger, double-entry accounting and an AI module, built and run by this team on AWS. A vendor shows you a portfolio; we can show you the product.
Questions
Asked before hiring.
What stack do you build with?
Java 21 with Spring Boot or Node.js for the API, PostgreSQL, React with Next.js for the front end, and AWS (Lambda or containers, S3, CloudFront, Cognito) for hosting — the same stack Sevo Biz App runs on. We choose within that set for the job rather than starting from a blank page every time.
Who owns the code?
You do, from the first commit, in a repository and an AWS account in your name. We work in it; we do not hold it.
How long does a typical application take?
A focused internal tool is usually six to ten weeks to first production use; a multi-tenant product is longer and delivered in slices, each of which works on its own. The quotation states the slices and their order.
Can you take over an existing system?
Yes. The first engagement is usually an assessment — what it does, what it costs to run, where it is fragile — written up so you can decide whether to extend, replace or leave it.
Tell us about the project.
A sentence or two is enough to start. A written quotation usually follows within one working day.
