We build AI-ready software that scales.
Design -> Innovate -> Transform
A global software engineering studio, established in 2018. We partner with startups, scale-ups and enterprises to design, build and ship production-grade software that is ready for the AI era, from fintech wallets to AI business platforms.
We are a team of passionate developers who use software to solve everyday problems. Qwerty Systems is an engineering studio, not a staffing agency or a reseller. A tight-knit team of senior engineers owns what we build end to end, from the first architecture decision to post-launch scale.
Every product we take on gets the same five commitments:
We're an engineering partner who stays until the system is stable, documented and yours.Cornelius Okaya, Founder & Lead Engineer
AI is changing how software is built and what customers expect from it. Our services are set up for that shift: we build products that use AI today, stay model-agnostic for tomorrow, and are architected to grow from hundreds of users to millions.
Production AI, not demos. Agents that complete real work, RAG over your own data, document intelligence and AI copilots inside your product, with evaluation and monitoring from day one.
React and Next.js frontends, Flutter apps for iOS and Android, and the APIs behind them, from design system to app store release.
Payment gateway orchestration, M-Pesa and mobile money, SACCO platforms and wallets handling millions of transactions across rails.
Product consulting, architecture and delivery for multi-tenant SaaS: microservices, event-driven systems and API gateways.
AWS and cloud-native infrastructure, containers, Terraform and CI/CD, plus monitoring with Prometheus, Grafana and Loki.
Sensor pipelines, monitoring dashboards, edge integrations and real-time telemetry, from hardware interface to cloud.
Get existing systems ready for AI: clean data foundations, open APIs that agents can use, and legacy code rebuilt or wrapped so it isn't left behind.
Replace manual back-office work with AI-assisted workflows, from invoice capture to customer replies, with people approving what matters.
Research, journeys and UI design for new products, plus codebase audits for founders who have outgrown their MVP.
AI is rewriting how software is built and used. Customers expect products that answer, act and adapt. Teams that build that way ship faster. Here is how we keep your product ahead of the change instead of behind it.
Customers ask instead of click. We add chat, voice and WhatsApp front doors on top of the same secure business logic.
Agents fill forms, reconcile payments and draft replies. We build them with clear limits, audit trails and a person in the loop.
We keep products model-agnostic, so you can move to a better or cheaper model without a rebuild.
We structure, clean and secure your data so AI answers are grounded in your business, not guesses.
Evaluations, guardrails, privacy controls and cost monitoring are built in from the first release.
We use AI-assisted engineering with senior review, so you get more working software per sprint without cutting quality.
Featured Project · AI business platform
One AI platform for the way a business works. Seven apps share one brain: a unified inbox for WhatsApp, Instagram, SMS and web chat with M-Pesa payments in chat, social scheduling, storefront and POS, multi-branch retail, accounting with eTims and iTax filing, and team AI grounded in company documents.
Client Project · Fintech wallet
Built for a client: KES and USDT wallets with M-Pesa built in. Deposit by STK push, withdraw to M-Pesa, buy, sell and swap USDT at a rate shown before you confirm, and run group wallets for chamas, family support and fundraisers with a shared, visible ledger.
Featured Project · School management SaaS
The school management system that runs the whole institution. Fees with M-Pesa and bank payments posted to the right learner, CBC, 8-4-4 and Cambridge academics, transport, payroll, stores and a parent portal that covers several children across schools, with KEMIS integration.
Featured Project · Waste management & recycling
Cleaner neighbourhoods, paid on time. Waste operators schedule pickups by estate, bill customers through M-Pesa or cash, and run field agents, while recyclers trade recovered materials on a built-in marketplace. Web dashboard plus an Android app on Google Play.
Featured Project · Care marketplace, Ghana
A platform that helps families in Ghana find vetted nannies, housekeepers, elderly carers, chefs and event staff. Profiles carry Ghana Card and background checks, reviews and rates, with in-app messaging, interview scheduling and booking paid by mobile money or bank transfer.
all live in production
Real-time crop analysis, sensor data visualisation and field reporting for commercial farms. Flutter app, NestJS BFF, Spring Boot backend and Terraform on AWS.
Food delivery with secure payments, real-time order tracking and restaurant management on web and mobile.
Mobile money, multi-currency wallets, group savings and payment orchestration.
Fees, CBC and 8-4-4 academics, transport, payroll and parent portals for whole institutions.
Omnichannel inboxes, POS, multi-branch stock and accounting for growing businesses.
Collection scheduling, billing, field agents and recycling marketplaces for circular cities.
Verified two-sided marketplaces with profiles, messaging, booking and mobile money.
Sensor pipelines, crop analysis and field reporting for commercial farms.
Our products run in Kenya and Ghana, and we know the integrations that make them work locally.
A focused sprint before any code
Design the system first
Working software every week
Yours to run and grow
A scoped project from discovery to launch, with a fixed plan you can hold us to.
A senior squad that joins your roadmap and ships alongside your own engineers.
Architecture and AI-readiness reviews, or technical due diligence, with a written report and a clear path forward.
