- Designed and shipped autonomous AI agents in production on AWS Bedrock AgentCore (Claude) — including an internal autonomous "virtual employee" (OpenClaw in Lightsail) that maintains a live wiki of the entire codebase, reviews PRs and make cross repo changes. - Built an event-driven balance-confirmation platform — a multi-trigger AWS Lambda routing HTTP, Step Functions batch jobs, and an SES → EventBridge → SQS event pipeline with idempotent, per-recipient delivery tracking and async email workflows. - Built production fintech services end-to-end — architecture, code, and AWS infrastructure; four services built from scratch. - Led a zero-downtime authentication migration — moved the login flow from the ALB (which integrated with Cognito directly) to the frontend, with the ALB downgraded to validating UI-issued JWTs via the JWKS endpoint — with under a minute of downtime and zero user-visible change. - Architected for extensibility, scale, and security — design patterns that make new features one-file additions, PostgreSQL row-level multi-tenancy, and performance work (e.g. a 45k-row write cut from minutes to seconds, ~30×). Owned AWS infrastructure & CI/CD across the platform — Bedrock, ECS, Lambda, Step Functions, EventBridge, SQS, SES, Aurora, Cognito, WAF, VPC — with standardized pipelines and dependency-vulnerability scanning.

- Built the core backend for the company's first reconciliation product — the DB schema, business-logic engine, and async REST APIs, along with reporting and metrics. - Built a multi-provider email-ingestion service (IMAP / Office 365 / Gmail) with token-refresh authentication, containerized and exposed through a REST API. - Delivered features across several services — including a Node/TypeScript data service and an automated notification service — and implemented JWT-based authentication middleware. - Deployed and ran these services on AWS — containerized on ECS/ECR, plus Aurora PostgreSQL and a DocumentDB datastore — and set up CI/CD foundations with PR test-coverage and deployment workflows across repositories.
