My Ecosystem

I am the founder and lead developer of Portfolio Analytics, a real-time investment tracking platform built with Node.js, Express, and PostgreSQL that visualizes financial portfolio performance with live data feeds. I also share insights on the future of technology, AI automation, and web development at the Ceciltan Blog.

Beyond client work, these projects demonstrate my ability to architect complete systems end-to-end — from database design and API development to frontend dashboards and deployment pipelines.

Case Studies

Automated Lead Scoring System for Forex
Node.js OpenAI API CRM

Problem: Marketing team was manually processing 500+ leads daily across multiple regions, causing delays and missed high-value prospects.

Solution: Built a Node.js middleware that uses GPT-4 to categorize, score, and prioritize incoming leads based on behavioral signals and demographic data, then auto-routes them to the correct CRM pipeline.

80% less manual work · 35% higher conversions
Real-Time Portfolio Analytics Platform
Node.js PostgreSQL JWT Auth

Problem: Investors lacked a unified dashboard to track multi-asset portfolios with real-time price data and performance metrics.

Solution: Architected a full-stack platform with Express backend, PostgreSQL database, JWT-based role authentication (super_admin, admin, user), and a responsive vanilla JS frontend with live charting.

Live analytics · Automated pipelines · Multi-role access
Multi-Channel Campaign Automation Engine
Make.com n8n GPT-4

Problem: Global marketing campaigns required manual coordination across email, SMS, webinars, and CRM platforms — leading to errors and delays in multi-region rollouts.

Solution: Designed an AI-enhanced automation engine using Make.com and n8n that orchestrates campaign workflows: auto-generates localized email content via GPT-4, schedules Zoom webinars, syncs leads via SendGrid/Twilio, and logs all activity to Google Sheets.
