I design and deliver electrical control systems for highly regulated medical and pharmaceutical equipment — from schematics and control panels to PLC programming, HMI/SCADA and instrumentation, all built to international standards.
Electrical and Electronic Engineering graduate with proven expertise in analysing electrical and electronic circuits and PCB designs using simulation software such as Multisim, Proteus, Altium and KiCad. I design analogue and digital circuits, signal amplification and filtering, switch-mode power supplies, and perform PCB reverse engineering.
I am proficient in technical drawings and schematics using AutoCAD Electrical, PC Schematics and EPLAN, and I create and read power distribution and pneumatic schemes. I design and build electrical panels, then program and commission the control systems — backed by strong research, development and project-management skills.
A blend of hands-on hardware, control engineering and software, applied across industrial automation projects.
Selected engineering work across industrial control, electronics, embedded systems and R&D — including custom PCB designs with downloadable schematics.
Designed and programmed Siemens PLC systems for containment and clean-air machinery used in regulated medical and pharmaceutical industries, with user-friendly HMI for monitoring and configuration.
Created detailed wiring schematics and instrument schedules compliant with IEC 60204-1, BS 7671 and BS EN 61010, including cable-sizing and intrinsically-safe calculations.
University project developing a precision measuring device for railway wheel profiles, combining sensor instrumentation with data acquisition and analysis.
Research project transmitting data over visible light using an LED transmitter and photodiode receiver, exploring high-speed optical communication.
Graduation project at CNAQ implementing a dual-axis sun-tracking controller to maximise photovoltaic energy capture through automated panel positioning.
Built home-security solutions using Raspberry Pi and an award-shortlisted Arduino GSM system with motion sensing, keypad access and remote alerting.
Custom KiCad-designed PCB that conditions and amplifies the Hall-effect tachometer feedback from an EC fan. A 24 V supply is regulated to 5 V (LM7805) and an LM358 op-amp stage with gain/offset trimming delivers a clean signal to the controller. Designed at ENVAIR Technology.
Custom serial communication interface built around a PIC microcontroller and an RS-485 transceiver, providing robust half-duplex differential comms over long distances with USB connectivity, keypad input, status LEDs and an in-circuit programming header — ideal for Modbus/RS-485 device networks.
A set of interactive electrical & electronics calculators I built for everyday design work — standard resistor selection, voltage/current dividers, BJT switch design, RC filter sizing and BS 7671 cable sizing / voltage drop. All calculations run instantly in your browser.
Enter a target resistance and the calculator returns the closest value in the selected E-series, with the percentage error.
Select the colour of each band to decode the resistance and tolerance.
Vout = Vin · R2 / (R1 + R2). Enter the supply and both resistors.
Two resistors in parallel. I1 = Itot · R2/(R1+R2), I2 = Itot · R1/(R1+R2).
Sizes the base resistor to drive an NPN transistor into saturation for a given load. Uses an overdrive factor for reliable switching.
First-order RC filter. fc = 1 / (2·π·R·C). Leave one field blank to solve for it.
BS 7671:2018+A2:2022 flat twin & earth (copper, 70°C PVC). Recommends the smallest cable that carries the load and stays within the voltage-drop limit. VD = (mV/A/m × Ib × L) / 1000.
Lead the electrical design and delivery of standard and bespoke containment and clean-air equipment. Develop schematics and functional design specifications, write Siemens PLC programs and HMI interfaces, and support panel build, FAT/SAT and field engineers.
Built electrical panels and PLC programs, tested instrument hardware and software, performed technical analyses and engineering reports, and supported systems testing and factory acceptance testing across sites and the workshop.
Installed, maintained and upgraded internet cabling, routers and TV equipment; tested signal strength and resolved losses using electronic test equipment.
Supported instructors and students in electrical/electronic labs, troubleshooting devices, soldering and preparing PCBs, and managing components inventory and procurement.
Power and control engineering, advanced analogue/digital electronics, microcontroller programming, communications and networks, with an individual research project.
Networking and communications technology covering fibre optics, embedded microcontrollers, transmission systems, and the Cisco Networking Academy programme.
Design, installation and support of switches, routers and VLANs; LAN/WAN troubleshooting; TCP/IP, subnetting, VPN and QoS concepts.
