A small shelf of things I'm building.

The maturity-measure platform — an epistemology-pluggable assessment engine that turns "how mature are we at X?" into a structured, evidence-backed score.

The Aksakal Compass platform — a consulting and benchmarking marketplace.

Photograph an antique and find out what it is, when it was made, and what it's worth — then keep the collection in one place. First category: vintage lighters. Every estimate shows its reasoning and asks for the one extra photograph that would settle the question. TR/EN, installable.

A 3D file wallet — carry your .obj, .stl and .blend models in your pocket, view them in a tactile studio, and hold them in AR. Interactive design prototype.

A pension app for people who don't know they're saving for a pension — only that they're chasing a dream. Three design directions (journey · constellation · story), in TR and EN. Mock data; built for flow and feel.

Phase-02 sibling to the pension work — six clickable health prototypes across two personas: an EN medical-tourism concierge (itinerary · marketplace) and a TR local health assistant (asistan · aile · ağ).

Efe Arabacı's transportation-design portfolio — a cinematic, spatial hub with a Vehicle-OS work browser and five full case studies (Mahindra · Lotus · Honda · Toyota · Marine). Pure HTML5, no build step.

A software factory — one human orchestrator, role-bound agents, 15 artefacts, 5 approval gates, and a self-improvement loop. This is the v3.0 operator dashboard skin.

A spaced-repetition app for Turkey's 8th-grade high-school entrance exam. Every fact is reduced to a single-sentence atom and never counts as learned until two different question forms confirm it; wrong options are typed misconceptions, and two facts that keep getting confused trigger a short discrimination drill. Works offline; the account exists only so progress survives a lost phone.

A pocket Swiss-army app — compass, altimeter, weather, prayer times, location, speed, qibla and Qur'an translation in one honest dashboard: every value shows its source (sensor · calculation · API). Downloadable APK on GitHub.

A spaced-repetition flashcard PWA for a philosophy doctoral qualifying exam — Leitner boxes, timed exam drills, and a "traps" mode built from my own past mistakes. Turkish UI, offline-first, installable.

A Duolingo-style, bite-sized philosophy learning app — skill path, four exercise types (match · quiz · cloze · argument-ordering), XP & streaks, spaced repetition baked into lessons. Content-agnostic engine; courses are pure JSON.

Bite-sized language learning on the Agora engine — Romanian, Japanese, English, German & Czech for Turkish speakers, plus Turkish for English speakers. Course picker, word-bank translation, diacritic-tolerant typing, hiragana recognition. Six courses, one PWA.

A father-and-son Japan trip guide (Tokyo · Kyoto · Nara · Osaka), frozen into a read-only keepsake — daily journal, photos and star-ratings. Password-gated.
