Denis Ćorić

Full-stack engineer building resilient web and cloud products with TypeScript, React, and thoughtful developer experience. I currently craft open-source tooling at G-Research OSS, partner with product teams across Europe, and occasionally swap the keyboard for a 7-iron or Blender session.

Snapshot

• 🌍 Based in Belgrade, collaborating remotely across EU/UK time zones
• 🧠 10+ years of experience spanning frontend platforms, API design, and DevOps automation
• 🧑‍🤝‍🧑 Leadership focus on mentoring, design systems, testing strategies, and observability culture
• 📬 Always open to OSS collaborations, DX initiatives, and data-heavy product work

What I'm focused on

1. Frontend platforms – Next.js/React architectures, performance budgets, data visualisation, design systems, Storybook-driven handoffs.
2. Backend & data – Event-driven Node.js services, GraphQL/REST APIs, PostgreSQL, Redis, serverless runtimes, and security-first workflows.
3. DevEx & platform enablement – CI/CD, policy automation, traceability, and the tooling that helps teams ship faster without sacrificing quality.
