Systems ThatHold Their Ground.
Yahventech designs, builds, and maintains complete technical systems for businesses across East Africa — web platforms, mobile apps, IoT networks, and applied AI. One partner, full stack.
Six disciplines. One team.
Web & Platform Engineering
Product platforms, dashboards, and internal systems built to scale. From MVP to enterprise architecture.
Mobile Applications
iOS and Android apps — native performance, cross-platform reach. Designed for real users in real conditions.
Connected Hardware / IoT
Sensor nodes, gateways, and cloud telemetry. Bridging physical environments to intelligent dashboards.
Networking & CCTV
Site surveys, structured cabling, switching, and IP camera systems. Reliable infrastructure from the ground up.
Applied AI Systems
Computer vision, forecasting, and personalization engines — deployed in production, not just prototyped.
Support & Maintenance
Monitoring, incident response, and iteration after launch. Systems that stay healthy long-term.
Systems we've shipped.
Rentopia
A rental marketplace connecting tenants and landlords in Nairobi. Verified listings, in-app messaging, and mobile money plus card payments — built to work in the Kenyan market.
FortuneMotors
An inventory and sales CRM replacing spreadsheets across multiple vehicle-dealer branches. Lead pipelines, margin reporting, and branch-level analytics — replacing chaos with clarity.
HMS
A building-monitoring IoT system using Arduino-based sensor nodes streaming temperature, humidity, and occupancy data to a cloud dashboard with threshold alerts.
Chama
A chama (savings group) management platform automating member contributions, loan disbursement, meeting records, and dividend calculations — with M-Pesa integration for collections and payouts.
AI Insight Trading
A trading platform with AI-driven market insights and signals — forecasting and anomaly detection that help traders make data-backed decisions in real time.
API Gate
A centralized API gateway handling routing, authentication, rate limiting, and observability for a microservices backend — one entry point, full control.
Mobile Homecare
A mobile app for booking and managing home-based care services — caregiver matching, scheduling, and secure payments for families and providers.
Engineered for reliability.
We don't just write code — we architect systems that businesses depend on daily. From Nairobi to Kampala, our stack runs in production.
Full-Stack Depth
We cover hardware to cloud — one team handles your sensor nodes, backend API, web dashboard, and mobile app. No coordination overhead between vendors.
Production-Ready, Always
We build systems that hold their ground under real load. No experimental prototypes — every delivery is tested, monitored, and ready for production traffic.
Built for East Africa
M-Pesa integration, low-bandwidth optimization, regional compliance, and local infrastructure knowledge baked in from day one.
Post-Launch Partnership
We stay engaged after launch — monitoring dashboards, incident response, and iterating based on real usage. Your system improves over time.
Hardware to Cloud
From Arduino sensor nodes to cloud telemetry pipelines — we architect the full physical-digital stack when your problem requires it.
What clients say. In their own words.
“Yahventech turned our rental business from WhatsApp chaos into a real marketplace. We launched with verified listings and M-Pesa payments from day one — tenants and landlords finally trust the platform.”
“Reporting used to take the team two full days every month. Now it takes fifteen minutes, and every branch sees live stock. The CRM paid for itself within the first quarter.”
“We went from reacting to complaints to seeing every floor in real time. The alerting alone has cut our incident response time in half.”
Notes from the engineering floor.
How we build rental marketplaces that work in East Africa
M-Pesa-first payments, low-bandwidth design, and trust mechanics: the practical choices behind Rentopia.
From spreadsheets to CRM — without the migration headache
The FortuneMotors CRM replaced disconnected Excel files. Here’s the migration approach that kept the business running.
IoT building monitoring that runs on less than 5 watts
How HMS uses ESP32 sensor nodes, MQTT, and InfluxDB to give a building real-time awareness — cheaply.
