Architecture + Execution,
From Idea to Production

I work with founders and software teams as a senior technical partner — combining architecture and execution. From product architecture and MVP build to backend systems, DevOps, AI integration and ongoing technical partnership.

01MVP Build

Product Architecture & MVP Build

I help founders design the architecture, build the core product and set up the technical foundation for future scale — fast enough to launch, structured enough to grow.

This is for you if
  • You have a product idea and need a technical partner who can design and build it.
  • You are a startup building your first MVP.
  • You are building an internal platform or tool.
  • You need more than a no-code prototype.
  • You want to avoid rebuilding everything after the MVP.
  • You need architecture, backend and delivery handled by one senior person.
What's included
  • Product and technical discovery
  • MVP scope definition
  • Architecture design
  • Backend development
  • Full-stack implementation when needed
  • Database design
  • Authentication and user flows
  • API design
  • DevOps setup and deployment pipeline
  • Basic monitoring
  • AI-assisted development workflow
  • Technical documentation
02AI-Accelerated

AI-Accelerated Product Engineering

I use AI-assisted engineering workflows to build faster while keeping architecture, code quality and production reliability under control. The goal is not more code — it is a better product, shipped faster.

This is for you if
  • You need to move fast without sacrificing quality.
  • You want to adopt AI-assisted development the right way.
  • You are under time pressure to ship a product.
  • You worry AI-generated code will create technical chaos.
  • You need senior review on AI-assisted output.
  • You want to increase delivery speed without growing the team.
What's included
  • AI-assisted development workflow setup
  • Fast MVP implementation
  • Architecture-first prompting and planning
  • Code generation with senior review
  • Rapid frontend/backend iteration
  • Automated documentation
  • Refactoring support
  • Testing support
  • AI-assisted technical research
  • Production-readiness review
03Backend Architecture

Backend & Microservices Architecture

I design backend systems, service boundaries and APIs for products that need to scale beyond a prototype — modular monolith, microservices or hybrid, chosen to fit the product rather than the trend.

This is for you if
  • Your backend is becoming hard to change.
  • Your product is outgrowing a simple prototype.
  • You are unsure whether to use microservices or a monolith.
  • Your service boundaries or API contracts are unclear.
  • You are hitting scalability or performance limits.
  • You are planning a modular monolith to microservices transition.
What's included
  • Backend architecture design
  • Modular monolith design
  • Microservices boundary design
  • API contracts
  • Database design
  • Service communication patterns
  • Event-driven architecture when needed
  • Authentication and authorization architecture
  • Integration patterns
  • Scalability planning
  • Performance bottleneck analysis
  • Technical documentation
04Architecture Audit

Technical Architecture Audit

A focused technical audit for startups and software teams struggling with slow delivery, risky deployments, legacy code, unstable architecture or unclear technical direction.

This is for you if
  • Your team ships slower than before.
  • Deployments are risky or manual.
  • Nobody fully understands the legacy system.
  • Microservices created more complexity than clarity.
  • Backend performance is becoming unpredictable.
  • An AI prototype works, but production reliability is unclear.
  • The founder or CTO needs an external senior technical opinion.
What's included
  • Architecture risk report
  • Backend architecture review
  • Infrastructure review
  • CI/CD and deployment review
  • Delivery bottleneck map
  • Priority fixes
  • 30/60/90 day technical roadmap
  • Final recommendation call
05AI Production

AI Production Integration

I help software teams integrate AI features into real products with proper backend architecture, fallbacks, monitoring, cost control and deployment strategy.

This is for you if
  • You have an AI prototype but it is not production-ready.
  • AI responses are unstable or hard to monitor.
  • Costs and rate limits are unclear.
  • The product needs RAG, vector search or AI workflow integration.
  • The team needs backend architecture around AI features.
  • The AI feature must be reliable enough for real users.
What's included
  • AI architecture review
  • OpenAI / Claude / AI SDK integration
  • RAG and vector database design
  • Prompt and workflow structure
  • Fallback and retry strategy
  • Cost and rate-limit control
  • Monitoring and logging
  • Production deployment plan
06Fractional CTO

Fractional CTO / Architecture Partner

Senior technical leadership for founders and software teams that need architectural direction, delivery discipline and engineering decision-making without hiring a full-time CTO.

This is for you if
  • The company has developers but lacks senior technical direction.
  • The founder needs help making architecture decisions.
  • Delivery is slow and technical priorities are unclear.
  • The team needs better engineering process and standards.
  • The company needs CTO-level support but not a full-time CTO.
  • The product is growing and technical complexity is increasing.
What's included
  • Architecture reviews
  • Technical roadmap
  • Engineering process improvement
  • Code review standards
  • DevOps and infrastructure guidance
  • Hiring and team structure advice
  • Technical decision support
  • Regular leadership calls
07Rescue Sprint

Technical Rescue Sprint

A focused 1–2 week engagement to stabilize critical backend, infrastructure, deployment or architecture problems.

This is for you if
  • Deployments are risky or frequently fail.
  • Production bugs are blocking delivery.
  • The team is constantly firefighting.
  • Backend or infrastructure problems are slowing down releases.
  • Legacy code is preventing important product changes.
  • A senior technical person is needed to quickly identify and fix the most critical issues.
What's included
  • Initial technical diagnosis
  • Prioritized rescue plan
  • Critical backend / infrastructure fixes
  • Deployment stabilization
  • API and integration cleanup
  • Basic rollback / monitoring improvements
  • Technical handoff documentation

Engagement Models

Architecture Audit

A fixed-scope review of architecture, infrastructure and delivery — ending with a prioritized risk report and a 30/60/90 day roadmap.

Technical Rescue Sprint

A focused 1–2 week engagement to stabilize critical backend, infrastructure, deployment or architecture problems.

Monthly Architecture Retainer

Ongoing fractional CTO and architecture partnership — regular leadership calls, technical direction and delivery discipline.

Project-Based Implementation

Defined deliverables — AI productionization, modernization or platform work — scoped and priced up front.

For very specific advisory work, hourly consulting may be available, but most engagements are fixed-scope or retainer-based.

FAQ

A Fractional CTO provides part-time senior technical leadership to companies that need architectural direction and engineering decision-making but are not ready for a full-time hire. The work covers architecture reviews, technical roadmap, delivery process, code-review standards, DevOps guidance and hiring support.

Most engagements are fixed-scope (architecture audit, rescue sprint, project work) or retainer-based (fractional CTO / monthly architecture partnership). The scope, deliverables and timeline are agreed up front. For very specific advisory work, hourly consulting may be available, but most engagements are fixed-scope or retainer-based.

Slow or risky delivery, unstable architecture, legacy modernization, DevOps and CI/CD hardening, backend performance, and turning AI prototypes into reliable production systems. The common thread is reducing technical risk so teams can ship, maintain and scale.

Node.js, NestJS, React, Next.js, TypeScript, PostgreSQL, MongoDB, Redis, AWS, GCP, Docker, Kubernetes, CI/CD pipelines, and production AI with OpenAI, Claude and the AI SDK (RAG, vector databases, fallbacks and cost control).

I work both remotely and on-site. Based in Barcelona, Spain, I am available globally for remote engagements. On-site Barcelona engagements are available as needed.
