Khamisi Lawrence, Senior Software Engineer. Multi-tenant web platforms: secure, fast, tested.

Hi, I'm Khamisi

I'm a Senior Software Engineer and Lead Product Engineer at GENR8-3D. I design and ship multi-tenant web platforms that are secure by default, fast on first load, and covered by tests.

What I'm building now

School Management System: a multi-tenant web platform for schools, now in a live pilot. I'm the sole engineering owner. I took it from a mock-data prototype to a school that no longer uses paper registers and grade spreadsheets.

  • Per-institution data isolation across 7 user roles, enforced by about 2,650 lines of Firestore security rules with automated rule tests
  • 88% smaller entry bundle (3.88 MB to 0.46 MB) through lazy-loaded routes and query caching
  • Test suite grown from 3 to 345 files (Vitest, Playwright) in about 10 weeks
  • 69 merged PRs built with a spec-first, AI-agent workflow (Claude Code), with automated guard tests and my own review

The source is private (owned by GENR8-3D). You can try the public demo: sms-demo.solutions.genr83d.com

Selected work

Project What it shows
School Management System demo · Case study A backend-free demo built in 7 days: 4 roles, 30+ pages, 34 Playwright specs with accessibility checks
GENR8 Pipeline demo · Case study A deterministic data engine generating a year of operations for 7 businesses, verified by invariant tests
Geo-Info REST API Go (Echo) API with in-memory caching, per-client rate limiting and Swagger docs

How I work

  • Spec first. I write down the problem, the data model and the security rules before building a major feature.
  • AI agents, human ownership. I direct AI coding agents (Claude Code, GitHub Copilot) and own the architecture and review. Automated guard tests catch what review misses.
  • Releases you can trust. Semantic versioning, a changelog, and GitHub Actions checks on every pull request and release.
