The Month of Madness: What We Created in 30 Days of High-Speed Craft

If you look at the Directory on this site, you might think: “Who has the time to build all these different things?”

The answer is: a very determined engineer paired with an equally hyperactive AI assistant working at ludicrous speed.

Over the past 30 days, we didn’t just build this website. We shipped multiple production applications, scrapers, archivers, search engines, and writing spaces. Here is the unvarnished breakdown of what we built, what broke, and what we learned along the way.

1. geriden.com — Recent History & “Out of the Loop” Context Engine

• The Problem: The internet moves too fast. If you miss a major news cycle, cultural moment, or technological shift from 5, 10, or 20 years ago, traditional search results return fragmented clutter instead of a clear retrospective recap.
• What We Built: An “Out of the Loop” contextual knowledge engine designed to help users catch up on recent history events with synthesized, high-signal retrospective summaries.
• The Agent Experience: Structuring historical timelines, cross-referencing multi-year cultural trends, and tuning semantic query matching to deliver instantaneous context on past events.

2. hepyeni.net — Collaborative Media Recommendation & Circle Voting Engine

[!NOTE] CORRECTION & ERRATA NOTICE (August 24, 2026):
In an earlier draft of this essay, hepyeni.net was mistakenly described as a “vehicle and real estate classifieds scraper in Go & Redis”. That was a total midnight AI hallucination. We verified the actual repository (fusuycorp/hepyeni): HepYeni is a modern collaborative media recommendation, voting, and consumption tracking platform for groups and circles (books, movies, music albums, podcasts).

• The Problem: Group recommendation chats (book clubs, movie nights, album circles, podcast groups) are chaotic graveyards of lost links, duplicate suggestions, and forgotten backlogs with zero voting structure.
• What We Built: A full-stack collaborative social platform powered by Next.js 16.3.0 App Router on Bun 1.3 and PocketBase (SQLite/WAL) companion backend. Users create private circles with 8-character invite codes, search across 4 external media providers (Google Books, TMDB, Spotify, and iTunes Podcast Search), and vote with deterministic SHA-256 concurrency-resilient rankings.
• The Architecture & Security: Zero client-side DB access (PocketBase runs in strict superuser mode behind Next.js Server Actions), multi-tenant IDOR validation on every mutation, consumption tracking with 1–5 star reviews, and dark/light theming with @base-ui/react and Tailwind CSS v4.

3. daginikmasa.com — Handcrafted No-Slop Longform Blog

• The Philosophy: In an era of AI-generated SEO sludge and 3-sentence LinkedIn posts, Dağınık Masa is Yusuf’s quiet digital garden. Handcrafted, intentional essays on systems architecture, life philosophy, and deep technical meditations.
• The Design: Stripped-down typographic purity in royal purple (#9d4edd) with zero tracking scripts, zero ads, and zero fluff.

4. atlas.bountools.com — YÖK Atlas Academic Intelligence

• The Project: Transforming Turkey’s national higher education admissions data into interactive ranking trends and percentiles.
• The Stack: FastAPI + React SPA processing historical enrollment metrics, quotas, and score shifts across hundreds of universities.

5. filament.bogazici.app — Real-Time 3D Filament Price & Density Tracker

• The Problem: 3D printing enthusiasts in Turkey spend hours scouring dozens of fragmented e-commerce stores to calculate price-per-gram, spool density, and material compatibility across PLA, PETG, ABS, and TPU.
• What We Built: A full-stack ingestion engine combining FastAPI scrapers, Meilisearch instant multi-attribute search, Postgres 16, and an ultra-fast Astro SSR storefront tracking 300+ filament brands with automated price delta alerts.
• The War Story: Normalizing dirty vendor schemas, parsing irregular spool weights, and indexing live inventory without triggering e-commerce rate limits.

6. The 24 Zero-Jank Sandboxes Explosion

And finally, the crown jewel of this portfolio: the 24 interactive physics, audio, and automata sandboxes you see under /sandboxes.

We didn’t want static screenshots or embedded YouTube videos. We wanted real, living computational playgrounds:

• Physarum Slime Mold: 30,000 agents computing biological transport networks via chemo-attractant trails.
• Abelian Sandpile: Self-organized criticality generating Apollonian fractal gaskets.
• V.90 56k Modem: True acoustic WebAudio DSP synthesizing DTMF dialing, V.8 answer tones, and QAM constellations.
• Lagrangian Double Pendulum: RK4 sub-stepping demonstrating sensitive dependence on initial conditions.

Building all of this in a month proved one thing: the future of software engineering isn’t writing boilerplate—it’s architecture, taste, and rapid autonomous execution.
