I write screenplays, treatments, series bibles, and documentary scripts, and I design branching game narratives where player choices truly matter. My background in psychology and cognitive science helps me build character‑driven stories with clear structure and a tight integration between narrative and gameplay.
Games & Interactive
– Lead Writer & Narrative Designer on NEM: Recall (visual novel, release Feb 2026): characters, worldbuilding, story outlines, and serialized episode scripts.
– Writer & Narrative Designer for a fantasy visual novel: designed characters and plot, wrote dialogues, and implemented them in Unity Dialogue System in collaboration with art and game design teams.
– Freelance Narrative Designer on multiple titles: plot for a VR space‑exploration demo, worldbuilding and lore for an Arabian‑mythology ARPG, and worldbuilding for a fantasy TCG.
Screenwriting & Documentary
– Screenplays, treatments, and series bibles for films and TV concepts.
– Documentary and YouTube scripts, combining narrative drive with clear exposition.
– Writer for Witcher School LARP: designed characters and backstories for an international live‑action game.
How I work
– Collaboration: used to working with directors, producers, and art/game design teams using Jira, ClickUp, Miro, and Git.
– Visual storytelling: I favor “show, don’t tell”, using actions, images, and visual metaphors rather than exposition.
– Structure: I treat stories as complex systems – planned for clarity and consistency across long‑form narratives.
Training
– Story Masterclass at StoryAcademy (screenwriting for film & TV: feature script, series bible, pilot).
– Storylab.Pro one‑year screenwriting course + writers’ room practice on a series bible and pilot.
– Narrative Designer course at SKVOT (characters, worldbuilding, dialogues, GDD).

It has been 14 years since I started here in oDesk, which is now Upwork.
I have acquired the necessary experience needed in the online market and business ventures.
I have improved my 5 work policy ever since I started in this line of work.
These would be:
1) To always ensure the Client gets quality work.
2) To always submit the Client's work on or before the deadline.
3) To always have a stable and open connection with the Client.
4) To always inform the Client of any emergencies or problems with the work several days prior to the deadline so as not to hinder the progress.
5) To always ask questions as long as it is necessary pertaining to the Client's work.
My record and rating may not be a 5-star brand, but the quality of the work I put out is always good and near perfection. I hope that anyone who is interested in hiring me sometime in the future will get what they really want and how they want it.
