Highlights

  • ixo · Platform

    Multi-cloud Terraform platform

    An open-source, config-driven Terraform platform across Vultr, AWS and GCP. A team adds one .tfvars file and gets its own environment, so anyone with code-level skills can bring up their own ixo-like stack.

  • BMTX · Backend

    Identity verification platform

    A partner-facing KYC/IDV platform built from scratch, as a gRPC public gateway plus domain engine, a Spring Batch pipeline for PGP-encrypted cohort files, and a decision layer over Socure.

  • opcode · AI platform

    Guardrails for AI agents

    Platform engineering for AI agents. I took opcode, an open-source desktop app for Claude Code, and rewrote large parts of it into a manager/worker system with model caps, budgets, file locks, an owner inbox and rule files.
