Extensive personal project experience in Go, demonstrating strong backend and systems-level programming capabilities.

Cultural & Operational Fit

Cultural Fit Analysis

The candidate's projects are almost exclusively Go-focused, indicating a strong preference and expertise in backend/systems development. While the target role is 'Frontend Developer' and the current role is also 'Frontend Developer', the personal projects do not align well with typical frontend skill sets (e.g., JavaScript frameworks, modern CSS, build tools). This suggests a potential mismatch in primary interest and the target role's core requirements, or a significant career pivot not reflected in personal work. The single project 'diffty' lists HTML and CSS, but the primary language is Go, suggesting a minimal frontend component.
