I build cloud data systems, ML-enabled workflows, and backend platforms that turn messy business data into reliable products.

A place for technical essays, implementation notes, career reflections, and lessons learned while building AI systems, data pipelines, backend products, and a career around them.
If a career fair ends without an interview, was it still worth attending? Ten lessons from San Jose on positioning, market signals, communication, networking, and growth.

Read postSelected work from my AI, data engineering, analytics, backend, and systems resumes. The common thread: take a hard data problem, design the workflow around trust and scale, and make the result usable.
Static GitHub Pages tool that extracts speech from uploaded video, uses a user-provided Groq key for transcription and Orpheus voice generation, then renders a downloadable video locally.
Built an AI-powered resume tailoring pipeline that reads a resume plus job description, rewrites only the relevant evidence-backed bullets, and regenerates a polished PDF from the original LaTeX template.
Built a real-time assistive AI system combining Faster R-CNN object detection, BLIP-2 image captioning, OCR, and NLP-driven auditory feedback.
Designed a clinician-facing gastric cancer screening pipeline using ResNet-50 and Grad-CAM saliency maps for interpretable real-time predictions.
Automated clinical-trial ingestion, validation, deduplication, and fuzzy matching workflows for structured healthcare data using Python, SQL, and AWS services.
Architected a distributed OLAP-style query engine using Java and Apache Pekko typed actors for multi-cluster graph analytics workloads.
Engineered a three-class dermoscopy classifier using EfficientNet, Grad-CAM overlays, SMOTE, class weighting, and augmentation for lesion interpretation.
Optimized PostgreSQL B-Tree index prefetching and scan behavior for OLAP benchmark queries using C, Docker, GDB, and JOB/IMDB workloads.
Migrated RDF/SPARQL graph logic to Neo4j for customer microsegmentation, KOL identification, and graph-based feature analysis.
Used PySpark, AWS, EDA, statistical analysis, and Tableau to identify outliers and propose top diversity-rich clinical sites for trial planning.
Led a Flask-based predictive analytics app with preprocessing and feature engineering to forecast flight price fluctuations.
Built and evaluated a logistic regression model for fraudulent transaction detection with data cleaning and feature engineering.
Converted video to images, isolated human objects with TensorFlow, measured distances, and highlighted social distancing violations.
Developed Angular and Flask API flows for Excel uploads, using SQL and Python microservices to improve data-heavy planner workflows.
Deployed a Java-based AWS REST API to generate keyword weightings from submitted text and tested reliability with Postman on 500+ samples.
Led a real-time geolocation system with Firebase portals for drivers and traffic police, automating proximity alerts for emergency response.
