I'm Olga, an Account Development Representative who genuinely loves the early stages of a deal. I find energy in research, pattern recognition, and crafting outreach that actually resonates.

My background is in B2C sales, customer and tech support. I've built qualification frameworks from scratch, refined multi-touch sequences, and learned to cut through noise by being genuinely useful to prospects rather than just persistent.

Things I've built

Working software, live on the internet — not slideware. Every project below runs as a live demo you can open right now, with the full source on GitHub. The write-ups tell you what each one does. How — and why it works — is a conversation.

Lead Scoring Engine: which leads convert — and why

A machine-learning engine that scores every lead the moment it arrives — and, unlike most models, explains itself: for every score, it shows exactly which signals pushed that lead up or down. In the demo, move the sliders and watch a lead go from ice-cold to sales-ready in real time.

Here’s the hook: the signals that matter most are not the ones most teams chase. The demo shows you the what. The how is worth a call.

Superfan Revenue Engine: RevOps for an industry that’s never heard of it

Revenue-operations thinking applied where nobody applies it: independent music. The engine scores fans by expected value the way sales teams score leads — then an optimizer plans a tour that beats the obvious big-city routing on the same budget. In the demo, move the budget slider and watch the plan reshuffle itself.

Why it consistently outperforms the naive plan is the part I don’t write down. Ask me.
