Sri Lanka · Where it started
My first lines of code
I grew up here, and this is where I started to code. Nothing came ready-made. You figured it out yourself.
Build my hero. I review before it ships.
Software engineer @ in2event · I direct AI agents · Netherlands
Agents write the code. I plan it, review it and ship it.
I'm Janitha. For five years I built React and TypeScript products by hand. Now I brief AI agents, split the work between them, read every diff, and catch the bugs before they reach production.
This build: 24 agents · 42 tasks · 1 bug, caught in my reviewThis build: 25 tasks · 1 bug caught by me
How I work now
I don't type most of the code anymore. I'm still responsible for all of it.
Every AI session starts from zero. Until it has been handed its working context, it doesn't know the codebase, the history, or what we decided yesterday. I think of it like helping a newborn stand up and walk: I give it context, a direction and guardrails, and I stay close for the first steps.
- 1
Brief
I write down what we're building, the constraints, what "done" means and what must not change.
- I decide
- Goal, constraints, definition of done
- Agents do
- Read the codebase, ask what's unclear
- 2
Plan
I break the work into pieces small enough to review, and ask what could go wrong before anything is written.
- I decide
- Scope, order, which risks matter
- Agents do
- Explore the code, draft plans, list failure cases
- 3
Orchestrate
I run several agents side by side, each with one task and clear boundaries, so their changes don't collide.
- I decide
- Who does what, when to stop or redirect
- Agents do
- Write code and tests in parallel
- 4
Review
I read every diff. Years of writing React and TypeScript by hand is how I notice the bug that still passes the tests.
- I decide
- What gets sent back, what is good enough
- Agents do
- First-pass review, run tests, apply fixes
- 5
Ship
I run the release: checks, preview, deploy, and watching it afterwards. If it breaks, it's mine to fix.
- I decide
- Release or hold, rollback
- Agents do
- Changelog, release notes, routine checks
AI didn't teach me how to build. It changed how fast I can build.
Work · with a team
The operations behind a festival
I work across multiple products at in2event, an event management platform that powers the operations behind major festivals and venues: artist management, backstage logistics, staff scheduling, accreditation, access control and real-time event operations. Among them is Valve Vacation, a website and app the team built from scratch. It is a complex ecosystem. Here is one day of it.

Every pass says who may go where. Scanners at each zone check it.
The check has to be instant at the door, and still right when the list changed a minute ago.
The day and its numbers are made up, to show how the products fit together. The products are real, and I work across them.
Work · on my own
From a business idea to a working product
FitWithLexy is my wife's personal training business. I built its website from scratch, by myself: online payments, session management, a separate admin panel, and AI-generated promotional videos built into the pages. Everything from the site her clients see to the tools she needs to manage the business behind the scenes.

Foundation
I Know What's Behind the Prompt.
Before AI became part of my workflow, I was already building products from scratch. Years of hands-on engineering taught me what works, what breaks, and why. Today, that foundation helps me guide AI with intention and challenge its output.
The prompt
- 01It is not one form. It runs in phases.
- 02People register their guests as well as themselves.
- 03Flights, hotels, activities and payment all hang off it.
What it leaves out
Toolbox
What I build with prompts today, I used to build by hand.
That is why I know what I'm doing. Every tool here is one I worked in by hand, on the products above. AI has made that work faster. Knowing the tools is what lets me give it better instructions, recognise when something isn't right, and guide it toward a better solution.
Pick a stage to see what it leans on, or point at a tool to see where it is used.
One piece of work, start to finish
Every tool here is one I have worked in by hand.
Build
AI writes much of the code, in the tools I wrote in by hand for years.
That is why I can follow every line that comes back, and say what to change.

How I got here
Sri Lanka, North Macedonia, the Netherlands. Three places, and what each one left me with.

A new country and a new team
Working somewhere unfamiliar, with a team I didn't know, is where I grew most as an engineer.

Whole products, built by hand
Software engineer at in2event, across multiple products behind major festivals and venues. With the team, I worked through every part of them: the architecture, the code, the design decisions.
04/Nowwith AI in the work
I was building complete products from scratch long before AI became part of the development workflow.
Back then everything took a lot more manual engineering, problem-solving and figuring things out yourself. Now imagine what someone with that foundation can build with the tools we have today. The possibilities have become a lot more interesting.
