// featured projects

Baseline — ATP tennis match predictor Jun 2026 – Present
Founder & ML Developer · baseline.n0.nu
  • Built an ATP match-prediction model on custom-engineered features, beating a pure-Elo baseline on accuracy (65.4% vs 62.7%) and brier (0.216 vs 0.225) with walk-forward validation and no future leakage.
  • Designed a custom Elo system with general and per-surface tracks, a tournament/round-weighted K-factor, and month-prorated decay toward 1500 so inactive players regress to the mean.
  • Built a "panic" clutch score in [0,1] from break-point stats and match length, with a loser-floor constraint so a winner can never look more panicky than a loser.
  • Deployed a live Streamlit site with a leaderboard, match predictor, and live ATP predictions from Sofascore, plus an accumulative archive that grades past predictions.
B2B management & analytics ERP Mar 2025 – Present
Lead Backend & Data Engineer · startup in development
  • Designed the backend architecture of an ERP based on a universal data model structured around a fixed table schema, industry-agnostic, to enable fast deployments.
  • Optimized the data model in PostgreSQL and SQLite to support high information density and enable real-time Business Intelligence integrations.
  • Developed the RESTful API with FastAPI, building the business logic that operates over the fixed-table model with minimal response times.
CiceronIA — First Prize, Reto Fest (UPCT) Nov 2025 – Apr 2026
AI Backend Developer
  • Co-developed "CiceronIA", an AI tool that assists judges in debate competitions through multimodal analysis. Awarded First Prize at the UPCT Reto Fest.
  • Built the backend infrastructure with FastAPI and orchestrated the natural language processing (NLP) models using LangChain.
Hearer AI — AI note-taking tool Mar 2024 – Feb 2025
Founder & Full-Stack Developer · hearer.n0.nu
  • Developed a web application that generates personalized notes from class and meeting audio.
  • Designed and implemented the full platform, integrating AI models for audio processing and text generation.
