Skills

I'm a software engineer with 2+ years of experience designing and shipping production full-stack applications on C#/.NET and TypeScript. As Founder and Technical Lead at ByteClub Dev, I build responsive single-page applications backed by RESTful APIs, relational data models with Entity Framework Core, and containerized deployments on Azure and Vercel.

I'm comfortable owning a feature end to end — domain modeling, API design, front-end implementation, code review, and release — and I apply that same rigor as a Technical Support Specialist at Envista Co, where I maintain SLA compliance across a multi-account queue and document technical cases in CRM systems.

I'm a Systems Engineering student at Universidad Fidélitas, expecting to graduate within the next 6 months, bilingual in English and Spanish, and genuinely interested in software craftsmanship — writing code that stays maintainable well after the deadline.

Professional Experience

Technical Support Specialist | Envista Co

(Aug 2025 – Present)
  • Maintain 98%+ SLA compliance across a multi-account queue of hardware, software, and network incidents, working daily in English with distributed stakeholders.
  • Reduced average incident resolution time by ~20% through systematic troubleshooting protocols built with cross-functional teams.
  • Administer client contracts and account data in SAP across 50+ active accounts, and document technical cases and resolutions in CRM systems.

Founder & Technical Lead | ByteClub Dev — Digital Solutions Agency

(2024 – Present)
  • Deliver production full-stack systems for healthcare, home care, and retail clients, building 5+ applications with ASP.NET Core, Next.js, React, Vue 3, SQL Server, MongoDB, and Docker.
  • Design RESTful APIs consumed by fully responsive single-page applications, separating domain, data access, and presentation layers so business rules stay testable and independent of the UI.
  • Model complex business domains from client requirements — service catalogs, tiered pricing rules, contract and client records, and operational reporting — translating ambiguous processes into explicit data models.
  • Own the full SDLC as technical lead, from feature branching and reviewed pull requests to CI/CD pipelines deploying to Azure Container Apps and Vercel.
  • Built WhatsApp Business automation and analytics reporting that cut manual client workflows by roughly 25–30%, running client engagements end to end on projects averaging 3–6 months.
