Cover image for I got tired of two
I got tired of two things: the nightly "what should I watch?" paralysis across a dozen streaming apps, and rating systems where a single score doesn't really tell you enough about a film. So I built Quartile (quartilefilm.io (http://quartilefilm.io)), a film discovery and rating platform. The core idea: instead of one ambiguous score, every film is broken into the five elements that actually matter — Plot, Acting (Narration for docs), Cinematography, Novelty, and Ending — each scored on a 1–4 scale: Well Below Average, Below Average, Above Average, Well Above Average. There's deliberately no neutral "average" middle — it forces you to actually take a position on each category instead of lazily defaulting everything to the middle, which keeps the ratings honest. Those five combine into a consistent score out of 10, but you can also see what each category scored, which helps you understand why a film is rated what it is. Sometimes a movie is really good but the ending or the acting is terrible, so the overall score isn't that high — and without the Quartile system you'd have no way to know that, because a single number can't tell you. That's exactly why I built it: I wanted to know why a film was rated what it was. Essentially it's a formula and some real quality control for how a film gets rated. The coolest part is it lets you filter in really cool ways. You can filter by Top in any category — so Top Cinematography shows only films rated Well Above Average (4) there. Top Novelty is one of my favorites, and one of the most unique filters we offer. You can also stack these with genre — so Top Novelty in horror, or Top Cinematography in sci-fi — which is where it gets genuinely useful for finding something specific to your mood. On top of the rating system you can log films you've seen, build and share playlists, and follow other users to see what they're watching. The same way you follow friends with good taste in music to find new songs on Spotify, film is a matter of taste too — you can follow friends with good taste in certain genres to find movies you'll actually like. It's in beta right now. Would love feedback from this crowd and general thoughts. Of course I'd be stoked if you made a profile and started rating movies and building playlists too — I'm going to grandfather in the first active users and give them something really cool on their profile eventually to mark that they were one of the first Quartile users.

As a Senior Full-Stack Developer, I focus on: Building clean, maintainable frontends with strong UX foundations Designing resilient backends, APIs, and data models Making pragmatic tech decisions that hold up over time Shipping fast without cutting corners What I typically work on: SaaS platforms & internal tools Complex dashboards and data-driven apps API-first systems and integrations Performance, refactors, and technical debt cleanup I’m opinionated about code quality, architecture, and ownership but flexible about tools and stacks when the problem calls for it. If you need someone who can own features end-to-end, communicate clearly, and think beyond just “making it work,” let’s talk.
