Cesar T.

I build production-grade Python software and analytics tools for energy companies — from technoeconomic simulation platforms to real-time grid operations systems and industrial leak detection pipelines. Over 5+ years I've worked directly with renewable energy developers, grid operators, EV infrastructure teams, and industrial monitoring companies. My work shows up in capital allocation decisions, operational dashboards, and contract management systems — not just Jupyter notebooks. What I deliver: Technoeconomic Modeling Financial simulation engines for solar PV, wind, and battery storage assets — modeling degradation curves, multi-scenario projections, financing structures, NPV/IRR, and capital planning. Built for project developers, investors, and asset managers who need defensible numbers. Energy Data Analytics End-to-end analytics pipelines: sensor data ingestion, anomaly detection, time-series analysis, and operational dashboards. I've built leak detection systems for industrial infrastructure and real-time decision-support tools for plant operators managing interconnection agreements and price exposure. Software Development Clean, extensible Python systems backed by MongoDB, PostgreSQL, or SQL Server. I design for maintainability — not just to get the feature out the door. Past work includes OOP simulation engines, REST APIs, ETL pipelines, and Plotly/Looker dashboards. Advisory & Consulting Early-stage scoping, architecture reviews, and feasibility analysis for energy software projects. Useful if you're deciding whether to build vs. buy, selecting a tech stack, or trying to understand what a model is actually telling you.
