Confidential

Energy

Confidential Energy Registry Architecture

Lead architect on a regulated energy-sector certificate registry. Designed and built the replacement for a managed SaaS ledger platform with a client-owned PostgreSQL system. Five database-owned write functions hold the entire authoritative mutation surface. Append-only canonical ledger with a blockchain-style UTXO model and double-entry credit/debit postings, validated by a comprehensive integration test suite against real PostgreSQL.

Authoritative ledger surface: 5 stored functions covering the entire authoritative write surface
Integration test coverage: 100+ integration tests across 8 suites, all against real PostgreSQL

Software & Cloud Consulting

Peter T Conti Consulting Platform

The consulting practice's own site, built as the reference architecture for what the practice sells. Same Next.js + Payload + Postgres + ECS Fargate + Terraform stack as the anchor engagement. STS-only IAM, no long-lived credentials anywhere. Cost-tuned to run for a small fraction of the naive default AWS footprint, with full editorial workflow operated as code.

Stack: Next.js + Payload + AWS ECS + AWS Lambda + RDS Postgres
Infrastructure as code: Full AWS footprint Terraform-managed in modules; CI-only apply
