    • Wrote the BRD, SRS, and user stories with acceptance criteria, and modelled core flows (clinic onboarding, payments, CRUD operations) in BPMN and UML activity diagrams.
    • Designed the system architecture, chose the tech stack, and designed the database schema, splitting clinic and admin data into two separate databases.

    Reops

    Project Manager, Business Analyst, Software Engineer

    Saudi Arabia, Remote

    • Ran a gap analysis of the existing WordPress + LMS-extension setup, compared build vs buy, and built the business case for a custom SaaS LMS, then defined its scope, OKRs, and KPIs (course completion, active trainees).
    • Re-engineered the WordPress and LMS-extension solution into a custom SaaS LMS that is cheaper to run and more scalable, and integrated the Vimeo REST API for in-platform video streaming.
    • Owned the LMS backlog and roadmap, modelled key flows (enrollment, course completion, payments, course CRUD) in BPMN and use case diagrams, and ran UAT.
    • Built Reops Studio, an internal AI-powered platform built with Claude Code, to manage client projects, generate scripts and shooting sheets, and track teams, cutting production time from 3 months to 1 and reducing editing costs.
    • Directed daily operations of the SOP video production line for F&B clients: shooting schedules, equipment procurement, and coordination of videographers and editors; primary stakeholder liaison from onboarding to handoff.
    • Documented and standardised the production line from shooting schedule to editing handoff so all teams worked from one process.
    • Built the Reops landing page in React and deployed it on Vercel.

    • Elicited functional and non-functional requirements, mapped as-is and to-be processes, found bottlenecks through root cause analysis, and turned them into scopes and prioritised backlogs.
    • Defined user flows in UML activity diagrams as the basis for the designer's wireframes and prototypes, and validated them with clients before development.
    • Streamlined delivery tracking with ClickUp, Trello, and ClickUp Automations, and kept stakeholders aligned with status reports.
    • Designed, coded, and deployed client landing pages with WordPress, HTML/CSS, and React, including hosting, domain, and SSL setup.
