Fractional CTO and hands-on engineering leader — 25+ years building, scaling and securing SaaS platforms, with three acquisitions behind me. I turn legacy systems into cloud-native architecture on AWS and Azure, and build the AI and agentic systems that set products apart. I work as both a strategic partner and a builder, so you get high-level direction and someone who ships the hard parts. What I bring: ⚡ Cloud architecture & modernization — Migrated a mission-critical platform from a monolithic instance to distributed serverless AWS (Fargate, Aurora, ALB, WAF), enabling a 50x increase in tenant capacity for a Tier-1 financial client. 🤖 AI & agentic systems — Multi-agent workflows and LLM apps on the Claude API: shared memory, RAG with pgvector, and prompt-cost optimization. Plus applied ML and computer-vision pipelines. 📱 Full-stack & mobile — .NET, React & React Native (iOS + Android), Firebase, Google Cloud. 🎯 Technical leadership — Product roadmaps, ISO 27001 security posture, CI/CD, and engineering cultures that scale teams and pass acquisition due diligence. Whether you need a fractional CTO to set technical direction or a senior engineer to build the thing, I do both. Tell me what you're building — let's figure out the fastest path to shipping it.

You're spending real money on ads. But GA4 says one number, Google Ads says another, Meta says a third, and your CRM doesn't match any of them. So your team picks whichever numbers and attributions that support the decision they already wanted to make — and calls it "data-driven." That's not a reporting problem. That's a measurement problem. I find what's actually causing the discrepancy and fix it. 100% success rate - Top 1% on Upwork. Rated by over 100 happy clients ⭐️⭐️⭐️⭐️⭐️ --- 𝗜𝗳 𝗮𝗻𝘆 𝗼𝗳 𝘁𝗵𝗶𝘀 𝘀𝗼𝘂𝗻𝗱𝘀 𝗳𝗮𝗺𝗶𝗹𝗶𝗮𝗿, 𝘄𝗲 𝘀𝗵𝗼𝘂𝗹𝗱 𝘁𝗮𝗹𝗸: - Google Ads, Meta, GA4, and your CRM all show different conversion numbers — and you're spending five or six figures a month not knowing which one to believe - You server-side tracking or Meta CAPI were 'set-up' , but the numbers still look wrong - You don't leverage server-side tracking at all - Your dashboards look polished, but you can't actually tell which channel is driving revenue - A migration, redesign, or consent banner rollout quietly broke your tracking - You're scaling paid media but don't trust the data enough to make confident budget calls --- 𝗡𝗼𝘁 𝘁𝗵𝗲 𝗿𝗶𝗴𝗵𝘁 𝗳𝗶𝘁? I work best with businesses that are past the basics — running real ad spend, dealing with real complexity, and needing someone who can diagnose and fix what's actually broken, not just install pixels. If you need the cheapest implementation or a quick tag drop, I'm probably not your guy. If that sounds like your situation, let's talk. --- 𝗛𝗲𝗿𝗲'𝘀 𝘁𝗵𝗲 𝗽𝗮𝘁𝘁𝗲𝗿𝗻 𝗯𝗲𝗵𝗶𝗻𝗱 𝗮𝗹𝗹 𝗼𝗳 𝘁𝗵𝗲𝘀𝗲: Every engagement starts with what I call The Tracking Diagnostic — a structured review of your full measurement chain: tags, triggers, consent, data layer, platform configs, server-side events. I map how everything connects (and where it doesn't). You get a clear breakdown of what's broken, what it's costing you, and a prioritized fix plan — before any implementation begins. --- 𝗪𝗵𝗮𝘁 𝘁𝗵𝗶𝘀 𝗹𝗼𝗼𝗸𝘀 𝗹𝗶𝗸𝗲 𝗶𝗻 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: 🔹 SaaS company losing 40% of conversions due to SPA navigation breaking GA4 events → Full tracking restored in 5 days, CAC dropped 30% 🔹 Ecommerce brand seeing 2.3× more conversions in Meta than GA4 → Server-side deduplication brought platforms within 8% of each other 🔹 Lead gen agency couldn't connect form fills to closed deals across 23 client accounts → Built CRM-to-ad-platform pipeline, attributed $2.1M in previously invisible revenue --- 𝗪𝗵𝗮𝘁 𝗜 𝗰𝗮𝗻 𝗵𝗲𝗹𝗽 𝘄𝗶𝘁𝗵: 𝘍𝘪𝘹 & 𝘋𝘪𝘢𝘨𝘯𝘰𝘴𝘦 - Tag audits, broken conversion tracking, data discrepancies between platforms, consent mode issues, GA4 misconfigurations 𝘐𝘮𝘱𝘭𝘦𝘮𝘦𝘯𝘵 & 𝘉𝘶𝘪𝘭𝘥 - GTM setup and governance, GA4 implementation, server-side tracking (Meta CAPI, TikTok Events API, Google Ads), cross-domain and funnel tracking, data layer architecture 𝘙𝘦𝘱𝘰𝘳𝘵 & 𝘚𝘤𝘢𝘭𝘦 - Looker Studio dashboards, BigQuery exports, offline conversion tracking, CRM-based attribution, ongoing measurement QA --- 𝗥𝗲𝗮𝗱𝘆 𝘁𝗼 𝗳𝗶𝘅 𝘆𝗼𝘂𝗿 𝘁𝗿𝗮𝗰𝗸𝗶𝗻𝗴? If your numbers don't line up and you're not sure where the problem starts — send me a message with 1. your website or funnel URL 2. the platforms involved 3. what looks wrong in the data 4. what outcome you need to measure I'll tell you what I think is going on before we discuss any engagement. Every engagement starts with The Tracking Diagnostic — a structured review of your full measurement setup, where it breaks down, what it's costing you, and exactly what to fix first. You'll have clarity before any implementation begins. Drop me a message.
