Where research meets working software.

I am Rijusmit Biswas. I work as a software and machine learning engineer, and I enjoy the stretch between an idea that might not pan out and something people can actually depend on.

I am in my final year of a computer science degree at IIIT Delhi and I graduate in September 2026. I like building the whole thing: the screens people click, the API behind them, the database under that, and the servers it all runs on.

So far I have taken a product from a rough idea to something live on AWS, moved a running system onto a new stack without anyone noticing an outage, and built a portal that more than 500 students use. I designed its database and the API the rest of the team builds against. I also look after the quieter parts that keep software healthy, like containers, tests and checks that run on every pull request, sensible retries, and logs you can actually read.

On the research side I have shipped machine learning that people keep using. My lab still runs an evaluation tool I built to catch when a model starts giving worse answers. Before that I built satellite imagery pipelines for predicting crops and measured how much the models slip from one district to the next. I am the first author on a paper about that work, under review at AAAI 2027 (title withheld until review is complete).

I also built a cross-portfolio credit risk system predicting defaults on credit cards and installment loans (XGBoost 0.7769 ROC-AUC, $18.7M estimated savings), a 7-agent swarm that runs a private executive job search offline, and a distributed creator platform with GraphQL federation. I care about the craft: clean boundaries, observable systems, and code that survives contact with production.
