What database powers some of the world's largest applications? PostgreSQL. In this video I break down what PostgreSQL is, why it is one of the most trusted databases in the world, and why it is the database I chose for my back-end stack.
We cover:
What a relational database actually is
What makes PostgreSQL different from other databases
ACID compliance and why it matters for your data
Advanced data types — JSON, UUID, arrays and more
Performance and query optimization
PostgreSQL vs MySQL — which should you choose
Why Directus works best with PostgreSQL
How PostgreSQL fits into my back-end stack
My Back-End Stack:
🗄️ Directus — Headless CMS
🐘 PostgreSQL — Relational database
⚡ Redis — Caching layer
🚀 Coolify — Self-hosted PaaS
🖥️ VPS — Cloud hosting
⚠️ This channel is highly opinionated — I share the tools I use and how I use them. Stay with me through this series and we will explore how they all work together.

Zappy: Building a Real-Time Workflow Layer for WhatsApp-Based Businesses
Zappy is a mobile first shared WhatsApp inbox for small businesses, designed to turn chaotic customer messaging into structured team workflows.
The core problem is not messaging, but coordination. As small teams grow, conversations become fragmented, messages are missed, and there is no clear ownership or system of work.
I designed Zappy as a real time, multi tenant communication system where every business operates in an isolated workspace, and every conversation is structured, trackable, and assignable across team members.
The system is built with a contract first architecture using OpenAPI and shared types, ensuring the backend and mobile app stay fully in sync as the product scales.
Real time updates are handled through Socket.IO, with fallback polling for reliability across environments.
On top of this communication layer, AI is embedded directly into workflow moments, not as a separate tool. It assists with reply suggestions, conversation summaries, tone rewriting, sentiment detection, and off hours responses, all aimed at reducing cognitive load and response time for small teams.
Zappy is ultimately a workflow layer for WhatsApp based businesses, focused on structure, speed, and clarity in customer communication.
Building products is what excites me most.
I’m a backend-focused Full Stack Engineer working on scalable APIs, AI-powered workflows, automation systems, and modern SaaS products using Node.js, TypeScript, React, PostgreSQL, Redis, and AWS.
Recently, I’ve been building:
• DeepLock — focus & productivity platform for Android + Chrome
• AI-powered automation workflows
• Event-driven backend systems
• SaaS tools solving real-world workflow problems
• Job automation and AI agent systems
I enjoy fast-moving startup environments where ownership, execution, and product thinking matter as much as coding.
Currently open to:
• Full Stack Development opportunities
• Backend Engineering roles
• AI-native product engineering
• Startup and remote opportunities
Always excited to connect with builders, founders, and teams working on meaningful products.
Introducing Job Board Hub, a full-stack application built with the MERN stack to explore remote job opportunities across different areas such as technology, design, marketing, and more.
The main idea behind the app is to help users find job opportunities and quickly understand whether a position fits their profile.
One of the main features is AI Job Summary, an artificial intelligence integration that generates summaries of long job descriptions. Many job posts often include lengthy text, mixed requirements, and repetitive information, so the goal was to improve the user experience and make reading faster and clearer.
Beyond the visible feature, this project also allowed me to work on important backend decisions:
- AI integration through an AI Gateway
- The possibility to switch or combine models in the future
- Rate limiting to prevent abuse and control token usage
- Streaming responses to improve the perception of speed
- Clean backend architecture within a MERN app
- Organization of remote jobs by categories
The focus was not just to “add AI,” but to integrate it in a more thoughtful way: considering costs, user experience, scalability, and system control.
Job Board Hub is a simple app in concept, but it helped me demonstrate how an AI feature can provide real value when supported by good backend decisions.
I’m very happy with this project because it combines product, backend, and artificial intelligence into a useful and easy-to-understand experience.
