Projects

AI Copilot

Open-Source AI Agent Runtime

Local-first AI agent runtime that compiles to a single Go binary and configures behaviors via versioned YAML configuration files instead of proprietary code.

Built: Architected a modular Go engine with policy-as-config execution chains. Integrated direct LLM client interfaces (llama.cpp, OpenAI, Anthropic) and Model Context Protocol (MCP/ACP) handlers natively in-process.
Result: Shipped 26+ open-source releases under Apache-2.0, enabling sub-100ms local tool execution and reducing runtime footprint to a single 30MB binary.

MCP Server & Document SaaS

Multi-tenant SaaS platform built on an open-source AI agent runtime, adding document storage, vector search (RAG), and Model Context Protocol access.

Built: Designed a multi-tenant RAG service with document parsing and embeddings. Built the SaaS management layer, including RBAC, member invitation flows, audit logs, and Stripe billing integration.
Result: Delivered a production-ready SaaS control plane that indexes document collections and exposes them via MCP to external agents with sub-200ms vector search latency.

Direktiv — Kubernetes-Native Engine

Event bus optimizations and observability updates for a Kubernetes-native serverless workflow engine.

Built: Re-architected the internal event routing, decoupled long-running database queries, and implemented a structured slog logging system in Go. Built open-source observability pipelines using OpenTelemetry, Fluent Bit, and Prometheus.
Result: Increased event processing throughput by 10x and reduced workflow execution latency on critical routing paths to under 5ms.

Multi-Tenant ERPNext Platform — Operator & Control Panel

Kubernetes-native provisioning platform and control plane to deploy and operate isolated ERPNext instances for B2B tenants.

Built: Developed a custom Kubernetes operator in Go to manage the lifecycle of ERPNext containers, databases, and assets. Built a web-based administration dashboard for day-2 operations (database migrations, backups, resource scaling) and automated provisioning with Terraform and Ansible.
Result: Automated tenant provisioning from several hours to under 5 minutes, allowing a single operator to manage a fleet of 50+ isolated ERPNext instances.
