Deep dive
The project that proves the range
Sirius Dog Fitness isn't a landing page. It's a full-stack SaaS with authentication, Stripe subscriptions, AWS S3 media hosting, an activity calendar, a gamified points system, and a 15-step mobility test — built alone, end-to-end.
"Better than I could have hoped for."

01 · The challenge
The technical scope was significant: the app required a monthly subscription-based licensing system, cloud media hosting for videos and images, email automation, a gamification system with paw points, leaderboards and achievement badges, a 15-question mobility assessment test, informational 'Rest Stop' sections, and complex user management for two distinct target audiences.
02 · The build
I built the entire app as a Next.js full-stack solution with the following integrations: AWS S3 for video and media hosting, Stripe for monthly payments and license tiers, Resend for the email system, and MongoDB as the database. Features built: guided fitness paths with text/images/video, the Dog Days activity calendar, paw point scoring, leaderboards, achievement badges, and the mobility assessment test.
03 · The result
The client received exactly the app she had dreamed of. Result was, in her own words, better than she could have hoped for. The app is now live in production, actively serving both companion dog owners and sport & hobby dog enthusiasts.

About these references
Every project is a real client with a real problem. No mockups, no 'coming soon' — just live sites that are measured on whether they actually earn their keep.

How I work
Scope gets defined before code. Then I ship in focused weekly milestones so you see progress, not slideshows. One developer, one accountable point of contact.

What comes next
Start with a free custom mockup — you see exactly what your site could look like before you commit to anything. If it lands, we go from there.

Where to continue if you are planning your own project
Most projects start with one of three needs: a new business website, a redesign of an outdated site, or stronger search visibility. These pages help you judge the right scope before requesting a quote.
