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.
