Manuel Busquier
Full Stack Engineer
React · TypeScript · Golang · CI/CD
Full Stack Engineer with 4+ years of experience building and maintaining production software. Specialized in React frontend development, with experience developing backend services in Golang, building APIs, managing deployments and improving engineering workflows.
I build and ship across the whole stack.
I care about the product, not just the code: understanding the problem, building a clean solution and keeping it healthy in production. I move between React, Go and .NET comfortably, work well on my own, and like teams that keep their tooling modern.
Product mindset
I think in outcomes and users, and ship features that move the product forward.
End-to-end ownership
From the first line of code to the production release and its monitoring.
React-first, full stack
Strong in React development, with experience building backend services in Go and working with CI/CD pipelines.
Clean engineering
Readable code, sensible architecture and pragmatic, modern tooling.
4+ years building production software.
Hands-on across frontend, backend and the pipelines that deploy them.

I ship and run what I build.
I manage deployments on my own and stay responsible for software once it's in production, automating releases and acting on what the data shows.
Automated deployments
CI/CD with GitHub Actions that builds, tests and ships to production.
Production releases
Coordinating, deploying and validating changes in live environments.
Monitoring & observability
Grafana dashboards to catch regressions before users do.
Error tracking
Sentry for real-time errors, turning signals into fast fixes.
Modern, AI-assisted engineering workflows.
I use modern tooling, including AI, to move faster and keep quality high. It's part of how I work, not the headline.
AI-assisted code reviews
Greptile helps catch issues earlier and keeps review quality high.
Faster day-to-day
AI assists with writing, refactoring and debugging so I ship more.
Pragmatic adoption
I bring in tools that remove friction and skip the ones that don't.
A full-stack toolkit.
