About
I'm Lucy Wanjiku Mwaura — five years shipping production platforms across agriculture, HR, and B2B SaaS: multi-tenant models, background jobs, dashboards, and APIs that hold when traffic gets weird.
Based in Nairobi. Comfortable owning a slice of the stack from MySQL / Postgres to React, and the ops glue in between.
From schema to shipping UI — I own the path end to end.
Caches, queues, indexes, retries. The boring parts that keep prod calm.
Small increments, real telemetry, tight feedback — not six-month rewrites.
NLP and ML only where they cut real operator time — not as decoration.
Selected work
End-to-end herd, health & inventory platform
Farmers were juggling spreadsheets, paper records, and ear-tag readers — losing hours per week and, worse, losing sight of sick animals until symptoms escalated.
Onboarding, leave, payroll & performance in one suite
Growing companies were paying for four disconnected HR tools that didn't talk to each other.
NLP-powered assistant for farmers
Farmers in the field need answers in the language they think in — plain, spoken, quick.

From collaborators
“We handed Lucy a mess of leave balances and four tools that didn't talk. She put the HRMS live before our next payroll run — managers actually use it.”
“The livestock dashboard is what our field team opens first. Alerts fire when weight drops — we stopped losing animals to late detection.”
“Clean tenancy boundaries, GraphQL that didn't leak across shops, and a deploy we could roll without waking anyone. That's rare.”
Writing
Row-level vs schema vs database-per-tenant — what I pick after shipping four SaaS platforms.
Intent classifier + curated corpus beat a vague LLM for disease and feeding questions.
Backups, alerts, secrets, and the runbook that saved a Sunday — still my default.
