Felix Kebaya AI Engineer, LLM Trainer, AI Strategist Start a project

About

One person, the whole technical job.

I build AI into real software, then write down exactly how.

I am Felix Kebaya — an independent AI engineer and developer working from Nairobi with clients across Kenya, Liberia, Australia and the United States. I build the software, design the collateral around it, and write publicly about how it was done so you can judge the work before hiring me.

Most of my clients are small teams and owner-run businesses. They do not need an agency and they do not want a project manager sitting between them and the person writing the code. They want someone who answers, scopes honestly, and ships every week.

The range is deliberate. A business that needs a booking system usually also needs the brand collateral, the automation behind the admin, and someone to keep it all running afterwards. Hiring three suppliers for that costs more and takes longer than hiring one person who understands all of it.

Everything I do

The full range, honestly described.

Not a list of everything I could theoretically attempt — these are the things clients have paid for and been happy with.

AI automation and pipelines

The work that removes a recurring manual task: documents in, structured answers out, running on a schedule without anyone watching it.

  • Agents and tool use
  • RAG over your data
  • Document pipelines
  • Scheduled runs
  • Evaluation
  • Cost control

LLM engineering

Getting a model to behave reliably on your data — the prompting, retrieval, tuning and evaluation that separate a demo from something you can ship.

  • Prompt systems
  • Fine-tuning
  • Embeddings and vector search
  • Context engineering
  • Eval harnesses
  • Guardrails

AI strategy and training

Where AI genuinely pays for itself in your business, and bringing your team up to speed on using it without creating new problems.

  • Opportunity audits
  • Build-or-buy calls
  • Team workshops
  • Model selection
  • Policy and guardrails
  • Vendor selection

AI features in real products

Assistants, search, classification and extraction built into software people already use, rather than bolted on as a separate toy.

  • In-app assistants
  • Semantic search
  • Classification
  • Extraction
  • Streaming interfaces
  • Usage analytics

Custom web applications

When the off-the-shelf tool has run out of room: portals, ordering systems, dashboards and internal tools.

  • ASP.NET MVC
  • PHP
  • REST APIs
  • Databases
  • Role-based portals
  • Reporting

WordPress development

Custom themes and plugins written for how a business actually runs, plus the care work that keeps them running afterwards.

  • Custom themes
  • Custom plugins
  • WooCommerce
  • Migrations
  • Speed and Core Web Vitals
  • Care plans

Design and video

Company profiles, brand collateral and edited video — the material a business needs alongside the software, from the same person.

  • Company profiles
  • Brand identity
  • Pitch decks
  • Promos and explainers
  • Social cutdowns
  • Motion graphics

Technical writing and content

Hands-on writing for an audience of engineers, and content systems for sites that live or die by organic search.

  • Tool reviews
  • Build walkthroughs
  • Documentation
  • Sponsored coverage
  • Technical SEO
  • Content systems

Working with me

What you can count on.

An honest no

If your problem is not one I can solve well, I say so in the first reply and point you somewhere better. It costs me a project and saves you a quarter.

A fixed scope

Everything is written down before anything is built: what gets made, what it costs, when it lands, and what is explicitly out of scope.

Weekly on staging

Something you can click through every week, not a status report. You see the thing taking shape and can change direction early.

No lock-in

You own the code, the documentation and the accounts. If you want to take it to another developer, everything they need is already in your hands.

Tell me what you are building.

Describe the problem in a few sentences: where it is stuck, what you have already tried, and roughly what it is worth solving.
