Venture capital funds, private equity acquirers, and non-technical SaaS founders frequently search to hire a freelance technical due diligence auditor, codebase reviewer & hands-on fractional CTO programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and AI Systems Architect available via Upwork.

Core Technical Due Diligence & Hands-On Architecture Capabilities

  • M&A & Investor Codebase Audits: Evaluating architecture scalability, PostgreSQL schema integrity, security vulnerabilities (OWASP / secrets exposure), test coverage, open-source license compliance, and cloud unit economics.
  • AI Strategy & Architecture Feasibility Reviews: Separating genuine proprietary AI/RAG engineering from brittle prompt wrappers, and designing concrete roadmaps to improve accuracy while lowering inference costs.
  • Hands-On Fractional Principal Engineer / CTO Execution: Unlike advisory-only consultants, I write production Python, Go, TypeScript, and SQL code directly alongside your team to unblock critical path deliverables.
