Senior Backend Engineer (ex-Amazon) โ Java, distributed systems, and APIs at scale. Six years building ad-serving systems handling millions of devices, and the tooling that keeps large systems reliable.
| Project | What it does | Stack |
|---|---|---|
| AgentTrail | Flight recorder for AI agents: append-only event log of tool calls, errors, handoffs, file changes, token costs โ with dashboard and Claude Code hooks | Java 21, Spring Boot, PostgreSQL, React |
| IncidentVault | Shared incident knowledge for humans and AI: timelines, logs, root causes, fixes, runbooks โ searchable via REST and MCP | Java 21, Spring Boot, PostgreSQL, MCP, React |
| SchemaGuard | Catches breaking API changes before deployment: diffs OpenAPI specs, classifies 60+ breaking-change rules, gates PRs in CI | Python, GitHub Actions |
| APIReplay | Reproduces backend bugs without production access: record, sanitize, replay, and diff HTTP traffic | Python (stdlib-only) |
| ContextBridge | Structured handoffs between AI coding sessions: save and resume context across sessions | Python (stdlib-only) |
Also: a senior-bar engineering playbook (coding, review, testing, design, production practices) and a Java backend interview handbook with runnable code and an interactive study site.
- Ex-Amazon, SDE 2 โ backend for ad serving at massive scale (millions of devices, ~$100M revenue impact)
- Deep in distributed systems: consistent hashing, replication, consensus, event-driven architectures
- Currently preparing for backend engineering roles in AI platform, data, cloud, and security lanes
