My Tech Stack

Over the years, my tech stack has evolved based on what I actually use to build real things. I don't chase trends or overcomplicate. If a tool gets the job done efficiently, I stick with it.

This is my current, battle-tested stack—optimized for speed, simplicity, and execution.

Philosophy

I'm not a tool collector. I'm a product builder.

Every tool I use exists for one reason:
To help me ship iOS products with speed, precision, and zero bloat.

iOS Development (My Core Focus)

Swift + SwiftUI

This is home base.
Swift is fast, modern, and native. SwiftUI gives me velocity, modularity, and total control over the user experience.
It's the tech I love—and the one I build mastery in.

Cross-Platform – React Native (only when required)

I don't use cross-platform for my own products.
If a client or project needs or requires it, I'll build with React Native. It's fast, effective, and gets the job done.

Backend & Serverless

Firebase – My Primary Backend

For most of my apps, Firebase is the move.
Serverless, scalable, and tight with mobile—perfect for MVPs and even full-scale products.
Auth, Firestore, Functions, Analytics—done.

Front-End Development

React + Next.js + TypeScript/JavaScript

Used for admin dashboards, landing pages, or companion web apps.
Next.js is actually full-stack, clean, fast, and production-ready.
Deployed on Vercel for frictionless builds and CDN-level speed.

AI & Machine Learning

iOS-Native First

When it comes to AI, I prefer staying local and private:

Core ML
Create ML
Natural Language
VisionKit

I use these to embed AI directly into my apps—no server calls, no third-party data leaks.

Cloud AI – When Necessary

If a use case demands it, I'll bring in:

Gemini APIs for LLMs
RAG setups with LangChain, Pinecone, and vector DBs

But only when it's worth it.

Developer Toolkit

Xcode – My main workspace for Swift and SwiftUI
Cursor – AI-enhanced coding and debugging
Sketch – iOS app design and prototyping
SF Symbols – Clean iOS-native iconography
App Store Connect – App distribution and analytics
TestFlight – Beta testing and feedback collection
Xcode Cloud – CI/CD for iOS apps

Nothing fancy. Everything sharp.

Final Words

You don't need a complicated stack to build great things. You need a sharp one.

This setup helps me stay focused, consistent, and in full control of the products I create.
