Francisco Llantada
Robust systems that adapt when everything else changes.
Senior full-stack engineer specialized in building architectures that separate what changes from what stays. Clean domain boundaries, abstract integrations, and codebases that scale with your product.
What I deliver
Consulting
I analyze how your team works, identify where AI agents can accelerate delivery, and implement the tooling. More output, higher quality, less overhead.
AI-powered systems
Multi-agent orchestration, workflow automation, intelligent assistants. Production-ready and built to deliver real business value.
Backend architecture
Scalable systems designed to grow with your product. Add features, onboard developers, change direction — the architecture supports it.
Frontend & product
Performant interfaces, real-time dashboards, mobile applications. 520+ production PRs across enterprise projects.
Third-party integrations
Payments, communications, external APIs. Connected cleanly so you can switch providers when the business needs it.
Engineering principles
Keep it simple
If a solution is hard to explain, it's probably wrong. Simple systems are easier to debug, scale, and hand over.
Single responsibility
Each piece of the system does one thing well. When something needs to change, you know exactly where to go — and nothing else breaks.
Clear boundaries
Each area of the business owns its own code and rules. Orders, payments, and shipping each evolve at their own pace — independently, without breaking each other.
Organized by purpose
Code is grouped by the problem it solves, not by its technical role. Everything a feature needs lives together — so changes are local and deployments are safe.
Independence over reuse
Reusing code sounds efficient, but it creates hidden connections. I prefer independent pieces that can evolve separately — even if they look similar at first.
Nothing extra
Every line of code exists for a reason. If it's not needed now, it doesn't ship — because unused code is future confusion.
Self-documented code
Every public function has JSDoc. Every decision has a rationale. The codebase explains itself — so the next developer doesn't have to guess.
The result: products built for quality, fully documented, and ready to evolve.
Let's work together
Backend architecture, AI integration, full-stack development.
