    • Software Engineer - Backend Team Lead
      Aug 2025 - Present · 11 mos

      I lead the development and operations of backend systems across our products, focusing on architecture, scalability, and reliability. My work includes designing distributed backend services, evolving a Python FastAPI ecosystem, and ensuring AI-powered features (serverless infrastructure or API's) run reliably in production environments. I’m responsible for coordinating backend development and delivery across the team, including technical planning, code and design reviews, and cross-team collaboration with product, mobile, and DevOps. My work also includes API design, backend performance optimization, AWS infrastructure management (EC2, S3, SQS, container orchestration), observability with Datadog, and continuous improvements to deployment and release workflows. The backend systems I work on support several consumer-facing AI applications, including Banger AI, FaceAI, AI Dub, ChatIn, and VideoAI, enabling AI-driven media generation, video processing, and real-time user interactions at scale.
