Hi, I'm Mike

Senior Product Manager | Enterprise Platform

20+ years building data-driven products — from analytics pipelines and machine learning systems to enterprise SaaS platforms used by millions. I bridge product strategy with hands-on software engineering and empowering leadership.

About Me

With over 20 years across product management, data analytics, and software engineering, I've led platform and analytics initiatives at Semrush, Sky, Snowplow, Ometria, and Webtrends — scaling products used by millions of users and building data systems from the ground up.

I stay hands-on: writing Python and SQL, building ML models, and shipping side projects for fun (see below). That mix of strategic product thinking and real technical depth is what I bring to every team I join.

Career Highlights & Projects

A mix of the hard problems I've led teams through at work, and the personal projects I build to stay sharp and curious.

Current Role Highlights

Report Studio

Report Studio

Challenge: Our legacy reporting tool was built for speed, not scale — no cross-product data, filters that reset, elements that quietly went stale. Fixing it meant moving hundreds of live enterprise clients off years of built-up reports.

Approach: Led the cross-product rebuild and designed an honest, opt-in migration path. When manual rebuilds proved too slow at scale, I built tooling to auto-match legacy elements — pushing real coverage from a flawed 54% estimate to a verified 87%.

Impact: 50-client beta to GA with over 50% adoption in the first month.

"Good migrations aren't about hiding the hard parts — they're about giving people real tools to move forward."

Element API

Element-Level API

Challenge: An internal-only API meant to power our own dashboards had been quietly adopted by power-user enterprise clients pulling raw data into their own BI tools — no rate limits, no docs, and a handful of accounts driving most of the load.

Approach: Built a usage-limits strategy from real traffic and cost data, then aligned engineering and commercial teams around a phased rollout — warnings before enforcement, with a clear upgrade path instead of a cutoff.

Impact: Protected $500k+ in enterprise MRR and avoided ~$10k/month in infrastructure cost, with limits signed off up through the CPO.

"The best fix for an accidental product isn't to kill it — it's to give it real guardrails and a real home."

Collaboration Suite

Enterprise Collaboration Suite

Problem: SEO teams needed deep collaboration between internal teams, the platform, and external experts — not a bolt-on help widget.

Solution: Led development of an integrated suite combining chat, Kanban tasks, meeting booking, smart docs, and an expert marketplace, navigating build-vs-buy across 6+ tool categories.

Impact: Renewing clients used the suite more than clients who churned, and it was one of the highest-rated tools with our support team — later sunset in favor of Intercom as the business consolidated support tooling.

"Proof a fast-moving team can build something clients genuinely value, even when the business later chooses a different path."

Side Projects & Experiments

With AI-assisted tooling, I can test an idea in a weekend instead of a quarter. Not everything here is meant to become a business — most of it is just me staying hands-on with code and following my curiosity. Two get the deeper write-up below; a few smaller ones are linked at the end.

Predictive ML

Predictive ML Experiments

Challenge: Building full end-to-end data pipelines in notoriously difficult prediction domains — horse racing and forex trading.

Applications: A horse racing predictor (48% hit rate) that collects race data and trains daily models, plus EUR/USD trading signals (50% profitable entry accuracy).

Learning Focus: Real-world data collection and parsing, feature engineering for time-series predictions, and model performance in high-noise environments.

"Sharpens my data pipeline skillset and satisfies my curiosity in what's possible with data and compute."

AI Agent Platform

Helperee.com

Evolution: Started as a learning project to build a PDF chat tool; now a long-running experiment in agentic project management and data cataloging.

Status: Early and unhurried. I work on it in the background as a genuine long-term bet, not a product I'm pushing to market — it may take years to find real shape, if it ever does.

Why it's here: It's where I test AI agent patterns with real code rather than just theory.

"A slow-cooking experiment — valuable for what it teaches, whether or not it ever becomes a product."
