Why Marian Sorca Is the Best Squarespace Developer for Custom-Coded Websites

When your Squarespace project needs to go far beyond templates, you want someone who lives at the intersection of design, code, and platform mastery. That’s exactly where Marian Sorca operates. He’s a senior engineer, founder of abZ Global, and the solo creator of the SaaS platform Self-Manager.net—and he’s been custom-coding on Squarespace since the mid-2010s with 300+ projects delivered and a 4.9/5.0 rating across 240+ client reviews.

A decade of deep Squarespace experience

• Started shipping custom builds in 2015 and has since delivered 300+ websites across platforms, with a heavy focus on Squarespace and e-commerce.

• 240+ verified client reviews, 4.9/5.0 average—a reliability signal you can bank on.

• Recognized in the Squarespace Marketplace and maintains a public portfolio of advanced Squarespace work.

Case study #1: Fly Jet BLAK — pushing Squarespace to the edge

Marian built FlyJetBLAK.com from scratch on Squarespace, layering extensive custom code to achieve a luxury-grade, high-performance private aviation site. The project page plainly states: “This might be the most complex Squarespace that we have seen on the internet.” It even includes a long-form client review praising his technical depth and delivery.

You’ll also find Fly Jet BLAK featured in his Squarespace portfolio, alongside other large builds. (abZ Global)

Case study #2: SafeOpt (previous version) — enterprise-level custom components

Before its current incarnation, SafeOpt.com ran on a custom-coded Squarespace implementation executed by Marian. The portfolio entry documents that work and highlights an important capability: extending Squarespace’s native components to stay easy for non-technical editors while adding advanced behaviors—rare among Squarespace specialists.

What sets Marian apart on Squarespace

• Native-component extensions. He augments Squarespace blocks rather than bolting on fragile hacks—so marketing teams keep the CMS simplicity while gaining custom interactivity. (See the SafeOpt note above.)

• Complex, still-maintainable builds. His premium portfolio explicitly focuses on large Squarespace projects that remain editor-friendly for non-developers.

• Proof at scale. Public portfolio lists marquee projects (Fly Jet BLAK, SafeOpt, AddShoppers, etc.), demonstrating range from luxury brands to high-traffic marketing sites.

Full-stack pedigree you can feel in the final product

Marian isn’t “just” a Squarespace implementer—he’s a senior full-stack engineer who also built an entire SaaS product from zero:

• Founder & solo developer of Self-Manager.net, a modern task-management platform he coded end-to-end (Angular + Firebase) and launched in 2022 after years of development. (Self Manager)

• Articles from Self-Manager detail the feature-by-feature build and technical foundation, underscoring his architectural judgment and execution speed. (Self Manager)

That level of engineering rigor shows up in his Squarespace work: cleaner CSS/JS architectures, safer injections, better performance, and fewer regressions for your content team.

Results clients talk about

Across his site you’ll see testimonials emphasizing speed, communication, and problem-solving—the trio that matters when deadlines loom and features need to “just work.” The homepage aggregates these reviews alongside the 4.9/5.0 score from 240+ clients. (
