About

Multi-disciplinary engineer building solutions that last.

I hold a BSc in Agricultural & Biosystems Engineering from JKUAT and a CCNA in Enterprise Network Security & Automation. My career spans water infrastructure, environmental assessment, structural inspection, mechanical engineering, and IT — bridging technical depth with community impact across 8+ counties in Kenya.

I've delivered projects for the World Bank, UNHCR, Concern Worldwide, Church World Service, World Vision, and the National Irrigation Authority — always on time, within budget, and to international standards.

Ministry of Water, Sanitation & Irrigation  ·  SMEC International  ·  Ref. MWSI/WTR/PS/7/VOL.11(78)
Member of a multiagency forensic team — structural engineers, mining/explosives expert, quantity surveyors — commissioned by the Ministry of Water to investigate community complaints of blast-induced structural damage caused by contractor China Gezhouba Group Company Limited (CGGC) during Phase 1 of Kenya's flagship Vision 2030 Thwake Dam. The assessment was a critical gate for African Development Bank Additional Funding approval, escalated by the Ministry Project Engineer directly to SMEC's Authorised Representative.

⚠ Key Findings
>70% of walls used soil mortar — below KS 2801-1:2019; fired brick ≥150 mm highly susceptible to cracking under combined settlement + vibration
Cracks: 0.5–16.4 m per structure; 1–9 individual cracks per element. PPV <5 mm/s can still cause visible cracking on fragile red-soil masonry
CGGC withheld initiation plans & emulsion data — causation inconclusive; AfDB funding contingent on CGGC providing complete blasting data

Pyro-Plasma Hydrogen Formation Bench Scale Chamber — Final Year Thesis
📍 JKUAT, Nairobi · May – Nov 2022
Designed, fabricated, and tested a bench-scale plasma pyrolysis system for CO₂-free "turquoise hydrogen" production from biomethane. Achieved 21% methane-to-hydrogen conversion efficiency on a prototype built under significant cost and time constraints. System components included a TIG plasma torch (argon carrier gas), plug-flow reactor (ceramic blanket + refractory cement insulation), cyclone separator, and copper-coil condenser. Process optimised using ANSYS CHEMKIN kinetic modelling and Aspen Plus simulation — aligned with SDG 7 (Clean Energy) and SDG 13 (Climate Action).

Design & Implementation of a Pyro-Plasma Hydrogen Formation Bench Scale Chamber
Jomo Kenyatta University of Agriculture & Technology (JKUAT) · May – November 2022
A full-cycle engineering research project exploring turquoise hydrogen production — a CO₂-free pathway where methane is thermally decomposed into hydrogen gas and solid carbon black, with no greenhouse gas emissions. The work was motivated by the JKUAT PEMFC (Proton Exchange Membrane Fuel Cell) project, which needed a viable sub-system for on-demand hydrogen supply that commercial procurement and water electrolysis had both failed to deliver. The bench-scale prototype addressed this gap while contributing to the global transition toward net-zero energy systems, aligned with SDG 7 (Affordable & Clean Energy), SDG 9 (Innovation), and SDG 13 (Climate Action).
  • Performed thermodynamic and Gibbs free-energy mathematical modelling to determine equilibrium conditions and Specific Energy Requirements (SER = 37.7 kJ/mol H₂ — ~40% more efficient than steam methane reforming)
  • Developed kinetic and process models using ANSYS CHEMKIN and Aspen Plus to predict reactor behaviour and optimise process parameters before fabrication
  • Designed all system components in SolidWorks CAD: plug-flow reactor (Ø110mm × 1200mm mild steel, 34mm ceramic blanket + refractory cement insulation), rapid cooling chamber, cyclone separator, copper-coil condenser
  • Selected TIG welding torch (argon carrier gas, arc temperature ~2500 K) as the plasma source over plasma cutter — superior inertness, better arc control, no HCN formation risk
  • Fabricated and assembled the full prototype using TIG welding, sheet-metal rolling, refractory casting, and brazing — working within tight budget and a 6-month academic timeline
  • Achieved 21% methane conversion efficiency on bench testing, confirmed via Gas Chromatograph analysis of inlet biogas vs. product gas samples
  • Recommended solar-powered energy supply integration for scale-up to reduce electrical grid dependency and further lower the system's carbon footprint toward fully carbon-neutral operation
