Saswat Samal. Software engineer in Bengaluru, India. I build AI agents, backends and cloud infrastructure that hold up in production. Open to collaborations. Now at Aina, building the AI voice agent. Open source: Lima, Jaeger, NVIDIA Dynamo.

LinkedIn Email Blog X Résumé

01 Impact at Aina

At Aina ($5.5M seed) we build hardware for AI agents. Dune, a context-aware 3-key Mac keypad, hit #1 on Product Hunt. Aina Ring, a ring with a small screen that shows the one decision your agents need from you, launched in San Francisco and Bangalore in November 2026. I built the ring's voice agent and moved our backend to production AWS.

1,500x faster query: 30 s to 20 ms, it was 23% of production DB time. 2.4 s removed from every voice command. About 95% of prompt tokens hit the prompt cache. 20+ tools the voice agent calls, plus MCP.
What I built at Aina
  • Built the AI voice agent for Aina Ring: LLM tool calling (Claude, OpenAI) over 20+ tools, plus MCP connectors (Notion, Slack, Linear) for home control, Spotify, calendars and notes
  • Gave it long-term memory with RAG: local embeddings and pgvector (HNSW) search, with prompt caching on ~95% of prompt tokens
  • Migrated the whole backend to production AWS: RDS Postgres, 9 ECS services, CodeBuild + ECR CI/CD, EventBridge, SQS/SNS and a private VPC
  • Rebuilt the analytics pipeline: API Gateway → Kinesis → Firehose → S3 (Parquet) → Glue → Athena, with DMS change data capture from Postgres
  • Fixed a WhatsApp outage that hit at 6 users (thread-pool exhaustion); it now handles 100+ sessions
  • Shipped a Home Assistant plugin with signed self-updates and auto-rollback, so voice can control any device
02 Journey 2020: IIIT Bhubaneswar, B.Tech in Computer Science (2020 to 2024). 2023: UniStack, SDE Intern. 2024: Badho, Full-Stack Developer. Now: Aina, Software Engineer.
Earlier roles

Badho · Full-Stack Developer · Oct 2024 – Nov 2025

  • Designed a workflow orchestration engine on Temporal (Node.js, PostgreSQL) with a JSON DSL, auto-versioning and multiple queues, built for millions of workflows. Deployments went from days to minutes

  • Built search, confirmation, status, tracking and cancellation for the ONDC logistics buyer app, cutting task completion times by 20%
03 Open source Lima #5675: shell opens the matching guest directory for remapped mounts Lima #5602: keeps the progress line intact while host agent logs stream in Lima #5771: keeps port 22 privileged so non-root users can't fake sshd Jaeger #9930: retries failed Cassandra name inserts NVIDIA Dynamo #16127: deprecates the unused --mm-prompt-template flag cognee #5674: returns 409 instead of 500 for a duplicate role name
