ML/AI Engineer

• Built Ask NuMaa, the AI pregnancy assistant on numaa.ai: a chat interface with multi-turn conversation history, saved chats, and a user Memory feature, backed by FastAPI and NestJS services with an LLM layer on OpenRouter.
• Built the RAG pipeline behind it with text embeddings and pgvector semantic search over curated clinical guidelines so answers are grounded in trusted medical content rather than model memory.
• Implemented question routing with a zero-shot classifier and explicit state machine: off-topic requests are declined, ambiguous ones get a clarifying question, in-scope ones go to the right handler, and users can be handed off to a real doctor when needed.
• Built the Memory and Add Context features on a MongoDB-backed user context store (profile, pregnancy stage, preferences, prior chats) with embedding-based lookup so the assistant personalizes responses across sessions.
• Built the Mom to Mom community feature (posts, replies, moderation) and the AI companion chat that runs alongside it, sharing the same auth, user profile, and context store.
• Integrated ElevenLabs for streaming speech-to-text and text-to-speech so users can talk to the assistant instead of typing.
• Containerized every service with Docker and deployed to AWS behind a reverse proxy; set up CI/CD so services build, test, and scale independently.

• Built a bidding marketplace where EHS (environmental, health, and safety) professionals bid on client job postings; owned the feature work across the Angular 19 frontend and Node/Express REST backend.
• Designed the PostgreSQL schema for users, job postings, and bids, and added indexes for the listing and search queries that showed up as slow in early testing.
• Implemented JWT-based authentication with role-level access control for client and professional accounts, plus request validation on all write endpoints.
• Built the listing, bidding, and dashboard views in Angular 19 + TailwindCSS and wrote integration tests for the core API flows before handing the codebase off.

• Developed and maintained C++ modules in a financial data pipeline that feed REST microservices consumed by client-facing dashboards; optimization work on the data processing paths improved throughput by 25% and cut end-to-end delivery latency.
• Built and maintained AngularJS 1.x UI components for client-facing financial products, working from JIRA tickets through code review and production release.
• Debugged production and runtime issues in UNIX environments with gdb and log analysis; managed source through Perforce with JIRA sprint workflows on a 15-engineer team.
• Migrated the frontend test suite from Protractor to Cypress and then to Playwright, cutting execution time by 35% and reducing flaky tests by 20%, which got CI feedback down to same-day.
