Professional profile

Precision-driven.
Security-minded.

I am a Full-Stack Developer and Cybersecurity Specialist with a background spanning software engineering and high-stakes operational technology. Before transitioning into software, I spent over a decade managing precision IoT systems and large-scale operations — work that demanded engineering discipline and consequence-awareness most developers only encounter through hard experience.

I founded and built an online pharmacy platform from scratch — architecting every layer from frontend to payment systems to security hardening and CI/CD pipelines. That project validated a security-first engineering approach in production: zero security incidents, 99%+ uptime, handling regulated pharmaceutical data at scale.

I hold all the academic and professional qualifications required for this role, and continue developing expertise in applied cybersecurity through directed study aligned with OWASP standards and current threat research.

Experience & Education

A career built on systems that cannot afford to fail — from regulated HealthTech platforms to large-scale industrial operations.

Work Experience
2024 – Present
Co-Founder & Full-Stack Developer
Family DrugMart Kenya — Online Pharmacy & HealthTech familydrugmartkenya.com ↗
  • Co-founded and designed the full e-commerce platform for an online pharmacy and ultrasound scanning service operating in Nairobi, serving customers across Kenya.
  • Built the complete website — product catalogue (400+ pharmaceutical products), prescription submission workflow, online ordering, and payment-on-delivery system.
  • Implemented secure user accounts, order management dashboard, and admin backend enabling the business to operate with minimal manual intervention.
  • Platform has been live and operational since 2024, delivering medications within 4 hours across Nairobi and 12–24 hours nationwide.
Sep – Nov 2024
IT Support Intern
National Broadcaster — Broadcast Technology & IT Infrastructure
  • Maintained mission-critical broadcast infrastructure, ERP, and HR systems under live-transmission conditions.
  • Produced technical documentation that measurably reduced repeat incident escalations.
2019 – Present
Freelance Full-Stack Developer & IT Consultant
Independent — Various Clients & Industries
  • Delivered 100+ freelance IT projects across web development, system design, database engineering, cybersecurity, and technical consultancy.
  • Clients span healthcare, education, agribusiness, retail, and media sectors.
  • Project details withheld by client confidentiality agreements — references available upon request.
2019 – 2020
Irrigation & Pump Systems Technician
Agro Irrigation & Pump Systems — Kajiado, Kenya
  • Performed service and maintenance of Gavish computerised irrigation control systems — the precision technology used to ensure crops receive the exact right quantity of water and nutrient-rich solutions at the correct intervals.
  • Operated and maintained a Reverse Osmosis (RO) water treatment plant — essential in Kajiado due to the region's naturally hard, mineral-heavy groundwater, which must be purified before it can be used in sensitive irrigation systems.
  • Carried out pump maintenance, fault diagnosis, sensor calibration, and system configuration across commercial greenhouse and field operations.
2011 – 2019
Fertigation Technician
Suera Flowers Ltd — Export Floriculture, Nyahururu, Kenya suera.co.ke ↗
  • Operated the computerised fertigation feeding machine — a precision system managing the delivery of exact nutrient solutions (fertilisers dissolved in water) to rose crops, critical to producing the export-quality blooms that Suera supplies to markets across Europe, Russia, and worldwide.
  • Suera Flowers is one of Kenya's leading rose exporters, located in Nyahururu near Thompson Falls at 2,300m altitude. A family company founded in 1996 and a Kenya Flower Council member, Suera grows roses across 30+ hectares to European non-hazardous chemical standards.
  • Maintained dosing accuracy, monitored EC/pH levels, adjusted nutrient programmes in collaboration with the farm agronomy team, and ensured zero disruption to feeding schedules across 24/7 growing operations.
