About
Background
I'm Mehmet Berke Karadayi, a Software Engineer at Coinbase and an Electrical Engineering graduate from the University of British Columbia, focused on building reliable product systems across frontend, full-stack, real-time, and AI-assisted workflows.
My work spans React, TypeScript, GraphQL/Relay, WebSockets, backend services, and LLM-powered tooling. I'm especially interested in applying AI to improve engineering workflows, developer productivity, and product experiences.
I enjoy solving ambiguous technical problems and turning them into polished, maintainable software. I value ownership, collaboration, and engineering craftsmanship across software engineering, AI, fintech, and product impact.

Software Engineer
June 2025 - Present
Building production-grade frontend systems across trading workflows, real-time product interfaces, reliability tooling, and AI-assisted engineering automation.
- Owned software architecture for trading workflows from MVP through production, building React, TypeScript, and GraphQL/Relay systems.
- Built real-time product systems with WebSockets, Redux, and GraphQL, with a focus on scalable state management and maintainable UI architecture.
- Developed AI-assisted tooling for release automation, on-call triage, debugging, and incident-response workflows.
- Collaborated cross-functionally to ship iterative trading releases with rollout safety, telemetry, and regression coverage tuned for production readiness.
Full Stack Developer Co-op
Jan 2024 - Apr 2024
Built scalable full-stack systems for sustainability analytics workflows and user-facing product experiences across a Chrome extension and web platform.
- Developed React and TypeScript Chrome extension experiences for Digital Scope, shipped as a production user-facing product.
- Designed Django REST Framework and PostgreSQL APIs for high-volume data ingestion and sustainability analytics workflows.
- Built AWS-backed infrastructure using RDS, SQS, Secrets Manager, and S3 to support platform scale.
- Improved frontend performance through React component optimization and close collaboration with design.
Software Development Co-op
May 2023 - Dec 2023
Built desktop engineering workflow tools for complex, data-heavy interfaces used by geotechnical engineering teams.
- Built React, Electron.js, and Fluent UI desktop application experiences for engineering workflow software handling large datasets.
- Used Redux and React Hooks for scalable state management across complex data visualization views.
- Integrated frontend components with backend Node.js services for data processing workflows.
- Added Jest and React Testing Library coverage for reliable UI behavior across the application.
Projects
Featured work
Selected technical projects across AI product engineering, full-stack systems, and crypto interfaces.
AI Product Engineering
ResumeFit Agent
LLM-powered resume-to-role fit evaluator built with Next.js and TypeScript. Compares resume and job-description signals, returns structured fit assessments, and uses schema validation, timeout handling, and heuristic fallbacks for reliability.
Full-Stack · Simulation
Energy Simulation Tool
Full-stack renewable energy simulation platform for solar, wind, and hydro analysis. Built real-time calculation workflows, automated PDF exports, and an AI-assisted technical layer for interpreting simulation outputs.
Crypto · Product Interface
Web3 Portfolio Dashboard
Wallet-connected portfolio dashboard for exploring token holdings on Base. Built with Next.js, OnchainKit, and Alchemy SDK, with sortable tables, pagination, skeleton loading, and dark-mode-first data views.
