Backend engineer with 8 years of experience, currently Engineering Team Lead at a fintech. I own the financial backend end-to-end: payment infrastructure across 7 rails (Stripe, M-Pesa, Basis Theory, direct bank APIs), serving hundreds of thousands of users in Kenya and Tanzania.
On the side I built https://watchdock.cc, an observability platform that processes 25M+ nginx logs and generates AI-powered incident fixes. Also shipped MyFinance AI, a personal finance tool with a custom ML model hitting 92.4% accuracy on spending predictions.
Open to senior backend, staff, fintech/payments, or founding engineer roles.

8 years building and shipping backend systems and full-stack products, mostly solo or in small remote teams. I like owning things end to end, from infra to the API to the parts of the frontend that touch it.
Most recent project: https://myfinance.cc, a personal finance SaaS that parses M-Pesa and bank PDF statements. Transaction categorization runs on a Random Forest classifier (TF-IDF + temporal features, ~95% accuracy on live data); spend forecasting uses a per-user RF regressor with 31 engineered features; anomaly detection via Z-scores.
Also built https://watchdock.cc, an observability platform (error tracking with SHA-256 dedup, uptime/SSL monitoring, container health, an AI-generated daily ops summary posted to Slack). I also maintain a few async-first PyPI packages (kenyan-counties, daraja-sdk).
More projects and code on my site. Happy to talk about any of it.

Hi, I'm a software engineer focused on backend systems and developer infrastructure.
I'm currently building Watchdock (https://watchdock.cc ), a lightweight monitoring and error tracking platform designed to reduce noise and improve signal clarity for SaaS applications.
What I’ve done with Watchdock:
- Designed and implemented an error ingestion API
- Built event grouping & processing logic
- Developed a Python SDK for error capture
- Designed alerting workflows
- Deployed and managed production infrastructure
I enjoy working on backend systems, reliability, observability and tools that improve developer experience.
I’m looking for roles in backend engineering, platform engineering or infrastructure-focused teams where I can contribute to production systems.
