Automation • Backend • Workflow Systems

I build business systems that reduce manual work and turn messy workflows into structured operations.

My work is focused on lead capture, booking workflows, follow-up automation, approval flows, lightweight CRM systems, and backend logic that ties everything together. I build practical, reusable systems that businesses can actually run day to day.

Projects

This portfolio now includes both my earlier automation work and the stronger backend and systems projects I built more recently. The newer work reflects the direction I am moving toward: reusable systems, safer automation logic, and multi-step operational workflows.

Featured System

Elijahs Client Engine — Reusable Flask Client Delivery System

A reusable backend-first system built to help businesses capture leads, prevent duplicates, trigger alerts, manage bookings, and organize client operations from one structured base.

Problem: Small businesses often manage leads and bookings through scattered forms, manual messages, and inconsistent tracking.
Build: Built a modular Flask system with intake endpoints, validation, duplicate detection, Google Sheets storage, Telegram alerts, client dashboard support, and scalable logic for different business types.
Tools: Flask, Google Sheets, Telegram, Vercel, API routes, structured workflow logic
Result: Created a reusable delivery template that can be adapted for different clients instead of rebuilding each project from zero.

Resort Booking, Availability & Client Dashboard System

A resort-focused implementation of my reusable client engine with booking intake, availability awareness, visual calendar logic, archive handling, and operational controls for the client side.

Problem: Resort bookings and inquiries become difficult to manage when availability, follow-ups, and guest records are handled manually.
Build: Added date-time based conflict detection, mini calendar views, booking controls, archive flows, client-side dashboard sections, and booking-first UX improvements.
Tools: Flask, JavaScript, Google Sheets, calendar logic, Telegram alerts
Result: Turned a simple intake form into a more complete booking operations system with clearer visibility and safer validation.

AI Lead Re-engagement & Slack Approval Workflow

An anonymized automation case study focused on re-engaging older leads, generating AI-assisted follow-up emails, and sending drafts into Slack for approve, reject, or edit review before action is taken.

Problem: Re-engaging old leads manually is slow, inconsistent, and hard to monitor when approvals and edits happen across different tools.
Build: Designed an API-based lead re-engagement workflow with AI drafting, persistent approval drafts, and Slack approve / reject / edit actions as the bridge between automation and human review.
Tools: n8n, CRM API integration, Slack, AI-generated email drafting, webhook routing
Result: Created a clearer review path for outbound follow-ups while keeping the human decision step inside the automation process.

End-to-End Real Estate Lead & Booking Automation System

A multi-step Messenger workflow for property browsing, lead capture, site visit booking, and job application intake.

Problem: Lead handling, site visit booking, and applications were spread across separate manual steps.
Build: Created a Messenger-based flow connected to Google Sheets, Google Calendar, Google Drive, and Gmail.
Tools: Messenger, Google Sheets, Google Calendar, Google Drive, Gmail
Result: Centralized CRM handling and automated multiple business processes from one entry point.

Case Study

Messenger Chat Automation for Lead Qualification

A Messenger flow built to capture customer details, qualify inquiries, and route leads into the business workflow.

Problem: Manual Messenger replies slow down response time and can lead to missed inquiries.
Build: Created a structured chat flow that collects lead details, qualifies users, and routes bookings to admin.
Tools: Messenger, automation logic, Google Sheets workflow
Result: Automated lead qualification and reduced manual admin workload.

Case Study

DTR Automation System Prototype

A modular attendance processing system that reads biometric logs and generates structured daily and monthly reports.

Problem: Manual attendance computation takes time and increases the chance of reporting errors.
Build: Designed a system that extracts biometric logs, computes time metrics, and outputs formatted reports.
Tools: Python, Excel, data processing logic
Result: Standardized attendance reporting and removed manual calculations.

Case Study

J&V Food Products Single-Page Website

A simple business website designed to showcase products and make ordering easier for customers.

Problem: The business needed a clean online presence to display products and support customer ordering.
Build: Built a single-page website with product catalog, cart flow, order form, delivery details, and contact options.
Tools: HTML, CSS, JavaScript, Vercel
Result: Improved product visibility and created a more organized ordering flow.

How my work has evolved

My earlier portfolio leaned more on standalone automations and business websites. The newer projects show a stronger shift toward reusable backend systems, controlled workflows, and operational automation that businesses can keep building on.

1. CaptureForms, chat flows, APIs, and structured intake are used to bring data into one clear workflow.

2. ValidateBackend checks handle required fields, status logic, duplicate detection, and safer processing before anything is saved or triggered.

3. AutomateAlerts, follow-ups, approvals, summaries, and routing connect multiple tools without forcing the team to do repetitive manual work.

4. ReuseThe end goal is not one-off builds, but templates and backend systems that can be adapted across businesses and eventually scaled.

What I Do

Build backend-first workflow systems for leads, bookings, and operations
Create Google Sheets based CRM and tracking systems
Connect platforms using APIs, webhooks, and automation tools
Design approval workflows with human-in-the-loop control
Build client dashboards and simple operational interfaces
Create practical websites that support the workflow behind the business

Best fit projects Lead capture systems, booking workflows, approval flows, admin dashboards, Sheets-based CRM tools, and business process automation.

Tools I work with Flask, Google Sheets, Telegram, Slack, Gmail, Google Calendar, webhooks, APIs, n8n, Make, GoHighLevel, lightweight frontends, GitHub, and Vercel.

Working style I focus on practical systems, safe upgrades, and reusable architecture instead of one-off hacks or overcomplicated builds.
