  • I worked on the development of a chatbot assistant through multiple user stories, using FastAPI, Docker, GCP, and Vertex AI for the backend environment.
  • I worked on the implementation of video transcription pipelines, leveraging the YouTube Transcript API and Whisper, ensuring accurate and complete transcript extraction.
  • Designed and managed Google Cloud Platform (GCP) resources, including IAM roles and Vertex AI instances, following least privilege and cost optimization practices.
  • Integrated Firestore with FastAPI, enabling structured data storage and retrieval, optimized for LLM processing, and semantic search.
  • Applied prompt engineering techniques with Gemini Vertex AI, enabling the chatbot to generate intelligent, context-aware responses.
  • Deployed applications in Docker containers, maintaining service separation for scalability, reliability, and smooth CI/CD integration.
  • integrated Apify video scraping pipeline as a tool within the Langchain framework, enriching LLM-based applications with real-time, dynamic data.
  • Designed and implemented a unified ActionExecutor class to orchestrate tool execution with automatic retries, exponential backoff, and structured error handling.
  • Created a configurable tool registry (TOOL_CONFIG) to manage multi-service integrations (AI chat, prompt history, smart context, cultural notes), enabling extensible, and maintainable backend workflows.
  • Secured service-to-service communication with Google Cloud Run authentication tokens, ensuring reliable, authenticated requests across microservices.
  • Engineered a multi-LLM integration layer (OpenAI, Gemini, Cohere, DeepSeek) with provider fallback logic, conversational memory, and response caching.
  • Implemented rate limiting with SlowAPI and custom key-based policies to balance fairness across users.
  • Developed endpoints for autocomplete, follow-up question generation, smart context, and cultural notes, integrating Gemini for contextual analysis, and Imagen for AI-driven cultural illustrations.
  • collaborated on media processing pipelines with FFmpeg and OpenCV to extract video frames, enrich transcripts, and support multimodal AI analysis.
