Hi, I'm Smrity Mallik

Mechanical Engineer · MSc AI & Data Science @ Gisma Berlin
Machine learning, simulation and energy systems · Published researcher · Berlin


About me

Interdisciplinary engineer bridging mechanical systems and AI. I turn complex engineering data into clear, actionable insights using data science, machine learning, and digital tools. I report results honestly: baselines, held-out tests, confidence ranges, and each model's limits.

  • MSc AI, Data Science & Digital Business: Gisma University of Applied Sciences, Berlin (2025- 2027) with MSc International Business Management, Kingston University, London
  • BE Mechanical Engineering: Savitribai Phule Pune University (2022- 2025)
  • Interned at Thermax Ltd and Kirloskar Pneumatic
  • Published and presented at the RDME-2025 national conference
  • Based in Berlin, Germany
  • English · Hindi · German (A2/B1, improving)

Featured projects (each with a live, interactive demo)

1. TrustRUL: jet-engine remaining life with a trustworthy confidence range

NASA C-MAPSS turbofan data. GRU and XGBoost with proper baselines, conformal prediction (calibrated margin of error), SHAP, MLflow tracking, a model card, and a 3D maintenance simulation where you decide when to pull engines. Live demo · Code

2. Rice straw boiler: efficiency model (final-year project, with Thermax)

Indirect heat-loss model of a biomass boiler, validated against the design workbook (81.3% at the design point), with sensitivity ranking, Monte Carlo uncertainty, and a 3D simulator of the plant and its internal flow. Live demo · Code

3. Redispatch analysis: cost of German grid congestion

Cost and volume of redispatch 2022€- 2026 with bootstrap trend tests (cost per MWh fell about 12 % a year; the volume change is not clear), a Power BI data package, and a grid-congestion simulation graded against the exact linear-programme optimum. Grid simulator · Code

4. Energiewende in the Bundestag: German NLP on energy debates

1,161 speeches (2009€- 2021): topic modelling with LDA, BERTopic and GBERT, a spaCy entity pipeline, theme trends with session-bootstrap ranges, and an in-browser party model. Live demo · Code
