Full-stack + data science: building data-heavy products end to end
About
Hi, I'm Sonali. I'm a full-stack engineer and data scientist with 5+ years of experience building data-heavy products end to end, from system design and backend architecture to cloud infrastructure and production support.
I started as a founding engineer, taking a product from zero to app-store launch. Since then I've led engineering for new product launches and built the data layer behind them: scoring engines, ML models, and report pipelines that turn raw data into something people can act on. I also have an M.Sc. in Mathematics from IIT Gandhinagar, which shapes how I think about modelling and evidence.
**What I write about**
- Designing data pipelines and scoring systems that hold up in production
- Applied statistics and ML, with the maths explained properly
- Full-stack architecture decisions and the trade-offs behind them
- Lessons from building and shipping real products
**My stack:** TypeScript, Node.js, React / React Native, Python, R, SQL, AWS.
