Projects
Domain Sales & Monetization Platform(current)
- Led backend and platform engineering for a serverless domain sales and monetisation ecosystem spanning 40+ repositories and supporting domain search, availability, pricing, landing pages, checkout, billing, and registry integrations.
- Designed reliable event-driven transaction workflows using AWS Lambda, API Gateway, EventBridge, SQS/DLQ, DynamoDB, PostgreSQL, and Redis, applying idempotency, retries, failure recovery, and observability practices.
- Consolidated billing and subscription capabilities behind an internal Recurly integration, covering checkout, add-ons, and entitlement lifecycle management.
- Authored architecture decision records and drove cross-service decisions across infrastructure, security, billing, domain boundaries, and event-driven processing.
- Designed and introduced a structured AI-assisted SDLC, initially implemented with GitHub Copilot and later re-engineered to Claude Code, using explicit task context, persistent workflow state (`status.yaml`), phased discovery, planning, implementation, testing, and review, test evidence, and mandatory human approval.
- Improved production diagnostics through structured logging, metrics, tracing, and failure analysis.
