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. https://media.petertconti.com/media/confidential-client-project-aws-topology-2048x1038.webp Confidential Client Project - Production AWS toplogy mermaid Diagram https://media.petertconti.com/media/01-mutation-surface-v2-2048x1910.webp Authoritative mutation surface for the certificate registry: every write flows through five SECURITY DEFINER PostgreSQL functions; EXECUTE is REVOKEd from PUBLIC, anon, and authenticated; the service role is granted EXECUTE on those five functions only. Invariants enforced via database-level CHECK and UNIQUE constraints plus commit-time triggers. Canonical tables are append-only. https://media.petertconti.com/media/02-utxo-block-lineage-v2-2048x902.webp UTXO certificate block lineage worked example: mint 100 units to account A, then transfer 30 units from A to B. The transfer consumes parent block 1 and produces two child blocks (block 2 in B with 30 units, block 3 in A with 70 units); the parent-to-child link is recorded in consumed_inputs. Triggers enforce: child volumes sum to parent volume, child ranges are contiguous and non-overlapping, consumed parent never queries as unspent. https://media.petertconti.com/media/03-double-entry-postings-2048x1494.webp Double-entry posting and commit-time validation: every mutation function writes paired credit and debit rows on credits_debits that sum to zero per (transaction_id, asset). A deferred constraint trigger fires at commit, computes SUM(volume) per (txn, asset), and either passes (transaction commits) or raises POSTING_IMBALANCE (transaction rolls back). https://media.petertconti.com/media/confidential-client-project-security-compliance-analysis-2048x435.webp Confidential Client Project - Security & Compliance Analysis Diagram https://media.petertconti.com/media/04-deterministic-locking-2048x2777.webp Deterministic locking eliminates cross-transaction deadlocks: parallel transfers A→B and B→A both call the lock helper which sorts UUIDs to identical [A, B] order; T1 acquires the locks first, T2 queues; T1 commits and releases; T2 then runs and either commits or rolls back with INSUFFICIENT_TOTAL_BALANCE. Concurrency suite asserts: two parallel 80-unit transfers from a 100-unit source serialize correctly with no phantom double-spend. https://media.petertconti.com/media/05-reconciliation-checks-v2-2048x1611.webp Read-only reconciliation function as a first-class production health check, fired on a 5-minute CloudWatch schedule and via operations CLI. Runs four orthogonal drift checks (spent-input invariant, balance drift, asset conservation, posting balance) and emits a JSON report. Lock-free; passing run posts a CloudWatch metric, failing run fires an SNS alarm to on-call. https://media.petertconti.com/media/confidential-client-project-cicd-access-pattern-2048x654.webp Confidential Client Project - CICD Access Pattern Mermaid Diagram https://petertconti.com/case-studies/petertconti-consulting-platform https://media.petertconti.com/media/conti-og-2048x2048.webp Peter T Conti Consulting Platform The consulting practice's own site, built as the reference architecture for what the practice sells.

Sales happened through staff, phone, email, showroom conversations, FileMaker, and disconnected vendor tools. I built the first transactional commerce and operations platform inside the client’s own AWS Organization. It now supports millions in annual revenue, including six-figure monthly commerce volume; migrated 28,062 invoices and more than 20 years of operating history without loss or duplicate invoice numbers; and cut over with zero downtime. The custom quote, deposit, ACH, wire, check, signature, fulfillment, acquisition-feed, and staff workflows are now operated through a Fractional CTO retainer. https://media.petertconti.com/media/fines-og-2048x1560.webp Fine's Gallery Logo https://media.petertconti.com/media/fines-sales-dashboard-original-2048x1044.webp Fines Gallery Custom Sales Dashboard / Control Center https://media.petertconti.com/media/fines-analytics-2048x1254.webp Fine's Gallery User Acquisition Analytics https://media.petertconti.com/media/01-aws-topology-4-2048x1602.webp Sovereign client-owned AWS Organization topology: WAFv2 + CloudFront edge, ECS Fargate application tier, RDS PostgreSQL + S3 data tier, SQS + Lambda async backbone with EventBridge / MediaConvert / outbox publisher, KMS / IAM / Secrets Manager security, and first-party integrations with Stripe / DocuSign / Klaviyo / GMC / GA4 / Pinterest / CallRail. https://media.petertconti.com/media/03-system-context-4-2048x639.webp System context for the Fine's Gallery commerce platform: customers and staff interact with the storefront and admin surface; the backend composes order state, invoicing, payment ledger, and the async backbone, and integrates with Stripe / DocuSign / Klaviyo / GMC / GA4 / Pinterest / CallRail. https://media.petertconti.com/media/fines-order-state-machine-2048x879.webp Fine's Gallery Order State Machine https://media.petertconti.com/media/02-async-backbone-4-2048x2153.webp Async backbone: producers (web requests, EventBridge Scheduler, third-party webhooks) publish to 5 SQS queues; 5 Lambda workers consume them with typed task contracts; each queue has a DLQ wired into CloudWatch alarms; an outbox publisher republishes any operation stuck in pending or unknown delivery state. https://media.petertconti.com/media/fines-gallery-order-to-cash-diagram-2048x625.webp Fine's Gallery Order to Cash Mermaid Diagram https://petertconti.com/blog/sovereign-ai-agent https://media.petertconti.com/media/sovereign-ai-agent-hero-2048x1269.webp The Sovereign AI Agent: Production Ops in an Account You Own Deploy AI agents that manage real AWS infrastructure.
