Engineering at Tech-Stun
Engineering scalable,
secure, and intelligent systems.
From architecture to deployment, we build systems designed for performance, security, and scale. Not just code — engineered solutions.
How we think
Engineering philosophy.
Every decision we make — from database schema to deployment strategy — is guided by these principles.
Scalability-First Design
We design for 10x traffic before we write the first line. Architecture decisions are made with growth in mind, not afterthought.
Security by Default
Security isn't a feature — it's the foundation. Every system is hardened, every input validated, every endpoint protected.
Performance Optimisation
Sub-100ms API responses. Optimised queries. Smart caching. We don't ship slow systems.
Clean, Maintainable Code
Code is read far more than it's written. We enforce standards, write tests, and document decisions.
API-First Architecture
Every system we build exposes a clean, versioned API. Integrations are first-class citizens, not bolt-ons.
Intelligence at the Core
AI isn't added later — it's designed into the system from the start. Our pipelines are built to learn and adapt.
Technical domains
Core capabilities.
Six engineering disciplines, one integrated team. We don't silo — your backend engineer understands the frontend, and your ML engineer understands the infrastructure.

POS + eTIMS Integration
Real-time tax compliance pipeline for multi-branch retail POS systems.
How we work
Engineering process.
A repeatable process built for quality. Every project — from a two-week POS deploy to a six-month AI system — follows the same rigorous path.
Discovery & Requirements
We embed with your team to understand the real problem — not just what you asked for, but what you actually need.
System Design & Architecture
We design the full system blueprint before writing code — data models, API contracts, service boundaries, and scaling strategy.
Development
Iterative sprints with daily standups. Clean commits, peer-reviewed PRs, and continuous integration from day one.
Testing & QA
Automated unit, integration, and end-to-end tests. Manual QA on every release. Nothing ships without a test suite.
Security Hardening
Every release goes through a security checklist — OWASP top 10, dependency audits, penetration testing on critical systems.
Deployment & Monitoring
Zero-downtime deployments. Real-time error tracking. Uptime monitoring. We own the system until it's yours.
Our arsenal
Tech stack.
Battle-tested tools chosen for performance, reliability, and developer experience. No hype — just what works.
Proof of work
Engineering wins.
Real problems. Real architecture. Real outcomes.
Pharmacy POS with eTIMS Integration
Problem
A multi-branch pharmacy was failing KRA audits and losing KES 200K/month in compliance penalties.
Solution
Designed a distributed POS architecture with real-time eTIMS sync, offline-first mode, and automated tax reporting.
Outcome
Zero compliance penalties in 12 months. 99.8% uptime. 40% faster checkout.
AI Fraud Detection Pipeline
Problem
A SACCO was losing KES 5M/year to fraudulent transactions slipping through manual review.
Solution
Built a real-time ML pipeline that scores every transaction in under 30ms using anomaly detection and behavioural models.
Outcome
94% fraud detection accuracy. KES 4.2M saved in first year. Zero false positives above threshold.
Hospital Lab Management System
Problem
A 200-bed hospital was managing lab samples on paper, causing 3–5 hour delays and frequent result mix-ups.
Solution
Built a full digital LIMS with barcode tracking, automated result entry, audit trails, and role-based access.
Outcome
Result turnaround cut from 4.5hrs to 47 mins. Zero mis-labelled samples since launch.
