Nyasha Hama

Backend & Platform Engineer
Go, TypeScript, Rust, PostgreSQL, Redis, Docker, CI/CD, observability, and production-minded product systems.

What I Build

I build public, working systems with backend depth and product discipline: Go APIs, TypeScript product surfaces, Rust infrastructure/database work, PostgreSQL schemas, Redis-backed workflows, authentication, observability, release gates, and Dockerized local environments.

My strongest current proof is in healthcare operations, property platforms, and upstream database/symbolic-execution work:

  • ClinicPulse: live clinic-operations platform for South Africa's public primary healthcare network.
  • StrataHQ: live sectional-title property operations platform for agents, trustees, and residents.
  • Upstream OSS: merged Rust database-engine work in Turso and Python/C tracer work in CrossHair.

Upstream Open Source

Project Merged work Proof
Turso Two Rust database-engine fixes around SQLite-compatible schema rewrites: preserving AUTOINCREMENT after DROP COLUMN, then clearing stale sqlite_sequence metadata when ALTER COLUMN removes an AUTOINCREMENT rowid alias. PR #6993 · PR #7117
CrossHair Python/C tracer change moving call target normalization into the C extension, with tests for bound methods, callable instances, reference behavior, and descriptor-error handling. PR #413
