02 · Experience

A career built across the full AI stack.

Applied modeling, data platforms, cloud delivery, and enterprise AI governance—developed through increasingly complex production environments.

Jan 2026 — Present Senior AI EngineerAmgen · Thousand Oaks, CA

Building ML infrastructure and reproducible evaluation workflows for protein-language-model and multi-omics use cases.

  • Build ML infrastructure and evaluation workflows for protein-language-model and multi-omics use cases within Amgen's generative-biology environment.
  • Benchmark AMPLIFY's 120M- and 350M-parameter checkpoints on protein sequences up to its published 2,048-residue context.
  • Track task metrics, model configurations, sequence-length test slices, and efficiency regressions in MLflow to make checkpoint comparisons reproducible.
  • Analyze task-quality and compute trade-offs between the 120M and 350M checkpoints by sequence-length slice; the published AMPLIFY 350M comparison reports 43× fewer parameters and 24–29× higher inference throughput than ESM2-15B, depending on sequence length.

  • Tuned PostgreSQL queries and added Redis caching where repeated analytics requests were slowing dashboards.
  • Supported containerized model delivery and CI/CD workflows for repeatable development and release processes.
  • Built Tableau and Matplotlib reports for KPI, pipeline, and model-review discussions with client teams.
Aug 2017 — Jul 2021 Associate Software EngineerDozee · Bengaluru, India

Developed physiological signal-processing, time-series modeling, and inference workflows for contactless patient monitoring.

  • Built ballistocardiography signal-processing pipelines that converted under-mattress micro-vibration data into cardiac and respiratory features; by June 2021, the Government of India reported that the broader Dozee platform had served 30,000+ patients across 4,000+ beds in 35 districts.
  • Developed reusable preprocessing and feature-extraction workflows with SciPy, Pandas, and NumPy for physiological time-series data.
  • Trained and evaluated 1D-CNN and LSTM models for respiratory events and physiological anomalies.
  • Compared model outputs with patient-level reference monitoring data and performed clinically relevant error analysis.
  • Added temporal trend features used by early-warning workflows for longitudinal physiological monitoring.
  • Packaged reusable feature extraction in Dockerized Flask services for low-latency inference.
