Professional Summary

Full stack developer with four years of experience in TypeScript, React, Next.js, and NestJS. Currently at Enterstep, building a B2B digital onboarding platform for regulated financial institutions. Previously built internal management panels for Minecraft content studios: production tracking, finance modules, and per-team access control. I work with automated testing and continuous integration as part of the process, from data modeling with Prisma and PostgreSQL through to deployment with Docker and Kubernetes.

Current role

Temporary contractSantiago, Chile (hybrid)June 2026 – Present

›I develop and maintain a B2B digital onboarding platform for regulated financial institutions.
›I work end to end on the product: the client onboarding flow, the APIs (REST and GraphQL), the data model, and cloud deployment.
›Small team of four developers including the CTO, plus one QA. There is not much room to leave decisions half finished, so I work with a focus on architecture, code quality, and user experience.

Freelance · Internal panels for Minecraft studios

~4 years

Self-employedRemote (international clients)April 2022 – Present

›Built internal panels for four Minecraft content studios (Spring Craft, Rytale, MiraclesMC, and currently Spring Games). Almost always the same underlying problem: track production, reconcile studio finances, and coordinate the team in one place.
›Built the kanban board for the publishing pipeline, with review, certification, and release states, per-project detail, and a team filter that persists as you move between screens.
›Implemented the finance module: partner earnings with a deduction percentage configured per studio, invoices, staff payments, and the monthly billing close.
›Solved data isolation per team with role-based access control, plus internal chat and analytics views for income and expenses with report export.
›Owned the full cycle with no middlemen: requirements with the client, development, deployment on my own VPS (Ubuntu, custom domain, HTTPS with SSL), and ongoing support.
›Two of those studios came back years later for a second version of their panel. At Spring Games I rebuilt the backend from Express to NestJS and kept the frontend on Next.js, preserving the original functionality on a better organized base.

Projects

Products I worked on as a developer. Code is owned by each company; links go to the live product, and internal projects have no public access.

Studio Finance Hub

Full Stack Developer (freelance) · Spring Games

Second version of the finance and content management panel for a Minecraft Marketplace content producer. Internal use, not publicly accessible.

›Rebuilt on NestJS and Fastify the backend the v1 had in Express, keeping the Next.js frontend and the functionality the client already relied on.
›Set the repo up as a monorepo: the API, the web panel, and an in-house 3D skin rendering package, with Prisma on PostgreSQL, Redis, and Docker Compose.
›Building the drag and drop kanban pipeline, the partner earnings module with a configurable deduction, and the multi-tenant filtering by team.

Languages

I study English with a technical focus: documentation, code, and meetings. I read and write it without trouble day to day; what I'm working on is speaking it fluently. Across four years of remote work with international clients I haven't hit communication or delivery problems, and I want to get as comfortable in a meeting as I am in a pull request.
