Juan C.

Available for one-off, short projects only at the moment. Founders and executives hire me when they need someone they can trust with the complex, the sensitive, and the behind-the-scenes. I design and implement backend systems for small teams: onboarding workflows, HR tracking tools, Slack integrations, and documentation hubs, so operations run without manual overhead. My focus is structured, maintainable systems using tools your team already has. Nothing bloated, nothing over-engineered. What I build: - Slack API integrations: slash commands, webhooks, approval workflows, bot logic - Google Sheets: ARRAYFORMULA, QUERY, dynamic automation logic - Make: multi-step workflow automation and system integrations - Webhook and API connections between platforms - HR systems: PTO tracking, onboarding workflows, personnel documentation - Process documentation and SOP libraries When the work goes beyond systems, I handle what sits underneath: legal and administrative coordination, founder executive support, visa and compliance processes, cross-functional coordination across legal, finance, and operations. I've built HR automation systems that reduced onboarding admin time by over 80% and cut recurring tool costs by more than 98%. I've also managed active legal cases from start to finish, handled multi-jurisdiction documentation, and coordinated across legal, finance, and operations simultaneously. The work I take on tends to be the kind that doesn't fit a single job description. Also bilingual (EN/ES), useful for teams operating across European and US markets or with Spanish-language documentation needs. Based in Spain (CET). Available to European and US-based teams. Best fit: Founders who need reliable operations infrastructure, and can use someone who handles both the systems and what sits behind them.
