Combining AI agents, IoT ecosystems, embedded firmware, engineering simulations, and full-stack software into solutions that actually move the needle.
What I Build
From embedded firmware to cloud-connected AI — I work across the full stack of intelligent systems.
Custom LLM-powered agents, WhatsApp automation bots, intelligent workflows, and NLP pipelines tailored to your business logic.
ESP32/Arduino firmware, MQTT messaging, real-time telemetry dashboards, sensor networks, and cloud data pipelines.
Low-level C/C++ firmware, RTOS integration, peripheral drivers, and hardware-software co-design for production devices.
Control systems design, robot kinematics, PLC automation, and industrial process automation with SCADA integration.
SolidWorks 3D modelling, FEA analysis, MATLAB/Simulink control system simulations, and technical documentation.
React, Flutter, Node.js — scalable, production-grade digital products with clean architecture and CI/CD pipelines.
Portfolio
Real clients. Real problems. Real outcomes — not just pretty websites.
Full institutional website with student portals, course catalogue, and online enquiry workflows for a vocational training institution in Zimbabwe.
Engineering and skills development centre with a full website, course management backend, and WhatsApp inquiry integration.
Premium auto detailing brand with a conversion-focused website, online booking system, and service showcase gallery.
Courier and logistics platform with route-based quote calculator, package tracking integration, and WhatsApp customer handoff.
Deep Dives
Technical problems, the approach taken, and measurable results.
Problem
Smallholder farm losing yield to over/under-irrigation with no real-time visibility into soil conditions across multiple fields.
Solution
Deployed 12× ESP32 soil-moisture nodes with MQTT telemetry, a Node.js dashboard with alerts, and automated irrigation relay triggers.
Stack
ESP32 · C++ Firmware · MQTT · Node.js · React · InfluxDB · Raspberry Pi Gateway
Problem
SME losing leads after hours because no one was available to respond to WhatsApp inquiries promptly.
Solution
Built a WhatsApp Business API agent with GPT-4o backend, FAQ knowledge base, lead capture form, and CRM webhook integration.
Stack
WhatsApp Business API · GPT-4o · Node.js · Supabase · n8n workflows · Twilio
Problem
Engineering firm needed a precision bracket assembly CAD model with FEA stress analysis before committing to tooling costs.
Solution
Full SolidWorks parametric model, assembly drawings, BOM, and MATLAB stress simulation report delivered in 10 days.
Stack
SolidWorks 2023 · MATLAB R2023a · FEA Simulation · Technical Drawing Package

Social Proof
"Takunda built our college website from scratch. The project was delivered on time, fully mobile-responsive, and the WhatsApp integration has genuinely changed how we handle enquiries."
"The IoT monitoring system Takunda designed for our farm operations helped us understand exactly where water was being wasted. The dashboard is clear and the hardware has been running reliably."
"The SolidWorks models were production-ready on the first submission — clean drawings, proper tolerances, and a detailed BOM. Saved us weeks of back-and-forth with the manufacturer."
