I design and ship production-grade products end-to-end — AI/RAG platforms, mobile healthtech, and trading/fintech systems — from first commit to live deployment.

Featured Work

Things I've shipped

Production-grade products across AI, healthtech, civic tech, and fintech — from database schema to live deployment.

Civic Tech / AI

Macho ya Mwananchi

LIVESolo build

A civic-accountability platform exposing ghost projects and misused public funds in Nandi County, Kenya — built on official government audit data.

The Problem

Government audit reports are public but locked in 400-page PDFs ordinary citizens can't read.

Data source

  • AI Audit Translator — ask questions in Swahili or English via a RAG pipeline (ChromaDB + Google Gemini 2.5 Flash) with a direct-Gemini fallback
  • GPS citizen verification: photo + live coordinates feed a consensus engine that updates a project's status
  • Anonymous corruption reporting with tracking codes
  • Interactive Leaflet evidence map with real government data overlays

Healthtech · Full-Stack + Mobile

Helix

Case StudySolo build

A genetic-compatibility dating platform: users store an encrypted genotype/blood profile (typed or OCR-scanned from a medical report), then match with a sickle-cell / rhesus "traffic-light" verdict that gates whether matched profile photos un-blur.

The Problem

Couples need accessible sickle-cell & blood-compatibility guidance before starting a family — without exposing deeply sensitive genetic data.

Data models

  • FastAPI + PostgreSQL backend (SQLAlchemy 2.0, 13 Alembic migrations) with a 15-pair genotype engine that explains per-child inheritance risk (e.g. 1-in-4) as a GREEN/AMBER/RED verdict — framed as educational, not diagnostic
  • Field-level Fernet (AES) encryption of genotype/blood data via a custom SQLAlchemy type; JWT + bcrypt + server-verified Google OAuth; per-route rate limiting and an immutable audit log
  • Privacy-by-design: genetic markers pseudonymised behind a random subject-ref decoupled from user identity; GDPR / Kenya-DPA consent gates, an 18+ gate, and a right-to-erasure cascade
  • Flutter app (Provider + go_router auth guards, silent re-auth, FCM push, 16 screens), Tesseract OCR to read a report photo, and server-enforced photo-blur via signed Cloudinary URLs so blur can't be bypassed

AI Trading Bot

Open SourceSolo build

A self-hosted algorithmic-trading research harness — a 9-gate signal + risk pipeline (Kalman, HMM regime detection, Bayesian sizing, half-Kelly) over TimescaleDB time-series, with an MT5 demo bridge and Telegram alerts. Paper-trading by default.

The Problem

Learning quant systems design means building the full loop — market data, strategy, multi-stage risk gating, execution, and monitoring — not just a single indicator.

Backend

  • FastAPI + TimescaleDB hypertables + Redis + ChromaDB across 4 Docker services; live market data via Yahoo Finance
  • 9-gate signal & risk pipeline: news blackout, drawdown circuit-breaker, Kalman trend, multi-timeframe confluence, VWAP order-flow, HMM regime, conviction sizing
  • 7 quant-math modules — Kalman filter, 3-state HMM, Bayesian win-probability, half-Kelly sizing with a 5% cap and negative-expectancy rejection
  • Paper-trading journal by default; optional MT5 demo order routing (MQL5 EA) and Telegram signal broadcasting

Intelliverse — AI Agent Builder

LIVEInternship · Team Lead

A deployed multi-user platform where anyone can build custom AI chat agents — each with its own persona and uploaded document knowledge (RAG) — then share or fork them.

The Problem

Non-technical users want AI assistants grounded in their own documents, without writing code or handling an API key themselves.

Fly.io

Deployed on

  • Flask (app-factory, 4 blueprints) backend with server-rendered Jinja + vanilla-JS frontend; PostgreSQL via SQLAlchemy + Alembic; Dockerised and deployed on Fly.io with a /health readiness check
  • Document-RAG: users upload PDF/DOCX/TXT → 500-char chunking → Google Gemini embeddings → Pinecone vector retrieval (top-k) grounding each agent's answers
  • Hardened auth & safety: Google OAuth + password login with account lockout, CSRF protection, Talisman CSP/HTTPS, per-route rate limiting, and an immutable audit log
  • Resilient LLM calls via a model-fallback chain (Gemini 2.0-flash → 1.5-flash → 1.5-pro); agents and chats can be shared and forked between users

Built during an internship as the lead engineer, working alongside 1–2 other contributors.

PSP Platform — PayCore

Case StudyTeam · Core contributor

A multi-country payment orchestration platform routing mobile money and card payments through one provider-agnostic core.

The Problem

Businesses operating across Africa need a single integration that handles MTN MoMo, M-Pesa, and card payments without per-provider re-engineering.

  • Gevverson's contribution: payment-rail adapters and hosted checkout flows, plus tests, inside the provider-agnostic core
  • Signature-verified provider webhooks and idempotent transaction handling
  • Hosted tokenized checkout so card data never touches the server (PCI-aligned design)
  • Live sandbox demos across MTN MoMo, M-Pesa, and cards in a pnpm monorepo with Vitest suite

Team project owned by a collaborator. Gevverson built payment-rail adapters and the hosted checkout flows as a core contributor.

About

Engineer who ships

I'm an engineer who ships complete, production-grade products from research to deployment — solo across AI, healthtech, civic tech, and fintech, and as a core contributor on a team-built payment platform.

Comfortable across the full stack: TypeScript/NestJS and Python/FastAPI on the backend, React/Next.js and Flutter on the frontend, and LLM/RAG systems with Pinecone and ChromaDB vector search and Google Gemini at the AI layer. I care about the details that matter — security, performance, and real-world correctness.

Based in Nairobi, Kenya. Open to remote work worldwide. Whether it's a 0-to-1 product, a complex integration, or an AI feature you need to get right the first time — I'm built for that kind of challenge.
