Hello,
my name is Calancea Daniel. I have worked at Lightcyphers, but because of project shortages, I had to leave the company. Currently I am searching for a position as elixir developer, however I was not able to get a decent response from any companies I’ve applied to.
I have 4 years of experience of developing/architecting/deploying libraries and servers in elixir/erlang. Because there are very few elixir developers, I also taught complete novices elixir and its philosophy and managed their progress.
The list of projects I participated to are:
- Tachowork; a platform for downloading and managing tachocards and tachograph downloads. This project was fully architected by me and mostly developed by me as a prototype. The platform included a lot of components such as: custom electronics for downloading from tachographs, android application with custom drivers for communication with usb smartcard readers, a backend for users developed with elixir and liveview that also had a fully fledged role access system made from scratch, a parser for parsing DDD files using elixir and metaprogramming.
- Prototype project using postgis/maplibre with liveview; In this project a prototype was developed for detecting telecom frauds in realtime on map, all the data was collected/processed using postgres and geometries generated using postgis, map was powered by maplibre-js.
- Fraud detection system; This was the last and hardest project, the task here was to stabilize and improve a fraud detection system. The system requirements were what the erlang runtime shines: uptime 99.999% and soft realtime. This project involved a lot of postgres optimizations and migrations in a running production environment with minimal downtime. A lot of migrations tasks were done by using the new livebook, connecting it to the production server.
As of open-source, the biggest project I managed to accomplish was to run a elixir project on android. This was accomplished together with JeromeDeBretagne and it included fixing the build process for arm64 on android, creating new instructions on how to build and link openssl for android build, changing how otp release finds the relative path for binaries. After doing all that I was probably the first person to successfully start a phoenix server on android without superuser requirements.
I’ve tried to apply to multiple companies (most of them from elixirforum), however I was not even able to even receive a response from most of them, and I cannot locate the root of the problem of why this happens.
Here is my resume, I use it to apply for elixir jobs, it includes the practical skills that I’ve developed while working with elixir/erlang.
If you have time to review, and come with feedback, I would appreciate it very much.
Have a nice day,
Daniel
