    Software Engineer / Technical Lead · Tenxer Labs

    LiveBench - Cloud platform for live remote evaluation of real ICs and hardware.

    • Lead a team of 6 engineers across backend, middleware, frontend, and infrastructure (since Mar 2025); drive architectural decisions, code reviews, and sprint planning with the Engineering Manager.
    • Architected real-time multi-user connectivity to physical hardware labs using Kafka, gRPC, WebSockets, and Redis-based locking, streaming live instrument data from 200+ labs to browsers worldwide.
    • Engineered live lab video streaming via GStreamer and Janus (WebRTC) with TURN/STUN firewall traversal, unblocking enterprise customers behind strict corporate networks.
    • Reduced cloud infrastructure costs by up to 70%, owning AWS and Cloudflare end-to-end: OpenTofu IaC, Jenkins CI/CD pipelines (dev/UAT/prod), and a Proxmox on-premises server integrated as a private AWS-style region via OpenVPN.
    • Cut page load times from 15s to 3s (80% faster) across the React frontend.
    • Built the ingestion pipeline for an agentic RAG Knowledge Assistant over IC datasheets: multimodal extraction (Gemini 2.0), table-aware chunking, and batched embedding generation.
    • Developed a vendor-agnostic oscilloscope library unifying waveform capture across 4 major instrument vendors (Keysight, Tektronix, Rigol, Scientific Instruments); built backend services in Ruby on Rails and Node.js (Express) on PostgreSQL.
    • Made all repositories agentic-ready by authoring ADRs and architecture documentation as shared LLM context, enabling developers to use any AI coding assistant effectively across the codebase.
