I’m a CTO / Director-level engineering leader with 16 years in software and 10+ years in leadership across Amazon, Worldline, Synopsys, and a fast-moving startup environment. I help founders and exec teams ship scalable platforms, fix reliability/performance bottlenecks, and build engineering organizations that execute without chaos. How I can help you? I bridge the gap between deep technical execution and VP-level business strategy. Whether you need to re-architect a legacy system, integrate AI into your workflow, or scale your engineering culture, I provide the framework to do it predictably and at scale. * Exec/CTO advisory: org design, operating cadence, hiring plan, execution rhythm, roadmap alignment with business goals. * Architecture deep dive: current-state review, target architecture, risk register, performance/cost plan, reliability plan (SLAs, incident response). * Data platform & catalog systems: ingestion/normalization pipelines, “messy data → trusted master catalog,” search/SEO at scale. * AI in production (pragmatic): where LLMs help, where they don’t, guardrails, evaluation, rollout plan. * Leadership coaching & training: first-time manager enablement, delegation, hard conversations, hiring, and running teams in high-pressure environments. What you’ll get? Clear written outputs (docs/diagrams), quantified tradeoffs, and a plan your team can execute: priorities, milestones, and “what to stop doing.” What I delivered? 1. Technical Strategy & Architecture * Rapid Scaling: As CTO, I delivered 20x faster page loads and SEO-indexed 250k pages in 60 days for a new e-commerce platform. * Operational Excellence: At Amazon, I managed Tier-1 services handling 100,000+ requests/second with 99.9% availability and <20ms p90 latency. * Cost & Performance Optimization: Re-architected legacy systems to cut latency by 50% and reduce infrastructure costs by $2M/year. * Modern AI Integration: Implemented LLM-powered diagnostics and AI-driven catalog enrichment (image-to-text, automated translation) in production environments. 2. Engineering Leadership & Org Design * Team Building: Scaled a remote engineering org from 0 to 12 FTE in 3 months and led Amazon organizations of 50 FTE. Leader of leaders. * Talent Development: Mentored 25+ leaders and conducted 300+ interviews. Consistently ranked in the top 25% of Amazon managers for leadership and inclusion. * Efficiency: Improved time-to-production by 98% via automated CI/CD and chaos testing. 3. Executive Consulting & Coaching * For Startups: I provide architecture deep dives, 1–3-year strategic roadmaps, and "0-to-1" organizational setup. * For Leaders: I run a specialized consulting practice with multi-week programs designed to transition senior engineers into high-performing managers. Technical Profile * Domains: E-commerce, Supply Chain (SCOT), Fintech (POS), Big Data, and Integrated Circuits. * Tech Stack: Distributed Systems, AWS (Bedrock, etc.), Java, C/C++, Python, LLM orchestration, full-stack development, SEO * Education: PhD in Engineering
