Open to founders, consulting & leadership roles

I build AI-powered products, automation systems & software businesses.

I’m Lakmal — an engineer who became a founder and AI automation architect. I turn hard engineering problems into products people rely on: browser automation, AI customer operations, and platforms built for outcomes.

Things I Built

A wall of products, not a list of repos.

Each of these started as a problem worth solving. Hover to peek at the architecture; click to go deep.

Engineering Deep Dives

The thinking behind the build.

Real case studies — problem, architecture, the hard decisions, and what I’d change today. This is how I reason about systems.

2024

Snappit

Browser automation is notoriously brittle. Selectors break on the smallest UI change, sessions drift and expire, and running real browsers at scale is…

Global Search Platform

Search was slow and inconsistent, bolted onto the primary database. Every query competed with transactional traffic, and results felt stale.…

QA Copilot

Manual QA is slow and inconsistent, and automated end-to-end tests are famously flaky — eroding trust until teams ignore failures and ship bugs anyway…

Engineering Toolbox

Not a skills list — a map of what I’ve built.

Every technology here earned its place by shipping something real. Explore the ecosystem to see how the pieces connect across products, platforms, and businesses.

TypeScript
Primary engineering language

The backbone of nearly everything I ship — frontend, backend, agents, and tooling.

Go
Performance-focused backend

High-throughput services, automation platforms, and systems where latency matters.

React & Next.js
Product & frontend

How I turn ideas into fast, polished products people actually want to use.

AI & Automation
Agents & workflows

LLM agents, browser automation, and workflows that delete real human drudgery.

Terraform
Infrastructure as Code

Reproducible infrastructure, ephemeral environments, and GitOps pipelines.

Google Cloud
Cloud architecture

Designing and operating scalable, cost-aware systems — twice GCP-certified.

Product Engineering

Turning ideas into fast, polished products across web and mobile.

TypeScript

My primary language across the entire stack — type-safe products, services, and agents.

Where it shows up

Outcome: Type safety end-to-end keeps fast-moving products refactorable and reliable.

These aren’t just tools I know — they’re tools I’ve shipped with. Let’s build something
How I Work

A small set of principles, applied relentlessly.

Not a manifesto — an operating system. These are the defaults I return to when the path isn’t obvious.

Build for outcomes

Not features.

A feature shipped is a cost until it changes a number that matters. I start from the outcome — cost saved, time returned, revenue unlocked — and work backwards to the smallest thing that moves it.

Writing

Notes on building things that last.

Engineering, product, AI, and the lessons that only show up after you ship.

What an Accounting Degree Taught Me About Building Software Companies

I trained as an accountant and became an engineer and founder. The detour wasn’t wasted — it’s my edge. On outcomes, distribution, and finding what’s true.

In Automation, Reliability Is the Product

Browser automation looks like a demo problem and is actually a reliability problem. What building Snappit taught me about why self-healing beats clever.

How I Cut a Cloud Bill by 90% Without Touching Latency

Cost is a feature. Here is the playbook I used to cut a workload’s cloud spend by ~90% while improving p99 — and why most teams leave this money on the table.
