Front-end (React) software engineer with some experience in full stack development too (TypeScript all the way browser to Node). Also did very substantial GIS (front-end) work having developed the entirety of the front-end GIS code (and most of the CRUD code) for a major goverment system that saw heavy production use: the nationwide system where farmers apply for EU agricultural subsidies (importing, exporting and drawing on the browser all sorts of polygons and other non-area geometries to represent various concepts relevant in the domain plus topological calculations).

Co-founded Semantix 2001 (merged with Neuropublic in 2011) and have worked for the European Space Agency and as full time employee in the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA (4 years each).

games and frivolities I've developed in React (tested on Chrome — should be played with sound for best experience)

• Games:
• Catch the Lion (click to play)
  • github repo for the main game
  • github repo for the AI library (based on the Minimax algorithm)
  Note: Around 2018 I released minmax-wt-alpha-beta-pruning which is a much improved (over the above version), generic (can be used with any game) implementation of the minmax algorithm that employs the alpha-beta pruning optimization. In contrast, the AI library for this game does not perform alpha-beta pruning and, most importantly, does not cleanly separate the minmax algorithm from the game rules and game state evaluation logic that's specific to this game. It also fails to quickly recognize victory end states and foolishly waits until all other game tree leaf nodes are evaluated (the alpha-beta optimization addresses that, among other things). Future games will be based on my new minmax library.
• Tetris game (click to play)
  • github repo
• Minesweeper game (click to play)
  • github repo
• Algorithm visualizations:
• Stacks of grain piling and tumbling
  • github repo
• Implementation and demo of the cubehelix algorithm (ReactJS)
• Towers of Hanoi (ReactJS)

Using the Canvas API:

• Space invaders game (click to play) (next: add ammo-packs, wave attacks and new weapon types)
  Note: Disavowed — except for the failure message for which I am proud.

• project Euler solutions in JavaScript (Node.js)

What follows is a motley crew collection of TILs and notes that've accumulated, or rather hoarded, over the years (in the pre-LLM days) and neurotically documented here for the dubious benefit of my future self (and, as such, unlikely to be useful to anyone else and very likely to be harmful considering deprecation over time)).
