Applications.
Application development for Kenyan fintechs, logistics teams, and SaaS founders. Web apps in Next.js, mobile in React Native or Flutter, back-ends in Node or Django, M-Pesa plumbing that actually works in production.
We ship custom applications for Kenyan fintechs, logistics operators, edtech platforms and SaaS founders targeting East Africa. Our strike zone is the MVP-to-Series-A window — where every sprint has to earn its keep and technical debt compounds faster than revenue.
Mobile is React Native (shared codebase for iOS + Android + web), native Swift/Kotlin when performance demands it, Flutter when the team already knows it. Back-ends in Node (NestJS, Fastify), Python (Django, FastAPI) or Go. Databases on Postgres, Redis for cache, S3-compatible object storage.
What teams hire us to fix.
- 01An MVP that can't survive real usersYou shipped fast, now 200 users have broken the prototype. We refactor the hot paths, add observability, and put you on a stable base without a six-month rewrite.
- 02A payments stack that fails one in twenty timesDaraja has callbacks that never arrive, STK push expiries, and idempotency gaps. We have shipped it before, we know the retry patterns, and we write tests that catch them.
- 03A React Native app with a 400 MB buildYour app bundle won't download on a 4G-capped user. We audit dependencies, move to Hermes, ship code-splitting, and bring the install under 30 MB.
- 04Internal tools built on 17 Google SheetsYour ops team is the real product. We replace the sheets with a proper web admin — auth, audit trail, role-based access — in four to six weeks.
Everything you walk away with.
Product strategyJobs-to-be-done, user research, competitive scan, roadmap with sized milestones.
Design systemTokens + components in Figma and code. Extensible, documented, themed.
Mobile appReact Native (TS), Expo or bare, Hermes, native modules where needed.
Web appNext.js + React Server Components, Tailwind, Auth.js or Clerk, Postgres.
Back-end & APIsREST or GraphQL, OpenAPI documented, rate-limited, versioned.
IntegrationsM-Pesa Daraja, SMS (Africa's Talking, Twilio), email, KRA e-TIMS, firebase push.
ObservabilitySentry for errors, PostHog or Amplitude for product, Datadog or Grafana for infra.
CI/CDGitHub Actions, preview envs per PR, EAS Build for mobile, Terraform for infra.
A calm, five-step engagement.
- 01Product strategyUser interviews, JTBD map, feature shortlist, roadmap, and a sized MVP.
- 02Design systemTokens, components, and a figma/storybook library the dev team can extend.
- 03Interface designScreens, flows, and micro-interactions. Prototyped in Figma, tested with real users.
- 04BuildSprints of two weeks. Staging, preview envs per PR, weekly demos, monthly roadmap review.
- 05Launch & iterateObservability, analytics, and a month-one iteration plan. Metrics are on the wall.

Questions we get often.
React Native or Flutter?
Default is React Native because the web team can contribute code and UI libraries are mature. Flutter is a good answer when the team is already Flutter, or the UI needs are very custom on mid-range Android.
Will you work with our in-house engineers?
Yes. Many of our engagements are embedded — we slot one or two engineers and a designer into your sprints, work in your repo, and follow your code-review culture.
Do you handle Play Store and App Store submissions?
We do. EAS Build, fastlane for uploads, review metadata, privacy nutrition labels, data-safety forms — we ship the listing, you own the developer accounts.
Is the code ours?
From day one. Everything is in your GitHub organisation. We assign copyright in the contract and hand over admin of every third-party service.
Can you plug into M-Pesa, KCB Buni, or Equity Jenga?
Yes — we have shipped M-Pesa Daraja (STK, C2B, B2C), KCB Buni and Equity Jenga Pay integrations, and we understand the idempotency and callback retry patterns that all three need.
What if we only need design?
That is a common engagement: we do a 4–8 week product design sprint, hand you design files + a component library, and go. Your in-house engineers build.
