The Beginning (2018)

I started as a freelance web developer on Upwork and Fiverr. My first project paid $50 — a WordPress landing page. I was thrilled.

At this point, my skills were basic:

▸HTML/CSS

▸Basic JavaScript

▸WordPress

▸Bootstrap

Going Full Stack (2019-2020)

I realized freelancing had a ceiling. To grow, I needed deeper skills. I invested time in:

▸React.js — Changed everything for me

▸Node.js — Backend became accessible

▸MongoDB — NoSQL felt natural

▸REST APIs — Connecting frontend to backend

By 2020, I had completed 50+ freelance projects and built a solid reputation.

Joining Relymer Group (2021)

The biggest turning point. I joined as a Frontend Engineer and within months moved to Full Stack. The key difference from freelancing:

▸Working with a team

▸Code reviews and standards

▸CI/CD pipelines

▸Production-scale applications

Discovering Web3 (2022)

Blockchain fascinated me. I started learning:

▸Solidity smart contracts

▸Web3.js and Ethers.js

▸DApp architecture

▸Token economics

My first DApp was a simple staking platform. It was buggy, but it worked. That moment hooked me.

Leading Teams (2022-2024)

I became Head of Development at Relymer Group, managing multiple teams:

▸8+ developers across projects

▸Sprint planning and code reviews

▸Architecture decisions

▸Client communication

Senior Blockchain & AI Engineer (2025-Present)

Today, I specialize in:

▸Smart contract development and auditing

▸AI-powered automation with N8N

▸Full-stack DApp development

▸Team leadership and mentoring

Key Lessons

1.Never stop learning — Technology changes fast

2.Build in public — Share your work, it opens doors

3.Quality over quantity — One great project beats ten mediocre ones

4.Invest in people — Your network is your net worth

5.Embrace AI — It's not replacing us, it's empowering us

The journey from $50 freelance gigs to Senior Engineer wasn't linear. But every project, every failure, and every late night contributed to where I am today.
