Shefali Saini

Hi, I'm Shefali 👋

I'm a software engineer with over four years of experience at Amazon, where I worked across cloud infrastructure, platform modernization, and machine learning. I thrive at the intersection of building reliable distributed systems and leveraging data-driven automation to solve complex operational challenges.

Currently pursuing my Master's in Computer Software Engineering at San Jose State University with a perfect 4.0 GPA, I'm passionate about expanding my expertise in enterprise software architecture and emerging AI technologies.

Experience

Where I've made an impact

4+ years of building, scaling, and modernizing systems at one of the world's largest tech companies.

Software Engineer
Amazon
Aug 2021 – Aug 2025
Hyderabad, India
  • Expanded HEX MAWS services to a new AWS region (ZAZ), provisioning core infrastructure — Orca workflow, Apollo, ASGs, ALBs/NLBs, VPCs, subnets, security groups, and CloudWatch — for new teams.
  • Modernized platform by designing Java-based APIs, eliminating 45+ infrastructure risks per service (90K+ total), replacing legacy components, and transferring ownership to service teams.
  • Drove a migration campaign for 1,500+ services to adopt JDK 17, automating code reviews and actively supporting teams through successful migration.
  • Built Python ML models (Pandas, NumPy, scikit-learn, TensorFlow) to forecast traffic peaks; integrated with a Java backend workflow for automated EC2 scaling.
  • Automated alert pipelines (CloudWatch → SQS → Slack) to enhance operational visibility and reduce MTTR.
  • Onboarded customer tickets to GenAI TicketSummarizer, generating real-time summaries to improve efficiency.
  • Implemented Security Event Logging with 1-year retention using IAM and CI/CD for secure, auditable service logs.
  • Collaborated cross-functionally to debug and resolve Sev-1 Linux networking incidents in distributed systems.
Software Engineer Intern
Amazon
Jan 2021 – Jul 2021
Hyderabad, India
  • Launched "Sync Data," an internal automation tool built with Java, JavaScript, and DynamoDB; tested with JUnit and Mockito, adopted by 2,000+ teams to streamline data workflows.
  • Developed Bash scripts to automate infrastructure transfers and ownership validation for hostclasses.
  • Built a Tampermonkey script using JavaScript, HTML/CSS, and DOM manipulation to inject custom UI, automating repetitive tasks and boosting developer productivity by 70%.
Mentee – Campus Mentorship Series
Amazon
Jan 2020 – Jun 2020
Delhi, India
  • Built an end-to-end Python ML pipeline to ingest real-time Twitter data, apply NLP techniques (tokenization, TF-IDF, feature engineering), and evaluate customer sentiment.
  • Preprocessed 50K+ records with deduplication and feature engineering; built a React dashboard with FastAPI backend for real-time ML predictions.

Projects

Things I've built

Personal projects that push boundaries in AI, cloud, and data engineering.

🧴
Lumen – AI Powered Skincare Assistant
AI-powered mobile app with a serverless AWS backend (Lambda, API Gateway, S3, DynamoDB). Integrated ML and LLM pipelines (GPT-4o, Claude 3.5, RAG with Pinecone + Titan embeddings) with secure JWT-auth APIs, privacy-first data handling, and CloudWatch observability.
