Client Systems

Client delivery

Enterprise CRM - Sales Pipeline & Performance System

Lead Full-Stack Engineer6-week delivery sprint

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

  • 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.

    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.

What clients say

Anonymized per NDA. Verified project engagements - full context available on request.

Rifki mapped the entire workflow before writing a single line of code. The handoff was clean, the CRM actually fit how our team works, and we stopped reconciling three different spreadsheets on Monday mornings.

Sales Operations Lead — B2B SaaS

Client name withheld per NDA

Async-first, clear blockers, no hand-holding needed. He owned the delivery scope from scope to handoff and flagged the edge cases before they became problems. Exactly what we needed from a contract engineer.

Founder — Ops Tooling Startup

Client name withheld per NDA

The automation cut our manual logging work down significantly. Orders and lead updates now flow through automatically. He set up fallback handling too, so we trust the data now in a way we didn't before.

Operations Manager — E-commerce

Client name withheld per NDA

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.
