AI video post-production for short-form creators and enterprise teams.

• First enterprise deal

  Closed the platform's first enterprise deal by shipping a production-ready video pipeline to Seekho, converting it into a paying client and validating the product commercially.

• Two-pass STT architecture

  Reduced STT token usage by 89% with a two-pass architecture, cutting pipeline latency while preserving timestamp accuracy across multilingual audio.

• Async B-roll pipeline

  Architected a five-stage async B-roll video pipeline (FastAPI, Docker) for parallel multimodal asset generation across sticker, text, poster and video overlays, backed by an AWS SQS worker with S3 offloading and containerized Lambdas at 99.9% uptime.

• Retrieval for AI workflows

  Built RAG retrieval pipelines (embeddings, vector search) that ground LLM generation in retrieved context, integrated with the FastAPI services and PostgreSQL data layer.

Production voice AI agents.

• Post-call analysis cost ~77% lower

  Took per-call LLM analysis from $0.009 to $0.002 by removing duplicated prompt payloads, adding Gemini prefix/context caching and fixing pricing bugs across cached-token and audio-token tiers.

• Sentence-level TTS cache

  Designed a response-caching layer (Redis/ElastiCache + S3, msgpack-serialized) that transparently wraps the TTS provider and eliminates redundant paid synthesis, rolled out platform-wide with per-agent toggles and cache-hit observability.

• RAG for voice agents

  Built retrieval into production voice agents, using embeddings and vector search to ground LLM responses in retrieved knowledge.

• Context-aware suggestions

  Integrated the OpenAI Chat API for context-aware suggestions, raising form completion by 35%.

• Clearance Resume

  Developed backend systems and REST APIs for an AI-powered resume parser and builder, growing user sign-ups by 40%.
