Scouting report

Algorithms-minded backend developer across several languages

assessed from open-source footprint

Mid
34signal

Yeiniel works across C#, C++, Java, and JavaScript, with a clear leaning toward fundamentals — one repo collects binary, ternary, interpolation, exponential, and linear search implementations. Seven original repos and a long-lived account suggest sustained interest, and a personal blog points to writing alongside code. That said, stars are minimal (four total), everything is marked abandoned, and there are no commits in the past year, so momentum is the open question. Solid grasp of algorithmic basics; the profile needs fresh, maintained work to show current depth.
