Web systems
Web applications, booking platforms, dashboards and internal tools built for day-to-day operations.
StackMoth, independent software studio
Software, automation & connected systems.
StackMoth is the studio of Lahiru Hettiarachchi. I build dependable digital systems for real business operations: web platforms, automated workflows, cloud infrastructure and connected hardware.
01 / Capabilities
What I build
Automation & integrations
Workflow automation and integrations that connect the tools a business already runs on, removing repetitive manual work.
Connected & IoT systems
Device, sensor and lighting networks: designed, installed and maintained for years of continuous operation.
Infrastructure & deployment
Linux servers, Docker, CI/CD pipelines, monitoring and backups across AWS, GCP and DigitalOcean.
02 / Selected work
Systems in production
Court reservation & payment platform
Multi-tenant booking and payments across two live basketball facilities. A double booking is refused three times over, in the database as well as in the application.
CourtRes lighting automation
Raspberry Pi, Zigbee and MQTT floodlight control, running unattended at two venues since 2024. A light counts as off only once the light itself says so.
Invitrack receivables
Invoicing and receivables with financial integrity enforced in PostgreSQL rather than the application, and a CI pipeline that proves it on every pull request.
SILK hoardings and banners
Site hoardings and exhibition banners for a Rajagiriya development, authored entirely in HTML and CSS and exported at print resolution by a headless browser.
Six case studies in full, with the live systems linked, at stackmoth.com/work. Client names appear with permission. Code is on GitHub.
03 / Working style
How I work
Direct communication
You talk to the engineer building your system. Nothing is lost between sales, project managers and developers.
End-to-end ownership
One accountable owner from the first conversation through deployment and long-term maintenance.
Production-minded engineering
Systems are built to be operated: logging, backups, monitoring and documentation come standard.
AI-assisted, human-accountable
AI tools speed up delivery. Every change is reviewed, tested and owned by me.
04 / Contact
Have a system that needs building?
Tell me about the operation you want to support or the manual work you want to remove. I reply personally, usually within a day or two.
