Writing and rereading ask for different kinds of attention. A long draft also needs a way to keep your place.

Desktop and mobile checks confirmed paragraph navigation and exact text preservation when returning to editing. The guest trial is not saved.

Keep the illustration in place. Hide the phrase and comparison to recall it from the scene, then reveal the words to check.
Desktop and mobile checks confirmed hide, recall and reveal. Changing the language restores the phrase, with the same scene as its reference.
A place for the next thought.
A web-based writing space for turning thoughts into documents. Search and an editor sit within the same workspace.
The central design question is how to keep the act of writing in focus while making saved documents easy to find. The public interface brings account access, search and the document workspace together.
My work at OmusBridge spans product planning, MVP exploration and web development. These interfaces are being refined with Codex.

Text résumé ↗As a TPM (Technical Project Manager) who can work across both technology and business, I have driven a wide range of projects from management to hands-on development, covering web development, project management, business operations, and organization management.
At university, I studied media and regional revitalization, then earned the Fundamental Information Technology Engineer certification to build a career in globally applicable IT. At TIS Inc., I worked as an SAP ERP consultant and experienced the full delivery cycle from requirements definition and design to development, testing, and operations.
After that, I moved closer to product creation through web development at Step IT Solution Co., Ltd. and through self-employed work. As a self-employed professional, I also worked outside pure engineering, including doujin event operations, writing, and ICT instruction.
I joined HIKKY Co., Ltd. as the company's first dedicated engineer in the web frontend domain. I built frontend architecture used across the company, created coding guidelines, helped launch the team, and handled management responsibilities. From 2024, I led the Web-related Technology Development Department. In October 2025, after the results of an event business I had personally driven in Sapporo were recognized, I became Head of the Project Management Department. Due to career planning based in Sapporo and changes in life stage, I left the company in September 2026.
I am currently building a career as a TPM x FDE (Forward Deployed Engineer) with Codex as an AI partner.
Project management, planning, accounting, business-unit and company-level management
As Head of the Project Management Department, I worked across pre-sales planning, requirements organization, progress management, delivery, business planning, and organization management. Using my technical understanding from web development, I connected planning, sales, development, and production teams and translated projects into executable plans.
Across multiple projects, I contributed not only to delivery but also to scaling upsell and cross-sell opportunities. I also worked beyond field-level execution, including cost and revenue management proposals for executive members, execution of improvement measures, and organization improvement planning.

I handled a wide range of responsibilities as PM for an event where more than 700 people gathered.
