Sebastián Vansteenkiste

Led a distributed, multicultural team of 10 developers managing the Digital Passport System (DPS), a global component-traceability platform for high-voltage products with data integrations with manufacturing execution systems (MES). Acted as a "hands-on manager" bridging the gap between business strategy and complex technical execution.

• • Technical Stewardship: Navigated a highly complex legacy environment (2,000+ line stored procedures, deep technical debt) by performing technical prospecting and feasibility studies for all new feature requests.

• • Engineering Quality: Drove system reliability through deep code reviews and architectural unblocking, ensuring developers across Spain, India, and Ukraine maintained standards despite significant performance constraints.

• • People Leadership: Served as Line Manager for the Spain-based cohort, leading technical hiring, 1:1s, performance reviews, and conflict resolution with a focus on empathy and professional growth.

• • Process Evolution: Established and documented foundational development workflows and release practices, successfully reducing meeting overhead and improving transparency between Product and Engineering.

• • Strategic Advocacy: Collaborated with global stakeholders to align priorities, advocating for long-term stability and performance improvements over feature-heavy backlogs in a mission-critical production environment.

Architected and developed core modules for a Blazor + Piral micro-frontend application, modernizing a legacy WinForms-over-Citrix system for a major US healthcare provider (HCHB). Acted as a technical anchor and interim lead for "The Terminators" (web scheduler) team in charge of "eliminating Citrix" from the stack.

• • Technical Innovation: provided and documented a method to run the entire application stack locally, enabling end-to-end debugging and drastically reducing resolution time for complex issues.

• • Modernization Strategy: Led the transition from a slow, Citrix-based legacy environment to a high-performance micro-frontend architecture, solving critical user experience bottlenecks like boot-up slowness and lack of SSO.

• • Architectural Advocacy: Navigated a fragmented technical landscape (GraphQL, custom ORMs, and deep SQL logic) to advocate for and implement unified data-access patterns across teams.

• • Collaborative Leadership: Stepped in as interim lead to represent the team in high-level architectural and business discussions, bridging gaps between BAs, designers, and mobile/infrastructure teams.

• • Mentorship: Shared expertise through technical screening and a webinar ("Blazor: Straight to the meat"), fostering technical excellence across the distributed organization.

• • Built serverless Azure Functions integrating third-party financial systems; standardized API interfaces across solutions.

• • Documented existing architecture and business logic, reducing onboarding friction and surfacing improvement areas.
