Lead reliability for blockchain platforms while building Ledger's self-hosted AI platform for developer productivity.
- Centralized MCP servers and model providers (AWS Bedrock, GitHub Copilot) behind LiteLLM as a single gateway.
- Cost and usage governance across teams through Langfuse and LiteLLM.
- Deployed 4 NVIDIA A10G GPU nodes on AWS Kubernetes served with vLLM: Mistral-7B for agents, Qwen3-8B for chat, Llama-Guard-3-8B for guardrails, BAAI/bge-m3 for embeddings.
- Deployed Coder as the execution environment for an internal AI agent: employees open Jira tickets from Slack, the agent spawns its own Coder workspaces and handles the task end to end, working across multiple repos in parallel.
- Migrated PostgreSQL to CloudNative-PG with GitOps; database observability via Percona Monitoring and Management (PMM), with dedicated Docker images for PMM and pgAdmin.
- Operate blockchain nodes: Bitcoin, Ethereum and more.
