Marvin Gorecki

• Drive technical and architectural decisions across frontend applications, mentor four Frontend Engineers through individual development plans and code reviews, and conduct technical interviews for frontend hires.
• Shipped LLM-backed solutions and led the team's adoption of sandboxed LLM environments, establishing how AI tooling is run safely in day-to-day development.
• Led accessibility improvements across four single-page applications targeting WCAG 2.2 AA, resolving recurring accessibility issues and establishing accessible implementation patterns.
• Initiated a reusable, accessible design system, now around 50 components consumed by 5+ applications, giving product teams shared UI patterns and reducing duplicated frontend work across the portfolio.
• Improved Core Web Vitals across multiple applications and optimized CI pipelines, addressing bottlenecks in both the product and the developer feedback loop.
• Automated the detection of vulnerabilities introduced through transitive dependencies, strengthening frontend software-supply-chain security.

• Built product features across React and TypeScript applications and contributed to frontend architectural decisions.
• Developed a reusable design system to standardize UI implementation and improve consistency across the product.
• Streamlined deployment workflows to reduce friction for frontend developers.
• Led internal knowledge-sharing sessions on advanced TypeScript concepts and type-safe application design.

• Developed security-critical frontend functionality for Bdrive, an end-to-end encrypted file storage and sharing platform.
• Implemented WebAssembly-based encryption and decryption fallbacks to enable end-to-end encryption in browsers where Web Crypto API support was still limited.
• Designed a user-driven entropy collection mechanism for cryptographic key generation.
• Implemented the frontend integration with a custom identity provider and authentication service.

• Developed core product functionality for Bdrive, a secure end-to-end encrypted file sharing platform.
• Led the development of a reusable design system for consistent product UI implementation.
• Designed upload and download visualizations that made encrypted file-transfer states understandable to users.

• Built internal data-labeling tools used to create curated training datasets for machine-learning models.

• Designed and built an automated data ingestion pipeline for scraping, aggregating, and normalizing heterogeneous public datasets.
• Built analytical interfaces combining multiple data sources to support the exploration of company networks.
