Status: Open for interesting project - drop me a line about your needs

I have 30+ years of experience in software development.
During those years I coded in many different, sometimes obscure, languages: machine code, assembler, C, C++, Pascal, Basic, .NET, PHP, game engines and many others.

Now I work mostly in Python/Django. I am kind of full-stack developer, good at database design, connecting unconnectable things, solving problems and making things work.

Current tech stack: Python, Django, Flask, *SQL, Bash, React, GIT, HTML, CSS, Bootstrap, Docker, basic sysadmin tasks.

Languages: Czech, English (fluent), Spanish (A level).

Some projects I worked on:

D.A.S legal insurance company - I worked both on external (e.g. sales) and internal systems. The internal system for handling issues was tremendous amount of hard work: tons of different workflows, integration with other systems and data. Plenty of data.

Výstaviště - There is some kind of reservation system on that site, calendar, activities… - a lot of BE stuff, actually

T-business - I contributed to backend and some CI.

Silent lab - There is entire catalog of products and accessories on that website.
I worked on backend, building administration and underlying data structure from scratch.

GreenOrDie.org - Data project, counting CO² emission for various pollution sources. Django based in early stage of development.

Dispatcher - Industrial system for controlling production and dispatch of the concrete. Browser based DB application. Python backend (ORM, Flask), Javascript (+JS framework) frontend. Used by major concrete producers in Czech republic.

CRM system - nalodeni.pirati.cz - I did some work on CRM system for the Czech Pirate Party. The entire thing was broken, with half-written features, nonexisting bug tracking and so on. I refactored 90% of the code, managed hundreds of untracked user requests, did some integrations and fixed plenty of bugs. Still not a state of the art, but a fine example of taking over the messy project and turning it into something that works.

Payment tracking system for non-profit organization Otevřená města. It was a “make it work” kind of gig. They had some system and needed to rebrand it, make some tweaks, modify data model to fit into their organization scheme, and, finally, connect the entire beast to the 3rd party SSO provider (MojeID).
Update: the system is not public anymore, so you can’t see it in action.

Playing with Copernicus: with gigabytes of satellite imagery, available via project Copernicus, you can see a lot on the surface of our mother Earth. Using Python, I processed satellite images with some basic AI, and played with generating timelapses. It is kind of work I do for fun, those two examples took one afternoon each.

Bluetooth RSSI scanner - opensource simple CLI tool to display nearby Bluetooth devices and monitor signal strength (RSSI). Curiously, I couldn’t find anything handy. So out of desperation I finally forked an older tool and enhanced the functionality. Repo here: https://gitlab.com/Jarmil/btscan
