    Stock-market widgets for a major US bank

    Screeners, data tables and interactive charts that financial advisors, traders and their clients use every day.

    How do advisors, traders and their clients get fast, reliable market data inside the bank's own platform?

    Built: screeners, data tables and interactive charts across Vue, React and ASP.NET, backed by ASP.NET Web API and Node.js services, with Jest and NUnit tests and a streamlined CI/CD pipeline.

    Result: running on a platform that handles about 3.5 million requests a day, released every six weeks in step with the bank.

    AST: patent-data platform

    A patent-data application needed a modern interface and better search performance.

    Built: new Angular modules with AG Grid and Ant Design, NestJS REST APIs over Hasura, GraphQL over PostgreSQL for patent data, Firebase sign-in, and Docker services on GCP Cloud Run with Cloud SQL.

    Result: a modernized app with tuned Elasticsearch search, shipped through CI/CD.

    Which of the 516 stocks in the S&P 500 and NASDAQ 100 are worth a swing trade of 2 to 10 days?

What I build

Three kinds of work, one standard: clear scope, clean code, no surprises.

  • Web apps

    Customer portals, booking systems, dashboards and the internal tool your team keeps asking for. Fast, accessible and easy to hand over.

    You get

    • a written scope before any code
    • sign-in, payments and admin where you need them
    • hosting, monitoring and handover docs

    Typically 4–10 weeks

  • Mobile apps

    iPhone and Android from one codebase, with the admin side to match, taken all the way through the app stores.

    You get

    • an app that feels native on both
    • push notifications and offline mode
    • App Store and Google Play submission

    Typically 6–12 weeks

  • AI & automation

    Let software do the dull parts: document processing, smart inboxes, assistants that know your own data. I'll also tell you when AI is the wrong tool.

    You get

    • an honest audit of what's worth automating
    • guardrails, costs and privacy agreed up front
    • connected to the tools you already use

    Typically 1–4 weeks

Also: rescues and upgrades of existing apps, and plain-language advice for non-technical founders.

How working together goes

No mystery, no surprise invoices.

  1. Email me

    A few lines is plenty.

  2. Free 30-minute call

    The problem, the must-haves, a budget range.

  3. Fixed proposal

    Scope, timeline and price in writing. Changes get a quote first.

  4. Weekly demos

    Click through real progress on a live link, not a status report.

  5. Launch and handover

    Your code, your accounts, documented, with 30 days of fixes on me.

Who you'll work with

I'm Harith Kotelawala, a full-stack developer in London, Ontario, Canada.

Picked for your project, not for my résumé.

Frequently asked questions

Do you work with non-technical founders?

Most of my clients are. I explain trade-offs in plain language and keep the jargon on my side of the desk.

What does a project cost?

It depends on the scope. You get a fixed price after our call, before any work starts.

How long does it take?

A focused web app or automation: 2–6 weeks. A mobile app: 6–12 weeks.

Who owns the code?

You do, from day one: your repository, your accounts, your data.

Can you take over an existing app?

Yes. I start with a short paid audit so we both know what we're dealing with.

What happens after launch?

30 days of fixes are included. After that, a small monthly care plan or pay-as-you-go.

Where are you based?

In London, Ontario, Canada. I work remotely with clients across Canada and the US, on Eastern Time.

Got a project in mind?

Send three lines: what it is, who it's for, and when you need it.
