What I'm looking for

I’m looking to lead backend and platform work on event-driven microservices, taking architectural ownership, performance optimization, and production operations from design to delivery.

I’m a tech lead shipping production microservices in Go and Vue 3 + TypeScript, with strong ownership of architecture and reliability. I built and own a Redis-only Go call-routing service that handles 10,000+ calls/sec with P99 under 50ms.

I design event-driven systems end-to-end—Kafka event bus contracts, Redis keys and topics shared via JSON Schema, and multi-tenant controls with route-level RBAC. I’ve also engineered the telephony pipeline around Kamailio + FreeSWITCH fleets and split persistence across PostgreSQL config and TimescaleDB time-series.

On the product side, I deliver operational tooling like Vue 3 admin dashboards with SSE live call state and a Vue Flow editor with custom IVR nodes. I bring a performance-first, measurable mindset from infrastructure improvements to observability and cost reduction.

Owned AWS infrastructure across Amplify, serverless ECS, EC2, RDS, ECR, and MQTT brokers, improving production reliability by 40%. Optimized MySQL/RDS (CPU 70%→20%, 3x query performance), rebuilt Datadog observability (monitoring spend $8K→$1K/month), and shipped real-time optical-fiber monitoring (MTTD +52%, downtime -31%).

Built TalkerCRM, a multi-tenant conversational AI platform with per-business isolation, RBAC, and per-message token tracking, using LangGraph routing across seven specialist nodes. Optimized ETL on a 600+ GB PostgreSQL database (batch time -45%, storage -30%) and reduced LLM token usage 40%+ and per-turn cost a further 60%+ via Gemini context caching.
