FinOps & Adaptive Model Routing: Engineered an Intelligent Semantic Router that dynamically selects between SOTA models (Vertex AI/Gemini) and ultra-fast free-tier models (Groq/Llama-3) based on prompt complexity and real-time tenant budgets, slashing LLM compute costs. Distributed Resilience (SRE): Implemented enterprise stability patterns including Redis-backed Distributed Circuit Breakers to prevent cascading failures during AI vendor outages, and the AsyncSingleFlight pattern to eliminate cache stampedes in high-concurrency environments. (SOC2 Presidio for PII scrubbing. Application-Level Encryption (ALE) for all sensitive data at (Nested Loop): a continuous feedback architecture that Human-in-the-Loop (HITL) corrections, vectorizes them via pgvector, and injects them as Few-Shot examples. The system learns from user's corrections in real-time

Founded and led the development of digital educational products serving thousands of students, managing the complete SDLC from conception to deployment. Designed complex technical curricula and produced highly engineered educational content. Implemented data analytics dashboards to monitor student retention KPIs and optimize the sales funnel (Conversion Rate Optimization). Developed RPA scripts to automate content distribution, social media marketing, and community management, significantly reducing operational workload. Successfully scaled digital products on global platforms like Udemy, managing technical support and continuous updates based on user feedback.
