Walkthrough

Multi-branch operations automation

Quick walkthrough of an automation system I built for a multi-branch service business. Stack is n8n, Google Apps Script, Telegram bot, and OpenAI for parsing. Eight production workflows handling bookings, branch reporting, and staff KPIs.

Commercial proof

CRM, automation, Android AI UX, and multi-surface delivery kept at the center of the portfolio.

  • 1

    Custom CRM replaced 3 separate spreadsheets — pipeline review cycle cut from ~2 days to ~15 minutes.

  • 2

    Inbound order + lead automation eliminated an estimated 60–80 hours/month of manual logging for a multi-branch operator.

  • 3

    AI content automation now covers topic discovery, references, scripts, Docs output, and Sheets approval tracking in one repeatable workflow.

  • 4

    SP2DK/LHP2DK reminders now classify H-7/H-3/H-1/Overdue follow-up with ownership mapping and WhatsApp-ready operations.

  • 5

    Shipped Android AI chat-to-search UX in a live media app — stabilized state sync across the discovery flow.

Client delivery

Enterprise CRM - Sales Pipeline & Performance System

Lead Full-Stack Engineer6-week delivery sprint

Cut the weekly pipeline review cycle from ~2 days of spreadsheet reconciliation to ~15 minutes — single source of truth across sales, ops, and management.

  • Problem

    Pipeline updates and performance reporting were split across 3 separate spreadsheets, making weekly reviews take days and ownership hard to trust.

  • My scope

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

  • Result

    Cut the weekly pipeline review cycle from ~2 days of spreadsheet reconciliation to ~15 minutes — single source of truth across sales, ops, and management.

Inbound Order & Lead Ops Automation

Automation Engineer2-week delivery sprint

Eliminated an estimated 60–80 hours/month of manual data entry across multi-branch operations. Booking + reporting now flow automatically into a single source of truth.

  • Problem

    Inbound orders, bookings, and chat updates were copied manually into spreadsheets across multiple branches, producing inconsistent records, delayed follow-up, and zero operational visibility for management.

  • My scope

    Implemented web-order-to-sheet automation with validation and normalization.

  • Result

    Eliminated an estimated 60–80 hours/month of manual data entry across multi-branch operations. Booking + reporting now flow automatically into a single source of truth.

AI Content Research & Script Automation

AI Automation EngineerCompleted May 2026

Converted manual content research into a repeatable AI-assisted script pipeline with Docs output and Sheets approval tracking.

  • Problem

    Before delivery, each script cycle required manual scanning for current topics, reference validation, source summarization, short-form script drafting, Doc creation, and review-status tracking.

  • My scope

    Mapped the end-to-end content operation: topic discovery, reference collection, summary generation, script drafting, Docs export, and Sheets-based status review.

  • Result

    Converted manual content research into a repeatable AI-assisted script pipeline with Docs output and Sheets approval tracking.

SP2DK & LHP2DK WhatsApp Reminder System

Google Workspace Automation EngineerCompleted Jun 2026

Turned deadline monitoring into a structured reminder workflow with H-7/H-3/H-1/Overdue buckets and WhatsApp-ready follow-up.

  • Problem

    Before delivery, SP2DK/LHP2DK monitoring depended on manual deadline checks, scattered status review, and follow-up visibility that was easy to miss as records moved across owners and sections.

  • My scope

    Mapped the follow-up operation around document type, due date, status, responsible staff/section, and reminder bucket.

  • Result

    Turned deadline monitoring into a structured reminder workflow with H-7/H-3/H-1/Overdue buckets and WhatsApp-ready follow-up.

What clients say

Verified delivery across CRM, automation, and internal tooling projects. Repeat-client context available on call.

Rifki helped us complete our CRM project. He was responsive, understood what we needed even though our team is not technical, and fixed issues quickly. We hope to keep collaborating with him.

  • Product teams that need Android + AI delivery (TFLite, YOLO, on-device CV) alongside their backend or web work

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.
