Staff Engineer (Flagship)

Built multi-agent AI migration system with 5 specialized sub-agents, reducing endpoint migration time from hours to under 10 minutes—enabled 289 endpoint migrations at unprecedented velocity.

Reverse-engineered legacy compiled Acucobol systems without source access, producing 45+ migration specifications (1.75MB/50,000+ lines) through AI-assisted bytecode analysis with 99%+ query accuracy.

Orchestrated 34 parallel AI agents for migration validation framework, achieving 90% error reduction in schema mapping (validation suite, before/after comparison).

Designed Truth Source Architecture enabling AI agents to consume documentation and refactor code without hallucination—patterns now adopted organization-wide.

Built AI sprint intelligence system using historical transcripts as knowledge base—benchmarked against human estimates at ±1 story point (blind comparison, 6 sprints), achieving 2.5x throughput (story points over 6 sprints) and 13% sprint efficiency gain.

Designed AI governance framework—read-only agent accounts, DevOps approval workflows, failure-as-state design principles—after identifying blast radius from an unscoped agent action.

Flagship Integration: Single-handedly led and delivered Instacart integration, the company's highest-profile partnership initiative. Owned architectural design, cross-team coordination, and executive visibility end-to-end.

Zero-Tolerance Delivery: Selected as top performer to lead initiatives where failure wasn't an option: ERP integration, ECOM migrations, new business line launches.

Executive Trust: Became the engineer leadership called for critical initiatives. Complex projects, tight timelines, minimal surprises.

6-Month Turnaround: Diagnosed failing architecture in week one. Over-abstraction couldn't handle state-specific variations. Restructured to rules-engine approach, delivered 50-state compliance on deadline.

Zero Regulatory Defects: Real-time quoting engine handling insurance regulations for all 50 states. When compliance is non-negotiable, architecture must be right the first time.

Post-Mortem Discipline: Documented root cause analysis for client. The original architecture optimized for developer convenience over regulatory flexibility. Learning transferred to prevent repeat.

Team Building & Execution: Built Operations team from 0 (solo) to 9 engineers across 3 specialized squads (Operations backend, CS Support, API migration), then led all 3 teams (12 engineers total) through 10x COVID surge with zero scaling incidents.

Platform Stability: Built platform that became the internal reliability benchmark. When orders grew 50% MoM and competitors went down, we had uneventful days.

Performance Under Fire: In first 90 days, refactored critical paths boosting performance 87%. Established credibility that led to expanded scope and Principal promotion.

Uneventful Cutover: Led 289-endpoint migration at 96% production traffic. 99.99% uptime during 50% global traffic cutover. The goal isn't exciting deployments; it's boring ones.

Deployment Confidence: Led first load test in company history—5 sessions, zero system failures. Created culture where teams trust their releases because they've proven them.

Structural Capital Recovery: Delivered $336K+ annual savings under pressure while maintaining mission-critical reliability. Finance loved the numbers; engineering loved the stability.

Predictable Performance: Achieved 4x order processing (300→1,300/5min) through systematic optimization, not heroics. Sustainable velocity, not sprints.

Designed distributed architecture spanning AWS (US) and Aliyun (China), solving 'Great Firewall' latency and enabling seamless cross-border e-commerce.

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.

Led development of multi-channel sales automation achieving +1,700% YOY sales and -44% overhead reduction (shipping -44%, labor -17%) within 1 month of deployment.

Designed centralized inventory orchestration engine integrating Amazon, Overstock, NewEgg, and 6+ additional marketplaces into unified platform.

Managed team of 4 (3 developers + designer) developing MLM/Direct Sales management platforms from conception to production.

Developed core development tools and coding standards adopted across all company projects, establishing engineering consistency.
