Hi, I'm Ronny! 👋
I'm a passionate Full-Stack Software Engineer and -Architect with 20+ years of experience.
I currently work full-time, and now and then take on freelance side projects. I build end-to-end web solutions, including websites, web apps, and mobile apps. My strengths lie in joining teams to add momentum, help projects advance, and share experience through consulting, training, speaking engagements, and open-source work.
Open-Source
SOLFees.fyi
SOLFees.fyi lets users enter a Solana wallet address or connect their wallet to see how many transactions they have made and how much they have paid in fees, then share the result.
I built and released it during one of Solana's most difficult periods after the FTX collapse, as a reminder of what makes Solana compelling: low fees, speed, and scalability.
The project received strong community attention on X / Twitter, earned a Solana grant, received user donations, and placed third in Solana RPGF Round 1.
SunriseStake
I was one of six core contributors to Sunrise Stake, a Solana protocol that allowed users to stake SOL while directing staking rewards toward carbon offsets. Through Sunrise Stake, more than 20,000 tonnes of CO2 have been retired on-chain.
Sunrise Stake won two hackathons and received grants from the Solana Foundation.
StakingCentral
StakingCentral is an independent Solana validator explorer and staking interface. It helps users find validators, stake or unstake quickly, and share validators through a Solana Blink so others can stake directly from supported surfaces such as X.
The project was supported by a Superteam grant.
