PRJ-INDEXPRODUCT / SYSTEM CASES10 / Projects

From idea to working product.

I design product architecture, interface, data, infrastructure and delivery as one system — then turn it into something that ships.

Ordovia

Personal daily command center

A multi-platform personal system that brings tasks, notes, habits, planning, projects, rituals and personal knowledge into one daily command center.

HYPOTHESIS01/05

Tasks, notes, rituals, planning, calendar data and the knowledge graph all have different data models. The same account and source of truth also has to remain reliable across web, mobile and desktop.

EVIDENCE02/05

Shared product architecture for tasks, notes, habits, rituals, library and planning

DECISION03/05

Treat the cloud as authoritative and clients as synchronized surfaces

RESULT04/05

Ordovia is a living product shipped on web and Android, with a Windows delivery path and iOS foundation. This case study focuses less on isolated features and more on the architecture that lets the system keep growing.

LEARNING05/05

In multi-module products, domain boundaries matter more than individual screens.

Feedcrumb

RSS and information consumption system

An experimental information-consumption system that normalizes RSS/Atom sources into a calm reading surface.

HYPOTHESIS01/05

XML variants, malformed HTML, full-text versus summary feeds and rendering hundreds of entries require one controlled ingestion pipeline.

EVIDENCE02/05

RSS / Atom ingestion and XML normalization

DECISION03/05

Never expose raw parser output to the UI; normalize into a shared entry model

RESULT04/05

Feedcrumb currently tests ingestion, reading, bookmarks and PWA behavior as one experimental product flow.

LEARNING05/05

In content products, normalization can matter more than the interface.

SaaS · Reading discovery

Bookcrumb

Personal reading discovery and route system

A recommendation product that builds personal reading routes from mood, interests, pace and reading history.

HYPOTHESIS01/05

Mood, theme, pace, profile and history signals had to become one recommendation context that remains consistent across routes, notes and membership state.

EVIDENCE02/05

Mood / theme / pace context model

DECISION03/05

Model recommendation as route context rather than a single-book score

RESULT04/05

Bookcrumb is live with discovery, routes, notes, memory and paid membership combined into one reading experience.

LEARNING05/05

In recommendation products, context design matters more than the model call.

Lumoria

Contextual travel planning system

A travel product that starts from where the user actually stays and combines interests, time, mobility and weather context.

HYPOTHESIS01/05

Several variables had to become one route decision without exposing a complex planning dashboard to the user.

EVIDENCE02/05

Location / hotel-based route origin

DECISION03/05

Build route context from the real origin rather than the city center

RESULT04/05

Lumoria is live with contextual routes, discovery memory and weather awareness combined into one travel flow.

In planning products, good defaults are more valuable than more options.

Good Move

Meal + movement planning system

An experimental system that generates a two-week personal plan from goals, food preferences, preparation time, movement preferences and equipment.

HYPOTHESIS01/05

Many constraints had to become an actionable two-week plan while keeping the active plan available through connectivity problems.

EVIDENCE02/05

Onboarding and profile context

DECISION03/05

Bind meals and movement to one constraint context instead of separate planners

RESULT04/05

Good Move tests personalization, constraint-based planning and weekly execution as one experimental product.

LEARNING05/05

Personalization is less about adding options and more about resolving constraints in the right order.

Transformation cases

Not simply repainting an existing product, but reading the problem and turning it into a stronger product and sales surface.

Secil Studio

Independent micro-product studio

A single brand and discovery layer for independent micro-apps focused on small everyday decision problems.

BEFORE / PROBLEM

The products needed to remain discoverable without competing with one another, route cleanly to independent surfaces and keep the studio brand from overpowering the tools.

AFTER / SOLUTION

I positioned the studio as a discovery and routing layer rather than a heavy account dashboard, grouping independent tools under one information architecture.

HYPOTHESIS01/05

The products needed to remain discoverable without competing with one another, route cleanly to independent surfaces and keep the studio brand from overpowering the tools.

EVIDENCE02/05

Shared discovery architecture for multiple micro-products

DECISION03/05

Keep the studio shell simpler than the products it presents

RESULT04/05

Secil Studio is live as a micro-product umbrella that keeps several applications visible and accessible under one brand.

LEARNING05/05

In micro-products, brand architecture can create more leverage than feature volume.

PRJ-07Live

Outfit Matcher

Focused wardrobe decision tool

A small focused decision tool for visually testing outfit combinations from a user's own wardrobe.

BEFORE / PROBLEM

The outfit state created from item selection had to stay understandable without pushing the user into a complex editing surface.

AFTER / SOLUTION

The interaction is kept to a short chain: wardrobe → selection → outfit state → visual combination → change / retry.

HYPOTHESIS01/05

The outfit state created from item selection had to stay understandable without pushing the user into a complex editing surface.

EVIDENCE02/05

Wardrobe item selection

DECISION03/05

Avoid growing the product with unnecessary account, feed or social layers

RESULT04/05

Outfit Matcher is a live Secil Studio micro-product focused on one problem.

LEARNING05/05

For micro-tools, a clear boundary is a product advantage, not a limitation.

Chaotic Brain Studio

Content + tools + digital product platform

A platform that combines guides, glossary content, digital products and interactive micro-tools in one content system.

HYPOTHESIS01/05

Evergreen SEO content, glossary entries, micro-tools and digital products had to coexist under one navigation and content model.

EVIDENCE02/05

Guide and glossary content architecture

DECISION03/05

Connect content and tools under one information architecture instead of separate sites

RESULT04/05

Chaotic Brain Studio is live with content, glossary, digital products and micro-tools published under one product platform.

LEARNING05/05

On a content platform, tools are not just features; they are also part of distribution.

Kurmaca.ink

Fiction writing and narrative logic workspace

An editorial product that combines long-form fiction writing with chapters and scenes, character knowledge, clues, timeline, narrative logic and continuity controls in one workspace.

HYPOTHESIS01/05

Narrative state split across editors, notes and spreadsheets breaks writing focus, while scene edits on Web/PWA also need a safe path through cloud synchronization failures.

EVIDENCE02/05

Chapter / scene structure and focused long-form editor

DECISION03/05

Keep the author and manuscript central instead of making AI chat the product center

RESULT04/05

Kurmaca.ink is live as a Web/PWA product combining the writing editor, structured narrative logic and Supabase-backed project continuity in one workspace; its crash-recovery layer is also developed behind explicit automated verification gates.

LEARNING05/05

In a writing product, the critical UX measure is not feature count but how rarely the author is pulled away from the manuscript.

Rail

Edge-first fast-capture workspace for Windows

A Windows product focused on capturing notes, tasks and decisions from the edge of the screen without breaking the main workflow.

HYPOTHESIS01/05

Fast capture, structured notes/tasks and the commercial model had to coexist without making the Windows experience heavy, while paid plans needed to be separated by real product differences.

EVIDENCE02/05

Windows-first fast capture and Command Center product model

DECISION03/05

Keep an edge-first fast-access model instead of growing into a general-purpose desktop dashboard

RESULT04/05

Rail's rail.ahmetcanal.com sales surface, pricing and Paddle plan configuration are in place, while the Windows product is explicitly kept in pre-release state in the source. This case focuses on product boundaries and commercial architecture.

LEARNING05/05

In a desktop productivity product, speed is a product boundary that comes before feature count.
