Senior🎓
Top SchoolMartin Endler is a Full-Stack Software Engineer with 11 years of hands-on experience building cloud-native web and mobile applications, currently delivering serverless, high-throughput solutions at Merj. As co-founder and former CTO of NFCtron he designed the end-to-end architecture for a market-leading cashless payments platform used at hundreds of events and handling millions of orders, including NFC smart-card integrations and automated SEPA refunds. He combines practical backend expertise (Node.js, TypeScript, Kotlin/Java, PostgreSQL) with devops-for-scale experience (Cloudflare Workers, Docker, Kubernetes, Google Cloud, Terraform). An active open-source contributor, he improved core NFC tooling in the pokusew/nfc-pcsc repo to better support tag types and reader logic — a sign of his systems-level curiosity. Currently finishing a Master's in Cybersecurity after a Bachelor's in AI and Computer Science, he brings both academic rigor and startup grit to production-grade systems.
