I help building owners, developers, and design teams close the gap between how a building is modeled and how it actually performs — combining building energy modeling with mechanical (MEP) design to reduce energy use, operating costs, and carbon impact. Most freelancers do either the energy model or the mechanical design. I do both, which means the two actually align — and you don't need to coordinate between two separate hires. Why clients work with me: • Integrated energy modeling + MEP design under one roof • Code-fluent across ASHRAE 90.1, NECB, Title 24, IECC, BREEAM, and Passive House • Data-driven, fully documented, on-time deliverables 🖥 Energy Modeling & Sustainability EnergyPlus, DesignBuilder, IESVE, PVsyst · ASHRAE 90.1 / Title 24 / NECB / IECC compliance · energy audits (ASHRAE 211, ENERGY STAR) · 179D support · daylight, thermal comfort & PV feasibility studies 🏢 Mechanical (MEP) Design HVAC system design (VRF, AHU, chillers, boilers, heat pumps) · heating & cooling load calculations · plumbing, fire protection & gas systems · full Revit MEP modeling with clash detection · equipment selection, BOQ & specs 🏊 Specialized: Pool & High-Humidity Spaces Hydraulic design, equipment sizing, and HVAC for pool halls and spas 📊 Engineering Analysis & Automation FEM & CFD simulation · MATLAB modeling · Python automation for engineering workflows 📩 Let's bring your high-performance building vision to life — message me to discuss your project.

Most Squarespace websites don’t have a traffic problem — they have a conversion problem. They look decent. They load (sometimes). But when someone lands on the page, nothing really happens. No clear direction, no structure guiding the visitor, no reason to take action. So the result is predictable: people visit… scroll… and leave. That’s the gap I focus on. I don’t just “build websites.” I work on Squarespace websites that are designed to guide behavior — turning visitors into leads, bookings, and actual clients. Whether it’s a full website build, a redesign, or fixing a poorly performing layout, the goal is always the same: *make the site work, not just exist.* When I take on a project, I look at three things first: 1. How fast the website loads (because slow Squarespace sites kill conversions fast). 2. How the structure flows (most sites are confusing, especially on Squarespace). 3. And how clearly the offer is presented (this is where most businesses lose money). Once those are fixed, everything else — design, SEO, responsiveness — starts working together instead of against you. I work on Squarespace, handling projects like: ✅Squarespace website design using HTML/CSS or clean theme builds, ✅Squarespace 7.1 websites using Fluid Engine with a modern, structured layout, ✅Full website redesigns for outdated or underperforming sites, ✅Landing pages built specifically to convert traffic into leads or sales, ✅Website speed optimization (especially for slow sites, ✅On-page SEO setup so your site is actually discoverable, ✅And fixing broken layouts, responsiveness issues, or messy sections. Most clients who reach out are usually in one of these situations: ✔Their website looks outdated and doesn’t reflect their brand anymore. ✔Their Squarespace site feels “off” but they can’t explain why. ✔Their site is slow, cluttered, or hard to navigate. ✔Or they have traffic… but no real conversions. If that sounds familiar, then we’re probably a good fit. I keep the process simple. No unnecessary back and forth, no overcomplication. You tell me what you’re trying to achieve, and I’ll break down the clearest structure and direction for your website — before we even start. If you’re looking for a Squarespace website that actually performs — not just something that “looks okay” — SEND ME A MESSAGE I’ll take a look at what you have (or what you’re planning), and tell you exactly what I’d improve or build differently.
