my works
timeline of projects and milestones
online courses had me drowning in endless moodle quizzes. 90% clicking, 10% learning. pure busywork.
quanta is a chrome extension that turns ai into your quiz-crushing sidekick. what started as a weekend experiment became surprisingly effective.
the extension integrates seamlessly into any quiz page. no complex ui or unnecessary features, just focused functionality that gets the job done.

- chrome store: eventually, maybe.

the "get answer" button
this is the core of it. a little button slides in right on each question. you click it, it does its thing, and bam! you get the answer.
here's the play-by-play: it sniffs out the question and options, pings whatever ai model you've hooked up, and gets back not just the answer, but a confidence score and the "why" behind it. it highlights the right choice, and if you're feeling lazy, it'll even click the radio button or checkbox for you.
answer all (the "yolo" button)
clicking one by one is cool, but sometimes you just want to let it rip. that's what "answer all" is for.
i even styled it to look exactly like the other moodle buttons, so it feels totally native. it's my favorite little detail.
it runs through every question on the page. but it's not dumb. it uses a confidence threshold you set. if the ai is like, 95% sure, it'll lock it in. if it's iffy (say, 60%), it'll just highlight the answer so you can give it a final look before submitting. you're still the boss.
the thinking stream
ever wonder what the ai is actually thinking? i was curious, so i added a streaming feature. you can literally watch the model's reasoning unfold in real-time. it's kinda mesmerizing and way better than just getting a black-box answer.
settings panel
the ai space moves ridiculously fast. a new, better model drops every other week. i hate being locked into one ecosystem, so i made quanta provider-agnostic.
bring your own api key from openai, claude, gemini, perplexity, or hook it up to openrouter to access a ton more. your keys are stored locally in your browser, never touching my servers.
you can also toggle stuff like the thinking stream, web search, auto-selecting answers, and tweak the confidence score. your workflow, your rules.
what's next
honestly, this was just for me at first. but if people dig it, maybe i'll polish it up for the chrome store.
if you want early access or have some ideas, hit me up. always down to talk.
anonymous indonesian psychology chat application powered by gemini and integrated with alodokter health information.
mental health information in indonesian is surprisingly hard to find. most resources are behind paywalls, require accounts, or deliver generic responses that miss the mark.
i wanted to build something different. waras combines the vercel ai sdk with retrieval-augmented generation (rag) to deliver fast, anonymous, and contextually-aware mental health support in indonesian.
building with rag
the core challenge: creating an ai assistant that provides accurate, contextually relevant mental health information rather than generic responses.
data collection i scraped 71 psychology articles from alodokter to create a reliable indonesian-language knowledge base. the content covers various mental health topics with medical accuracy.
technical implementation built with next.js and shadcn/ui for the frontend, using the vercel ai sdk for seamless integration with google's gemini model. the streaming responses create a natural conversation flow.
rag architecture when users ask questions, waras performs vector search across the scraped articles to find relevant context. this information is fed to gemini alongside the original prompt, ensuring responses are grounded in reliable medical information rather than ai hallucinations.
privacy-first design
most mental health platforms require accounts, have poor indonesian support, or deliver generic advice. waras addresses these issues by offering:
- anonymous sessions with no data collection
- native indonesian language support
- fast, responsive interface
- contextually relevant responses based on medical literature
this project demonstrates how specialized ai tools can be built efficiently without compromising user privacy or requiring extensive resources.
polaroidthis.studio
a dead-simple way to make those minimalist movie polaroids you see everywhere. no photoshop, no templates, just one click.
so i kept seeing these sick polaroid-style movie posters all over twitter and pinterest. you know the ones that are super minimal and clean. i figured it'd be easy to make one myself.
i was wrong.
searched online and all i found were sketchy photoshop templates, tutorials behind paywalls, or canva templates that just didn't hit the same. everything was either too much work or looked cheap. the aesthetic was just off.
i'm a builder, so when i see a problem, i build the solution. i got tired of the gatekeeping and decided to just make the tool i wanted. something dead-simple: search a movie, click a button, and get a perfect, high-quality polaroid poster. no bullshit.
so yeah, polaroidthis is basically the tool i wish existed when i was hunting for it. built it to scratch my own itch, but hopefully, it helps you out too. no more bullshit tutorials, just make the poster and go.
