Chi sono
I help businesses and individuals with Python scripting, SQL queries, and cleaning up messy data. Whether it's fixing broken spreadsheets, writing custom SQL for your database, automating repetitive tasks, or pulling data from APIs, I get it done accurately and on time.
I'm also experienced in building ML/NLP systems — including RAG pipelines and transformer fine-tuning — so if your project needs something more advanced down the line, I can help with that too.
Clear communication, fast turnaround. Happy to discuss your requirements before you order so we're both clear on scope.

Company: IDCUBE Identification Systems. Worked on end-to-end data and ML systems for enterprise dashboards. Built a RAG-based chatbot (Aisha) that lets users ask questions in plain English and get answers pulled straight from company data — used across 9 dashboards. Designed an anomaly detection system that scores risk across 45+ parameters for a vulnerability tracking tool. Improved query performance on a dashboard handling 14M+ records, cutting response time in half through a better pagination approach. Also built REST APIs for a real-time data pipeline — pulling in raw data, cleaning and transforming it, and loading it into the target system.
