Operations leader who builds the systems that let founders stop firefighting. 20+ years leading operations, from certified manufacturing plants (500+ people, ISO 9001 / IATF 16949) to, most recently, building the complete operating system for an AI-native fintech startup from zero as Chief of Staff.
What that looks like in practice: I design the operating cadence (PDCA cycles, weekly reviews, accountability frameworks), the governance layer (SOPs, policies, approval gates), and, increasingly, the AI agent architecture that runs parts of it: Slack-based standups, automated reporting, meeting-to-knowledge pipelines, and clear rules for what agents can decide versus what needs a human. I use Claude/Cowork daily, not as a novelty but as core infrastructure.
Earlier in my career I ran 300-500 person manufacturing operations at Bourns Inc., leading ISO/IATF certification efforts, driving a 30% output expansion via a $3M capital investment, and cutting operational costs by 25% through Lean Six Sigma. That same discipline (process ownership, root cause analysis, no initiative without a named owner) is what I now apply to leaner, faster, AI-augmented organizations.
I currently manage a ~50-project portfolio across a multi-entity corporate group, using a Waterfall/Kanban hybrid methodology I designed myself: full artifact set (charters, RACI, risk logs, UAT gates, lessons learned), so nothing depends on tribal knowledge.
If you're a founder or ops leader who needs someone to turn "we're doing this in our heads" into a system with clear owners, evidence, and, where it makes sense, AI agents doing the repetitive parts. That's the work I want.

Operations & Data Specialist | Process Engineer | Data Analyst

Is your growth stalled by unclear ownership, fragmented workflows, and endless revisions? Are you constantly running behind schedule or facing unmet deadlines? Are your clients unsatisfied? Most operational inefficiencies aren’t obvious, but they quietly drain your resources and stall progress.
I solve these operational headaches by turning scattered efforts into structured, reliable processes that scale smoothly. With many years as a Certified Data Analyst and Process Engineer supporting founders and operations across North America, Europe, and Latin America, I cut through operational noise, providing clarity and efficiency.
Less Chaos. ➜ More Clarity. ➜ Faster Growth.
▂▃▅▇█▓▒ How I boost your operational efficiency ▒▓█▇▅▃▂
🚀 𝗔𝗰𝗰𝗲𝗹𝗲𝗿𝗮𝘁𝗲𝗱 𝗗𝗲𝗹𝗶𝘃𝗲𝗿𝘆: Workflows designed for clear accountability, minimal oversight, and rapid turnaround. I design workflows with tools like Asana, ClickUp, or Notion, tailored to your team's structure.
⚙️ 𝗛𝗶𝗴𝗵-𝗤𝘂𝗮𝗹𝗶𝘁𝘆 𝗢𝘂𝘁𝗽𝘂𝘁𝘀: Built-in quality control, tighter scoping, fewer revisions. Using DMAIC (Define, Measure, Analyze, Improve, Control) and Lean Six Sigma principles, I build in quality assurance from the start.
📊 𝗗𝗲𝗰𝗶𝘀𝗶𝗼𝗻-𝗥𝗲𝗮𝗱𝘆 𝗔𝗻𝗮𝗹𝘆𝘁𝗶𝗰𝘀: I create custom dashboards in Power BI, Tableau, or Looker Studio that deliver actionable insights without noise.
💸 𝗥𝗲𝗱𝘂𝗰𝗲𝗱 𝗕𝘂𝗿𝗻 𝗥𝗮𝘁𝗲: Smart scoping and tighter tracking that directly impacts your bottom line. By combining Time-Driven Activity-Based Costing and KPI dashboards, I track where resources are bleeding and recalibrate scopes accordingly.
🔥 𝗟𝗲𝘀𝘀 𝗡𝗼𝗶𝘀𝗲, 𝗠𝗼𝗿𝗲 𝗥𝗲𝘀𝘂𝗹𝘁𝘀: Independent management of cross-functional tasks, reducing your daily operational burden. I manage cross-functional ops in tools like Slack + Airtable automations or Zapier, reducing dependency on meetings.
If you’re ready for your operations to accelerate your business rather than hold it back, let's connect!
I help e-commerce and DTC brands turn messy, founder-dependent operations into systems that scale and protect margin while they grow.
Over 15 years I've twice climbed to COO. Along the way I built a customer-service operation from a single daily email into a multichannel team handling 100–300 emails a day cutting first-response time from 72 hours to under 6, and holding satisfaction above 89% while the business grew roughly 600%.
Today I run the unglamorous engine that lets founders stop firefighting: SOPs, vendor and supply-chain management, KPI dashboards, subscription and fulfillment operations (Shopify, Recharge), QA and supplier integrity, and the process redesign that turns a good month into a repeatable one.
I'm PMP-certified and a Lean Six Sigma Black Belt but what clients hire me for is judgment: knowing which 20% of fixes drive 80% of the result, and executing without needing to be managed.
If you need a senior operations partner fractional COO, PMO lead, or a full ops overhaul!
Let's talk.
