Most teams juggle a payroll tool, an HR tool, a tax consultant, and a spreadsheet that nobody trusts. HalaOS collapses those into a single system with local compliance built in — from Malaysia's EPF and SOCSO to US state-by-state filings.

Every line of the core is open source, so teams can audit, self-host, or extend it. The managed product removes the ops burden entirely.

Payroll

Multi-country runs, statutory contributions, payslips in local languages.

Tax

Automated withholding, year-end forms, jurisdiction-aware filings.

HR

Employee records, onboarding, time-off, and self-service portals.

Open source

Permissive license. Self-host the core or use the managed cloud.

Practical tools.
Durable software.

01

Product engineering

Full-stack builds for web and mobile. TypeScript, Next.js, Postgres, and the unsexy infrastructure choices that mean you can sleep at night.

TypeScript · Next.js · PostgreSQL · Rust · Supabase
02

Platform & infrastructure

Multi-tenant platforms, API design, compliance-aware architectures. Systems that stay correct as you add jurisdictions, currencies, and edge cases.

AWS · Cloudflare · Kubernetes · Event-sourced systems
03

Design & UX

Interface design for tools people use every workday. Not marketing pages that win awards — software that disappears into the task.

Figma · Design systems · Motion · Accessibility
04

Technical advisory

For founders who need a straight answer before they write the cheque. Architecture reviews, hiring plans, build-versus-buy calls.

Retained · Project-based · Due diligence

Small team. Short loops. Shipped software.

I

Listen first

We start with the actual problem — not the feature list. A two-week discovery turns a vague brief into a precise scope.

II

Ship weekly

Something working lands in front of you every Friday. We'd rather show you imperfect software than a perfect Figma.

III

Hand over cleanly

Documentation, tests, and a runbook your team will actually use. No mystery code, no "only I know how it works."
