Hello World

Software engineer + product builder

Faith Catherine Otieno

Software Engineer + Product Builder

Full-stack engineer turning ambitious ideas into real products across frontend, backend, and user experience.

Building with product sense

FO

Full-stack systems, mobile UX, and product loops.

Pursuit

Hyperlocal discovery for Nairobi.

Current focus

Mobile-first products

Walking on EarthPursuit HQAndela network

Experience snapshot

The range to shape, build, and ship.

I work best where product judgment and engineering execution meet: clarifying the value, designing the system, building the experience, and iterating with real constraints in mind.

3+

years experience

Production work across digital health, content strategy, client delivery, and independent product building.

10+

shipped projects

Mobile flows, GraphQL features, analytics instrumentation, dashboards, and end-to-end product experiments.

E2E

ownership

Comfortable moving from product question to schema, API, UI, deployment, QA, and iteration.

Mobile -> Backend

product engineering

React Native interfaces, Apollo/GraphQL integrations, Django services, PostgreSQL data models, and delivery workflows.

Featured work

Product stories with engineering underneath.

Each piece is framed by the product problem, what I built, and the impact or capability it represents.

Flagship product

Pursuit

Founder, sole engineer, and product owner

Problem

Nairobi event discovery is useful but fragmented. Good recommendations live across social feeds, posters, WhatsApp groups, and memory, which makes planning feel harder than it should.

What I built

I am building a mobile-first discovery product with React Native, Django, GraphQL, PostgreSQL, Redis caching, location-aware filtering, event deduplication, authentication, onboarding, and Render-hosted environments.

Impact

Pursuit is my clearest 0-to-1 product: I own the product decisions, schema, API, mobile UI, infrastructure, and case-study thinking behind the build.

Mobile + web product engineering

Walking on Earth

Full-stack software engineer on a UK digital health platform

Problem

A consumer wellness product needs calm user flows, reliable API-driven features, clear analytics, and stable release practices across both web and mobile surfaces.

What I built

I shipped GraphQL-integrated React and React Native features, worked with Apollo Client query/mutation/fragment patterns, contributed to reusable TypeScript component libraries, and collaborated on evolving schema contracts with backend engineers.

Impact

I helped improve delivery quality through Firebase/Mixpanel instrumentation, Sentry monitoring, WCAG accessibility improvements, legacy refactors, and async-first collaboration across UK and EAT timezones.

Data + recommendation systems

Reaction Power

Developer and data analyst

Problem

The team needed clearer content direction from audience signals: what topics were gaining traction, how users engaged, and what recommendations could guide digital strategy.

What I built

I built a Python-based content recommendation system using social listening signals and engagement trends, implemented GA4/GTM tracking, managed WordPress content, and produced Looker Studio reports.

Impact

The work translated scattered performance data into executive-facing insights and practical recommendations for content, SEO, and digital engagement decisions.

About me

Engineer. Builder. Product thinker.

I am a software engineer who works across the full path from product question to shipped experience. I care about clear architecture, thoughtful interfaces, and the practical delivery decisions that make software usable.

I like products where the backend decisions, UI details, and business logic all have to make sense together.

That is why Pursuit matters to me: it is not just a codebase, it is an attempt to make local discovery feel cared for. The same thread runs through my client and team work: make the useful thing feel intentional.

How I work

I care about product clarity before implementation speed.

I like systems that are simple enough to maintain and strong enough to scale.

I learn quickly, document the messy parts, and keep the user in view.

Career timeline

The path has been practical, product-facing, and increasingly self-directed.
