What I do

Six things I get hired for — and two I get hired back for.

I own systems end-to-end: architecture, APIs, mobile clients, CI/CD and production support. The automation and conversational-AI work is where I move the needle fastest.

AI Automation & Agentic Workflows

I design n8n agents that take recurring operational work off people’s plates — orchestrating APIs, webhooks and LLM calls on a schedule or on demand.

  • Agentic workflow design with branching, retries and human-in-the-loop steps
  • API / webhook orchestration across third-party systems
  • Scheduled automation: reminders, task notes, notifications, reporting

Conversational AI & Chatbots

Production chat assistants that hold a real conversation, call real functions, and work in the languages your users actually speak.

  • Multilingual NLU (English, Kiswahili, Somali) at 95%+ intent accuracy
  • Structured JSON function-calling for search, booking, refunds, PNR generation
  • WhatsApp Business API deployment with automated status notifications

Full-Stack Engineering

End-to-end product work: data model, API, UI, deploy pipeline. I own features from architecture through production support.

  • Next.js 15 / React front-ends with typed, testable data layers
  • Python FastAPI & Django and Node.js services behind REST and GraphQL
  • PostgreSQL schema design and query optimisation

  • Microservices with Docker and Kubernetes
  • CI/CD with GitHub Actions; deploys on Vercel, AWS, Azure and GCP
  • Performance work for high-concurrency workloads (1,000+ live sessions)

Technical Leadership & Interviewing

Five months interviewing senior engineers for client organisations gave me a current, calibrated bar — and I hold my own work to it.

  • Scoping, sprint planning, and coordinating design / backend / mobile workstreams
  • Structured hire/no-hire recommendations on system design and coding ability
  • Code review culture and mentorship for junior developers

Experience

Three years of shipping — and one spent judging what good looks like.

From airport data pipelines to enterprise monorepos to leading an AI automation practice. Five months interviewing senior engineers in between, which recalibrated my own bar.

About

I build the thing that means nobody has to do it by hand again.

I’m a senior software engineer based in Nairobi, Kenya, working remotely with teams across time zones. The last three years have been spent on systems people actually use: enterprise Angular frontends inside Kyosk’s monorepo, data pipelines and anomaly detection for airport operations at JKIA, a trilingual booking assistant taking real bookings over WhatsApp, and now the mobile apps and automation layer at Intro Innovation Oy.

The thread through all of it is automation. I gravitate to the problems where a person is doing something repetitive that a system should be doing instead — and I want to own the whole path to fixing it, from the architecture down to the deploy that puts it live.

Between roles I spent five months as a contract technical interviewer, assessing senior engineering candidates on system design, coding ability and AI/automation skill for client organisations. Reading a few hundred engineers’ work up close changes the standard you hold your own to.

01

Own it end-to-end

Architecture, API, client, pipeline, production support. Handing off half a feature is how features die.

02

Automate the recurring

If a person does it every week and a system could do it every hour, that is the next thing I build.

03

Ship, then measure

TravellingGPT went from concept to deployed in three days. Real users beat a longer spec every time.
