  • My scope

    Mapped sales stages, reporting rules, and operator roles before touching schema or UI.

  • Result

    Gave the team one place to review pipeline movement, ownership, and performance snapshots without spreadsheet reconciliation.

Media Android App - AI Chat + Search UX

Android AI UX Engineer3-week delivery sprint

Made the AI-assisted discovery flow clearer and more reliable from chat prompt to search result.

  • Problem

    Users lacked a clear transition from AI chat prompts to meaningful search actions, and state sync issues reduced UX reliability.

  • My scope

    Worked inside the existing WebView-based AI entry path so the feature fit the live app architecture.

  • Result

    Made the AI-assisted discovery flow clearer and more reliable from chat prompt to search result.

  • Problem

    Separate repositories for related surfaces caused dependency drift and slowed coordinated releases.

  • My scope

    Structured the repository with npm workspaces and clearer package boundaries.

  • Result

    Reduced release friction and dependency drift across the platform.

  • npm workspaces

Why teams bring me in

  • Shipped client systems across CRM, automation, Android AI UX, and platform delivery.
  • Worked directly with stakeholders on scope, delivery order, and handoff context.
  • NDA-safe proof stays factual: live environments, shipped systems, and clear ownership.

Good fit

  • Teams losing time to spreadsheet sprawl, manual routing, or fragmented internal workflows
  • Founders or operators who need a reliable engineer to own a scoped delivery sprint
  • Product teams that need Android + AI support alongside backend or web implementation

Working style

  • Scopes are broken into milestones with clear delivery order and acceptance criteria.
  • I work comfortably inside existing products, not just greenfield builds.
  • Handoff quality matters as much as implementation speed.
