Engineering_Logs
Technical write-ups on autonomous intelligence and backend architecture. Featuring the 'Evo-Sim' and 'TTMC' project logs.
A hungry evening turned into a masterclass on Queues, Stacks, Arrays, and Graphs as I observed the quiet algorithms of a local diner.
Exploring layered security by combining Transposition and Modified Caesar ciphers into a modular Python cryptographic library.
Most simulations look deterministic. Evo-Sim feels different—search for food, spend energy, reproduce, mutate, and watch natural selection take over.
