Developer Experience Engineer

Built developer tooling framework with 19 MCP tools, structured workflows, and quality gates for AI-assisted development. Two-minute setup, zero codebase modifications.

Designed persistent cross-session memory so developer discoveries compound instead of resetting. Learnings indexed by keyword, recallable by any future session.

2,600+ tests with automated verification on every change. In beta across 5 coding platforms (Claude Code, VS Code, Windsurf, Aider, OpenCode). Engineers adopt it because it solves real problems.

AI-Assisted Development: Built 5-agent AI system reducing endpoint migrations from hours to <10 minutes. Engineers stopped treating migrations as a time sink and started treating them as a 10-minute task.

Migration Velocity: Enabled 289 endpoint migrations through AI tooling. 90% error reduction in schema mapping (weeks to hours).

Documentation-as-Code: Architected Truth Source documentation system that AI agents can consume. Agents reason from structured facts — schemas, ASTs, and test fixtures. Docs stay current because they're the source of truth for both humans and agents.

Observability Platform: Built real-time debugging system (Redis/Xdebug/BPF) reducing MTTR by 95%. Diagnosed Redis pooling issue achieving 95% DNS resolution and 97-98% OTP auth improvement.

Support Automation: Reduced L1/L2 support overhead from 25% to <5%, returning engineering time to feature work. Engineers actually thank me for these tools.

Cost-Efficient Monitoring: Achieved 62.5% DataDog cost reduction ($12K→$4.5K/month) while improving observability coverage. Better DevEx and lower costs.

Load Testing Pioneer: Led first load test in company history—5 sessions, zero system failures, 85-90% confidence for peak traffic.

Led teams processing $2B+ in transactions while scaling platform architecture 100x over four years, handling 50% month-over-month order volume spikes.

Pioneered GPT-3 implementation (2022, pre-ChatGPT) automating support workflows and saving ~2 hours/week/employee with NPS of 57—one of earliest enterprise GPT deployments.

Single-handedly led and delivered Instacart integration—company's flagship partnership initiative—owning architectural design, cross-team coordination, and executive visibility end-to-end.

Led the Shopify migration. Built the initial prototype, got buy-in from eng and ops, and saw it through to production.

Built a test data framework that worked across all environments, cutting CI/CD time by 3x.

Transitioned proof-of-concept customer support platform (Zendesk dashboard app) into production-grade React application serving 12-person operations team.

Platform Benchmark: Built platform recognized internally as the benchmark for Testing, Stability, Documentation, Innovation. Other teams measured against ours.

Reusable Tooling: Self-initiated DR-tolerant Azure Service Bus SDK now deployed across all compatible microservices company-wide.

Performance Baseline: In first 90 days, refactored critical paths boosting performance 87%. Set up regression testing so those gains held — future changes couldn't silently undo them.

Team Enablement: Built and documented CI/CD patterns that survived team turnover. New engineers deployed confidently in their first week because the system was that clear.

Rescued failing insurance platform 6 months behind schedule by restructuring architecture and coordinating 6-8 remote developers—delivered on-time with zero regulatory compliance issues.

Delivered real-time quoting engine handling complex state-specific regulations for all 50 states, processing quotes in under 2 seconds across 200+ rule variations.

Kept the client in the loop with weekly demos. The team was remote and under pressure, but we shipped on time every week.

Designed distributed architecture spanning AWS (US) and Aliyun (China), solving Great Firewall latency so cross-border purchases actually worked.

Architected unified logistics engine integrating 8+ international providers, automating bonded/free-trade import logic across 3 countries.

Implemented multi-currency payment system connecting 19+ payment gateways including ICBC (world's second-largest bank), directly enabling international transaction volume.

Won 2nd place at international technology competition in China; achieved compliance with public company (LifeVantage LFVN - NASDAQ) regulatory requirements.

Built and mentored distributed engineering team of 3+ developers post-MVP, instituting Agile/DevOps practices that scaled with the business.
