Services

What we build

Six capabilities covering the full stack, so no part of your product falls between vendors.

All services

Web application development

Dashboards, portals, marketplaces and internal tools, built to stay fast under real traffic.

Mobile app development

Android and iOS apps plus installable web apps, sharing a codebase with your web product where that saves cost.

AI and automation

Agents and pipelines that carry real workload: content generation, analysis, orchestration and retrieval over your own data.

E-commerce and payments

Storefronts, checkout and the admin behind them, integrated with M-Pesa, cards and escrow.

Security engineering

Authorised penetration testing, architecture review and hardening, with findings your developers can act on.

Cloud, DevOps and support

Deployment pipelines, monitoring, backups and the ongoing maintenance that keeps a live product healthy.

Work

Selected projects

Products we have designed, built and taken to production, including the payments and operations behind them.

Process

How we work

Five stages, with working software in your hands at the end of each one.

01

Discover

We learn the business, the users and the constraints, then agree what success means in measurable terms.

02

Design

Architecture, data model and interface designed together, so the build carries no hidden surprises.

03

Build

Short cycles with software you can open and use, rather than status reports about work you cannot see.

04

Ship

Deployment, monitoring, live payments, and a handover with documentation and account access that is yours.

05

Support

Fixes, iteration and new features on an ongoing basis, because a live product is never finished.

Our approach

How we build

Complete delivery

We build the whole product, including the admin tools, payment flows and infrastructure that make it usable in a real business. Not a demo that needs finishing later.

Correctness where it counts

Escrow that holds funds until delivery. Risk limits enforced in the execution path. Settlement that reconciles and can be audited. The safeguards live in the code.

Practical use of AI

We apply AI where it measurably improves the product, such as content pipelines and tool orchestration, and use conventional engineering everywhere else.

Industries

Sectors we have worked in

We have built and run production systems in each of these, so the domain knowledge is not guesswork.

Retail and e-commerce

Catalogues, carts, checkout and the inventory admin behind them.

Fintech and payments

M-Pesa and card integrations, escrow settlement, reconciliation and enforced risk controls.

Cyber security

Authorised offensive testing, tooling automation and secure architecture.

Social platforms

Profiles, matching, moderation, real-time chat, video calling and live streaming at scale.

Marketing and growth

Autonomous content pipelines, SEO engines and AI visibility measurement.

Logistics and marketplaces

Multi-sided platforms coordinating buyers, sellers and riders through delivery and release.
