Squarespace.com

About the role

From September 2024 through early 2026, I was a senior software engineer (frontend) on Squarespace's marketing web — the public squarespace.com experience that millions of prospective customers see first. This is the company's primary consumer acquisition channel, so performance, reliability, and conversion quality were non-negotiable.

What I shipped

• Performance & page weight: Built and optimized high-visibility surfaces, improving Core Web Vitals and reducing page weight across key marketing pages.
• CDN migration: Led migration of squarespace.com's JavaScript and CSS asset pipeline to a new CDN domain — coordinating a zero-regression rollout across frontend, infrastructure, localization, and third-party translation teams.
• Marketing experiences: Prototyped and shipped high-impact pages in close collaboration with design and product, using experimentation and analytics to refine UX on conversion-focused surfaces.
• Design QA tooling: Built internal developer tooling, including a Chrome extension integrating with Figma's API to catch spec discrepancies on live pages and cut manual design-to-code review overhead.
• Stakeholder alignment: Presented infrastructure migration plans, rollout strategy, and tradeoffs to engineering leadership — aligning cross-functional teams on risk mitigation and launch readiness.
• Comparison & acquisition pages: Continued work on competitive comparison pages and other high-intent surfaces that help evaluators choose Squarespace with accurate, fast, persuasive content.

Technical highlights

• Component-driven development: Reusable UI patterns across the marketing codebase for consistency and maintainability at scale.
• Cross-functional delivery: Regular collaboration with SEO, content, design, product, and infrastructure — especially during the CDN migration.
• Experimentation culture: A/B tests on copy, layout, and feature emphasis on high-traffic landing pages.

Impact

squarespace.com is one of the most visible surfaces in the company. My work focused on making that first impression faster, more reliable, and easier to iterate — while unblocking future delivery improvements through infrastructure and tooling investments.
