AI Product Developer Vasundhara Infotech
Owned the LLM content platform for Sensor Tower across five B2B SaaS products in the App Store and Google Play ecosystem. Designed a provider-agnostic LLM layer supporting Claude, Gemini, Groq, and OpenAI-compatible endpoints with structured JSON-schema output, streaming, and automatic retry and backoff handling.
Created an evaluation harness to compare prompt variants against baselines using held-out cases, binary pass/fail assertions, and aggregated scoring. Built a multi-stage self-critiquing generation pipeline using planning, drafting, editing, reviewing, and revision prompts grounded in brand knowledge and post history.
Developed a scraping and corpus-cleaning pipeline for 275 articles, extracting category-specific writing-style features and combining deterministic metrics with LLM-as-judge evaluation. Shipped publishing integrations for nine social platforms with OAuth 2.0, token refresh, media handling, and character-limit support.
Implemented Fernet-backed encryption at rest for OAuth tokens and API keys, including migration support and backend test coverage. Also produced SEO articles, generative brand media, and Postman API documentation for RefundSensor authentication, refund events, transactions, analytics, and Apple App Store Server Notification webhooks.
