About Me

I am an innovative and results‑driven data engineering and cloud solutions specialist with proven expertise in designing, implementing, and automating large‑scale data pipelines across hybrid cloud environments (AWS & Google Cloud). My work spans orchestrating secure, high‑volume data transfers, real‑time analytics, and predictive modeling for IoT and supply‑chain use cases. I thrive on deriving actionable insights from time‑series sensor data for risk assessment, anomaly detection, and forecasting.

Technical Skills

Key Projects & Achievements

Fully Automated Hybrid Cloud Data Pipeline

Designed and implemented an end‑to‑end pipeline to extract sensor data from TimescaleDB and transfer it to AWS S3 via Lambda, then to Google Cloud Storage, and finally ingest into BigQuery using Dataflow. Automated deployments using CI/CD ensured seamless updates while incremental loads were achieved by storing last‑timestamp checkpoints in S3.

IoT Temperature Excursion Risk Scoring

Developed a BigQuery and Cloud Function system to combine multiple tables and calculate risk scores for temperature excursions in pharmaceutical shipments. Implemented a real‑time risk scoring algorithm with configurable thresholds (15, 30, 60 minutes) to classify shipments into red, yellow, and green zones.

Predictive Analytics for Supply Chain Sensors

Built LSTM‑based models to forecast temperature excursions using 15‑minute interval sensor data. Experimented with ARIMA and CNN‑LSTM hybrid models to improve anomaly detection and reduce false negatives in sudden excursions.

FastAPI‑based Model Serving

Deployed trained Vertex AI models via FastAPI endpoints to receive live input temperature values and return predictive outputs for proactive shipment monitoring. This enabled real‑time decision‑making for supply chain stakeholders.

BigQuery Data Management APIs

Created serverless APIs with API‑key authentication to query BigQuery for shipment and sensor data by time windows and organization IDs. Enabled flexible querying (last 24 hours, last X hours) and automatic UTC timestamp handling for consistency across systems.
