AI builds tools that ship your SaaS fast, then quietly leave it failing Core Web Vitals. I rebuild React & Next.js apps to achieve Lighthouse 90+, cut load times by up to 40%, and restore the search rankings that bloat is costing you. The AI Performance Paradox: code from Cursor, v0, or Copilot runs, but it ships with oversized bundles, layout shift, and main-thread blocks that wreck LCP, INP, and CLS. I audit that code and fix it at the architecture level, not with vanity tricks. Real outcomes I've delivered: 1. Rendering at scale — re-architected a simulation dashboard handling 7,000+ visual entities from severe lag to a smooth 60FPS with LCP under 2.5s. 2. Mobile Core Web Vitals — eliminated main-thread bottlenecks on a high-volume agritech SaaS, holding Lighthouse 90+ even under heavy data rendering. 3. Speed that cuts cost — optimized Node.js/Python pipelines to drop server infrastructure costs 4. 40% while keeping enterprise-grade stability. I optimize against real Google CrUX field data — what your actual users experience — not cached lab scores that look great and change nothing. If you've been burned by a "99 PageSpeed" that never moved your traffic, that's exactly the gap I close. Backed by a 100% Job Success, Top Rated record across 12 projects — "Outstanding experience! Highly recommended!" Want to know what's slowing you down? Invite me with your URL or Search Console access, and I'll send back a short Loom diagnosing your worst paint-cycle offenders, then a fixed-price plan to get you green.

I build enterprise platforms that last — not prototypes that get rewritten. My longest engagement is 6+ years with a single client, growing from 4 modules to a 9-module field operations platform. That's the kind of work I'm looking for. Recently I've been focused on AI systems engineering — RAG pipelines, LLM API integration, and WhatsApp-based AI agents running in production on SaaS platforms. 𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝 Complex, long-term platforms — not one-off fixes or quick integrations. My clients are typically building something serious: a multi-tenant SaaS, an enterprise operations platform, or a system where AI needs to work reliably in production, not just in a demo. They need an architect who can own the technical direction end to end, communicate clearly with non-technical stakeholders, and stay consistent over years — not months. If you have a well-defined short-term task, I'm probably not the right fit. If you're building something that needs to scale and last, let's talk. 𝐑𝐞𝐜𝐞𝐧𝐭 𝐏𝐫𝐨𝐣𝐞𝐜𝐭 𝐇𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐬 ✦ Engineering Field Operations (Calgary, Canada): Built a 9-module enterprise platform from the ground up for an automation engineering firm.

If that sounds like your project, let's talk.

Most data just sits there doing nothing. I make it work. I'm a Senior AI/ML engineer and data scientist with 10+ years designing intelligent, end-to-end solutions that save clients time, reduce errors, and uncover insights they didn't know they were sitting on. I bridge the gap between raw data and real results — combining advanced analytics with powerful automation to build systems that don't just work once in a notebook, but run quietly every day and earn their keep. I've shipped machine learning models, analytics workflows, and large-scale data pipelines for names like Dr Pepper, Mitel, and Sub-Zero Wolf, plus independent clients across real estate, marketing, and operations. Hand me a vague problem and a pile of messy data — that's exactly where I do my best work. I bring speed, precision, and adaptability to every project. What I bring to your project: • Machine Learning & AI — Predictive modeling, classification, forecasting, customer segmentation, image classification, and decision-support systems using scikit-learn, TensorFlow, and PyTorch. Comfortable across the full ML lifecycle: framing, feature engineering, training, evaluation, and deployment. • Agentic AI & LLM Systems — Autonomous AI agents and multi-agent workflows that plan, reason, and take action end-to-end. Building with LangChain, LangGraph, and the OpenAI/Anthropic APIs, plus RAG pipelines, vector databases (Pinecone, Chroma), tool/function calling, and MCP integrations that connect LLMs directly to your data and systems. • Data Science & Analytics — Statistical analysis, time-series forecasting, A/B testing, exploratory data analysis, and KPI tracking that translate numbers into clear, actionable insight. • Automation & Workflow — n8n, Make, ElevenLabs, Retell.ai, Custom Python tools, browser automation, API integrations, and Docker-based pipelines that eliminate repetitive manual work and run hands-free. • Web Scraping & Data Collection — Large-scale, structured extraction from public directories, social platforms, e-commerce catalogs, and APIs (Selenium, BeautifulSoup, Scrapy). • Data Engineering & Pipelines — Cleaning, validation, deduplication, and transformation into analysis-ready datasets; end-to-end ETL/ELT orchestration with Airflow. • Visualization & Reporting — Decision-ready dashboards and reports in Tableau, Power BI, and Python (Matplotlib, Plotly), Looker studio. • Enterprise Platform — Microsoft Copilot Studio, Salesforce, Google Vertex AI, AWS Bedrock, Azure AI, UiPath Select results: • Automated a real estate firm's invoice processing, cutting a 4-person workload by ~90%. • Built an image analytics pipeline for a major beverage brand to identify the content elements that drive engagement. • Scraped and structured 500k+ Instagram images for model training and analysis. • Delivered high-value datasets powering corporate marketing, sales targeting, and geographic analysis.
