Let's build something great.
What I build
for you,
on purpose.
Seven years building products people actually use — web apps, mobile apps, APIs, and the full stack in between. I work with founders, teams, and companies who need someone who takes ownership, not just tickets.
Six service lines across development, design, and creative — pick one or combine.
Full-Stack Web Development
Complete web application development across the full stack — architecture, database design, API, frontend, auth, payments, and deployment. I take ownership of the whole thing, not just a layer.
- Next.js 16 App Router frontend (TypeScript + Tailwind v4)
- NestJS + Fastify API with Prisma + PostgreSQL
- Authentication — JWT, refresh tokens, Google/GitHub OAuth
- Role-based access control (RBAC)
- Stripe subscriptions + webhooks, or M-Pesa Daraja integration
- +5 more
Mobile App Development
React Native (Expo) apps built for real use — offline-first architecture, push notifications, deep links, payments, and app store submission. One codebase, both platforms, no compromise on quality.
- React Native (Expo) — iOS + Android from one codebase
- Expo Router for file-based navigation
- Offline-first data sync with queue management
- Push notifications — Firebase (FCM) + Expo
- Deep links and universal links
- +6 more
Backend & API Development
NestJS REST and GraphQL APIs, background job systems, webhook integrations, and data pipelines — built to scale, documented properly, and handed over in a state you can maintain.
- NestJS + Fastify REST API (or GraphQL)
- Prisma ORM + PostgreSQL schema design + migrations
- Background job system (Bull + Redis)
- Webhook handling with signature verification + retry queues
- Rate limiting, request validation, and input sanitisation
- +5 more
Code Audit & Review
A focused review of your existing codebase — security vulnerabilities, performance bottlenecks, structural debt, and a prioritised remediation roadmap. Written report, debrief call, actionable output.
- OWASP Top 10 security assessment
- SQL injection, XSS, CSRF, and auth vulnerability scan
- Dependency audit (outdated, deprecated, known CVEs)
- Database query performance analysis (N+1, missing indexes)
- Code structure and maintainability assessment
- +5 more
Graphic Design, 3D & Blender
Brand identities, marketing visuals, UI assets, 3D models, Blender renders, and product mockups — from concept to final file. Print-ready, screen-ready, or render-ready.
- Brand identity — logo, colour system, typography, usage guidelines
- Social media asset templates (Figma, all platform sizes)
- Pitch deck and presentation design
- Marketing banners and digital advertising assets
- UI asset creation — icons, illustrations, custom graphics
- +6 more
Video Editing
Professional video editing for product demos, social media content, YouTube, brand videos, and tech walkthroughs. Fast turnaround, clean cuts, subtitles, motion graphics, and colour grading included.
- Rough cut review before final delivery
- Colour correction and grading
- Audio cleanup, levelling, and background noise removal
- Subtitles / captions (SRT file + baked-in option)
- Motion graphics, lower-thirds, and title cards
- +5 more
Defined scope, fixed deliverables
Best for: new products, feature builds, redesigns. Clear scope, timeline, and price before we start. 50% upfront, 50% on delivery.
Ongoing capacity, monthly cadence
Best for: continuous development or keeping a senior engineer on call. Fixed hours per month. Rolling month-to-month or quarterly.
Time-boxed, single deliverable
Best for: code audits, one-off designs, or single video edits. Scoped upfront, paid in full at start, delivered by agreed date.
No ambiguity, no surprises. Every engagement runs the same five-step process — from the first call to the final handover.
Start with a discovery call →30 min to understand the problem, scope, and timeline. No obligation.
Detailed scope, deliverables, timeline, and pricing within 48 hours.
Contract signed, first payment, repo access, and we start.
Weekly progress updates, Loom walkthroughs, async-first communication.
