Hi, I’m Mark
I'm an ML Engineer at 314e Corp in Bengaluru, where I build and operate MLOps pipelines for healthcare ML systems — orchestration, distributed data processing, and model serving at scale. Outside of work I write low-level Rust and Python for fun: reimplementing NumPy from scratch, and building terminal tools I actually use every day.
Experience
314e Corp Current
Data Science Engineer (Jan 2025 – Present) → Associate Data Science Engineer (Dec 2024 – Jan 2025) → Data Science Engineer Intern (Jul 2024 – Dec 2024)
- Built and owned the MLOps pipeline for a clinical patient entity-extraction model serving multiple healthcare clients, raising accuracy from 72% to 94% on an internal held-out set via a human-in-the-loop retraining loop.
- Orchestrated fault-tolerant training and serving workflows on Temporal and SkyPilot across RunPod and Hugging Face Endpoints, standardizing deploys across models.
- Benchmarked open Vision-Language Models (incl. Gemma 3) with a reproducible ClearML test suite, surfacing a Flash-Attention/SDPA correctness issue in the serving path.
- Cut model cold-start latency 77% by pre-packaging weights and tokenizer into the runtime image and warming the serving process.
- Cut model training time from 90 hours to 25 hours on >500GB datasets via targeted hyperparameter tuning, and eliminated OOM errors with a custom memory-efficient iterable dataloader.
- Re-engineered single-node Python ETL into distributed PySpark jobs over FHIR resources for multiple clients, cutting data-loading time ~80% and unblocking training on 500GB+ datasets.

Machine Learning Intern · Banach Technologies
- Engineered and optimized high-frequency trading strategies, reducing data-processing latency through targeted performance tuning.
- Built and deployed ML models from scratch against live market APIs to execute hedging strategies, backed by a comprehensive unittest suite for core trading libraries.
Software / ML Intern · Alemeno
- Built a data-preprocessing pipeline for semantic-segmentation models over large-scale GIS raster data, and implemented distributed computer-vision algorithms (Douglas–Peucker, Jarvis March).
- Deployed scalable Django apps on AWS with an end-to-end CI/CD pipeline, and hardened a high-performance raster-processing app through refactoring and unit tests.
Data Analyst · Bewgle
- Applied NLP techniques to proprietary Amazon-review datasets to deliver product-trend insights and predictive models; automated preprocessing in Python/Bash, cutting data redundancy by 90%.
Projects
A zero-dependency NumPy, written from scratch in pure Rust — same internals as the real thing (flat buffer + shape + strides). Reimplements broadcasting, axis reductions, and matmul from first principles, then benchmarks a cache-friendly
ikj loop order against BLAS-backed NumPy. Spec-driven with ~30 milestone tests.A terminal player that browses YouTube Music and your local library side by side, plays audio through
mpv over its JSON IPC socket, and scrobbles to Last.fm via cmusfm. Vim-style keys, live search, play history, and pixelated album art rendered straight in the terminal.Core ML/DL models — backpropagation, CNNs, transformers — implemented from first principles in pure PyTorch, without high-level abstractions.
Scores a resume against a hand-written hiring rubric, then matches it against a pasted job description with an open-weights NLI model — entirely in the browser, no upload, no backend.
A CNN reaching 98.4% accuracy on medical waste classification, shipped as an interactive TensorFlow.js web app. Findings published in IEEE Xplore.
