My work experience began in embedded software development for home automation systems - C programming, microcontollers (PIC, Atmel AVR and STM32s), real-time operating systems, API design and communication protocols. Since then I have developed embedded software for a variety of applications - for both hobbyists and small companies. I have meaningful experience with server-side development and relational databases also - in Perl, Python and PostgreSQL primarily. I have a first-class Bachelors degree of Electrical & Electronic Engineering. To students / interns: I am happy to offer tuition, but I am not willing to facilitate plagiarism under any circumstances - so don't ever approach me asking me to do your project for you. Note: Don't take my hourly rate seriously. It may be (significantly) more or less depending on the job. I sometimes take on small jobs - partly to boost my knowledge in a particular technical area, partly for fun. Even if I manage to deliver such projects at a relatively low cost, please note that this is not necessarily indicative of my usual hourly rate. I'm not obliged to offer the same 'low-cost' terms to everyone I work with.

Very thorough and responsive, communicated well and understood the requirements and outcome was different but much better than initially envisaged.

Very bad behavior, attitude and manner. Will not recommend. Did not solve the issue. Very bad freelancer.

Implementation of a GSM communications gateway for an embedded system; a complete implementation of the DEX vending-machine protocol on 16-bit PIC microcontrollers. I also introduced the company to low-cost 3D printing - the fused-deposition modelling (FDM) process specifically. We are currently building a newer and faster version of these machines based on inverse kinematics - a type of delta robot essentially.
