Full-stack developer · Belgrade, Serbia
I'm Denis Ćorić, a senior engineer at G-Research focused on building reliable trading and data platforms. A decade of experience across JavaScript, TypeScript, Python, and cloud-native stacks helps me lead projects end-to-end—from product discovery to production observability.
About
My craft sits at the intersection of product thinking and technical leadership. Whether it's architecting React/Next.js frontends, scaling Node.js services, or automation pipelines for cloud infrastructure, I aim to shorten the loop between idea and measurable value.
I care deeply about developer experience and code quality. Recent work includes leading greenfield initiatives, elevating design systems, and mentoring teams on modern TypeScript patterns, testing, and observability practices.
Capabilities
Design systems, data visualisation, and performance budgets for enterprise web apps.
Event-driven services, authentication flows, and resilient serverless architectures.
Mentorship, code review, testing strategy, and delivery workflows that scale teams.
Selected Work
A glimpse into open-source experiments and client-facing platforms. Each project ties product outcomes to a reliable delivery workflow.
A Node.js service that enriches requests with GeoIP data, Cloudflare headers, and local MaxMind fallbacks—deployed as a drop-in API for edge workloads.
Lightweight API that returns precise longitude, latitude, and timezone details from IP addresses to power location-aware experiences.
Contributions to Apache YuniKorn's Web UI, modernising cluster visualisations and improving the developer experience for scheduling insights.
A Grafana plugin that provides an incremental trace viewer for efficient analysis of distributed tracing data, enhancing observability workflows for complex systems.
A FINOS project that acts as an intermediary between developers and Git remote endpoints, enforcing customizable push protections and compliance policies.
A news aggregation platform that retrieves breaking news headlines and enables article search across various news sources and blogs worldwide.
What drives me
Product work thrives when research, design, and engineering sit around the same table. I bridge these disciplines—asking better questions, mapping technical risks, and ensuring the release roadmap stays aligned with customer value.
