Software for a prototype 360° image capture system (2014)

Software for Linux-based SBC, controlling DSLR (entering required settings, triggering shutter, feedback about battery etc) and controlling digital-communication servo motors.

RepRap2X (2014)

I've built a few RepRap 3D printers in the last few years (original Mendel, two Mendel90) and I wanted a larger, more rugged printer, which Just Prints.

Mechanical design in CAD (SW), mechanical re-design (hehe), assembly, wiring, configuration. Auto bed-leveling calibration (still somewhat in progress).

Desktop CNC engraver (2013)

Wanted a mill, got an engraver. Designed in CAD, inspired by designs on internet. Now has gotten a proper spindle and is even usable for light machining work: Dibond, plastics, PCBs.

Postal package tracker (2013)

A web-based tool to notify me when my stuff arrives in local post office. Written using Django, scrapes pasts.lv for the data on packages.

CNC plasma cutter - software and motion control (2010)

Dad built a CNC plasma cutter, I brought it to life- simple as that. Upgraded to custom-built torch height controller in 2014.

Web-app company - groupscript.net (2010 - 2014)

Co-founded a company which sold PHP e-commerce software mostly authored by me.

My role could be described as lead-developer who also got to manage a team of 5 other developers.

Experience gained: immense knowledge of web payment systems, how to write PHP software to be hosted on myriad of web-servers out there and how not to write an e-commerce software.

Got to build in-house tools for order processing, release packaging etc.
