Systems & architecture mindset

Comfortable working beyond standard frameworks (e.g., avoiding typical off-the-shelf solutions like Next.js/Prisma) and contributing to custom architectures, distributed workflows, caching strategies, IPC-based services, and performance-sensitive systems.

Ownership mentality

Proactively identify bottlenecks, suggest improvements, and take responsibility for delivering features from idea to production and monitoring.

High autonomy

Ability to operate independently, handle unclear requirements, and navigate complex or undocumented codebases.
