Website design & development
Marketing sites and landing pages that look sharp, load fast, and turn visitors into customers — and stay easy for you to update.
- Conversion-focused design
- SEO & performance built in
- Animation & polish

The kind of work I build.
A studio that’s new in name, not in experience. These are real things I’ve designed, built, and shipped — shown here as examples of what I can build for you.
Kappa Sigma Network
A national member platform (200+ chapters) designed and built end to end — digital recruitment, service-hour tracking, events, chapter reporting, and an alumni career network — running as a web app plus native iOS and Android clients on one shared backend.
Bloom
An AI marketing engine for local businesses that writes ready-to-post promos every morning — tuned to the weather, nearby events, and each shop’s own slow days — then delivers them across Instagram, email, and SMS.
MeyaMade
A tool that converts images, text, and PDFs into machine-ready embroidery files through a custom Python stitch-generation pipeline — plus a live event mode for pop-ups, with QR sign-up, a guest designer, and real-time queue management.
Rhythm Talent Partners
A polished, animated marketing site for a boutique recruiting firm — fast, refined, and built around a tailored contact flow designed to convert high-value inquiries.
Puptracking
A real-time pet health and housetraining tracker for shared caretakers — live countdowns, daily timelines, and a full veterinary-record hub — delivered on the web and as an iOS app.
Salt Water
A water-chemistry tracker that reads a test strip straight from a phone photo using AI vision, then turns the readings into clear, prioritized maintenance steps.
Most of these are private or internal builds, so they’re shown as capability examples rather than public links. Want something similar? Let’s talk.
How it works
A clear path from idea to launch.
No mystery, no endless back-and-forth. You always know what’s happening, what’s next, and what it costs.
- 01
Discovery
We talk through your goals, your users, and your budget, then map a clear scope, plan, and timeline — in plain English, no jargon.
- 02
Design
I design the look and the flow and share it early, so the direction is right before a line of production code is written.
- 03
Build
I build in focused milestones with clickable previews at each step, so you always see real, working progress.
- 04
Launch & support
We ship to production on fast, modern infrastructure — and I stay on for updates, hosting, and whatever comes next.
About
From a creative studio to a software studio.
Campanelli Productions began years ago as a wedding photography, videography, and web design business — telling people’s stories and building their first websites.
These days I’ve gone all-in on the part I love most: building software. From my home studio in San Diego, I partner with small businesses and founders to design, build, and ship production web and mobile apps — the kind of tools people rely on every day.
That ranges from a fast marketing site to a multi-platform product serving hundreds of organizations. You work directly with me the whole way — no account managers, no handoffs, no mystery. Just clear communication and software that’s genuinely finished.
