Roshan Kumar Jha

I’m a full-stack software engineer with production experience across ERP systems, mobile apps, REST APIs, and AI/ML pipelines. I thrive on strong engineering fundamentals—system design, unit testing, and CI/CD—while delivering in Agile sprints. I’m also a published ML researcher (JETIR, Dec 2025), which keeps my work grounded in rigorous experimentation.

As an Applied Machine Learning Intern, I built a Python-based experiment tracking system for dataset versioning, model configs, and run history, cutting manual tracking effort by ~60%. I also designed a modular batch + REST training/evaluation pipeline with structured logging and deterministic configs to make ML iterations fully reproducible. On top of that, I wrote unit and integration tests for ML workflows and added lightweight performance benchmarks before production handoff to reduce post-release regressions.

Before that, as an Application Developer Apprentice, I led the revamp of a production web ERP and shipped its Android companion app. I built Flutter (Dart) mobile screens wired to 10+ REST API endpoints, improving perceived load time by ~30% through optimized response mapping and client-side caching. I also tightened validation and error handling across web and Android, reducing user-reported bugs by an estimated 40%, and I backed the impact with end-to-end multi-module feature releases and documentation.
