About

Professional summary

I am a technical product leader and AI/ML engineer with nine years of experience building and operating Geolance end to end, from zero-to-one product discovery through production launch and continuous delivery.

I lead product strategy, roadmap validation, MVP delivery, and cross-functional engineering execution. I use production data, KPIs, customer input, cost telemetry, and latency metrics to prioritize product and technical investments.

My AI engineering experience includes autonomous multi-agent systems, LLM application architecture, RAG, vector search, self-hosted inference, prompt evaluation, model routing, fine-tuning, and voice AI. I have built an AI-agent product line with specialized agents and shared tools that can generate hosted websites from customer conversations.

I have deep hands-on experience in MLOps, DevOps, cloud infrastructure, and production security. My work includes Kubernetes, GitOps, CI/CD, GPU-based LLM serving, observability, disaster recovery, OAuth2, RBAC, payment systems, and zero-downtime blue-green deployments.

I also bring experience in accounting operations and digital marketing. I am a Canadian citizen based in Fort Erie, Ontario, open to relocation, and available with two weeks' notice.

Career history

Head of Product & AI Engineering Geolance Inc.

I define and validate the zero-to-one roadmap for an AI-agent product line with 17 specialized agents and more than 180 shared tools. The platform enables customers to describe a project in chat and receive a working hosted website without human involvement.

I own the SaaS product line end to end, including OAuth2 identity, Stripe and PayPal subscriptions, usage-based billing, a 64-entity CRM, enterprise storage, and real-time messaging across 181 data models and 114 services. I sequence lean MVP releases across backend, infrastructure, and security while maintaining frequent blue-green, zero-downtime deployments.

I lead decisions on LLM infrastructure using cost and latency telemetry. A self-hosted GPU cluster reduced LLM costs by an order of magnitude, while KV-cache and routing improvements reduced conversational latency from 7.4 seconds to 0.6 seconds; LiteLLM fallbacks preserve cloud-model routing flexibility.

I hire, onboard, and lead cross-functional developers, designers, and marketers. I prioritize with KPIs and user feedback, run Agile delivery processes, communicate with stakeholders, and coach engineers on GitOps-managed model pipelines.

Accounts Payable Livingston International

I reconcile agent statements and clear aged balances for more than $2 million in monthly multi-currency transactions. I match agent invoices with shipment files and rate agreements to ensure accounts reconcile in full.

My work focuses on accounts payable accuracy, balance resolution, and the validation of supporting financial and shipment documentation.

Marketing and Communications Manager Lerom Law

I created and managed the firm's digital marketing initiatives across brand awareness, website traffic, and lead generation.

I delivered Google Ads, email campaigns, and social media channel activities while working part-time alongside my role at Geolance.

Accounts Payable and Receivable Manager Media Profile

I worked full-time as an Accounts Payable and Receivable Manager for Media Profile in Toronto.

The role covered accounts payable and receivable management from July 2015 through April 2021.
