TrendDev – AI-powered job market analytics platform
- Architected a multi-service AWS serverless platform (20+ Lambdas, 5 API Gateways, Cognito auth, 10+ DynamoDB tables + Neon / Postgres) powering daily ingestion and analytics of tech job postings.
- Built an event - driven ingestion pipeline with Lambda + EventBridge + S3 + DynamoDB that processes thousands of postings/ day, normalizes skills(~7k unique technologies), and generates trend + salary analytics in near - real time.
- Implemented AI resume insights using Bedrock Nova + custom normalizers to produce role-fit scores, salary anchors, and skill ROI; supports multi- resume management, presigned uploads, and async processing.
- Designed and shipped a React/TypeScript/Vite dashboard with reusable component architecture, filtering/search across 500 + high signal technologies, responsive layouts, and Vitest unit coverage for critical UI + services.
- Achieved 95-100 Lighthouse performance scores across key routes despite data-heavy visualizations.
LegisTrack – Legislative tracking app
- Built a Next.js 15 + Prisma/Postgres platform that ingests and tracks U.S. bills + executive orders, exposing searchable, categorized legislative timelines
- Designed a normalized relational schema (bills, actions, sponsors, votes, companion bills, categories) and optimized indexes / queries for fast filtering on large datasets.
- Implemented automated ingestion + summarization workflows (Inngest → AWS Lambda migration) with retries/DLQ patterns and strict rate - limit handling.
- Integrated multi-provider LLM summarization (Claude, OpenRouter, OpenAI) with caching + model adapters, producing plain - English summaries at sub - cent cost per bill.
