Francisco B.

Fractional CTO & Technical Lead with 10+ years of software engineering experience, combining hands-on engineering with product, architecture, and technical leadership. I help startups and technology companies turn complex ideas, existing codebases, and technical challenges into clear architectures, executable roadmaps, reliable products, and production-ready systems. My background spans the full technical lifecycle: 🧭 CTO & Technical Strategy - technical roadmaps, architecture decisions, technology selection, scope definition, technical due diligence, risk management and product/engineering alignment 🏗️ Software Architecture - backend platforms, distributed systems, APIs, real-time systems, data pipelines, cloud infrastructure and scalable product architecture 👥 Technical Leadership - engineering coordination, milestone planning, code and architecture reviews, delivery management, stakeholder communication and production readiness ⚙️ Hands-on Engineering - TypeScript/Node.js, Python, Java, React/Next.js, PostgreSQL, Redis, Docker, APIs, event-driven systems and full-stack/mobile development 🔗 Blockchain & Web3 - one of my core specializations, including DeFi, smart contracts, cross-chain infrastructure, protocol integrations, wallets and transaction systems 🤖 AI & Data Systems - applied AI, automation, data processing, intelligent agents and AI infrastructure I’ve worked as a Founder, CEO, Project Manager, Technical Lead and hands-on engineer, which means I can operate both at the strategic level and deep inside the implementation when required. I have built and led products from discovery and architecture through implementation, hardening, launch and production operations. My experience includes SaaS platforms, APIs, mobile applications, real-time market-data systems, distributed backends, AI infrastructure and production Web3 products. Some highlights: - 10+ years in software engineering and 8+ years in Blockchain/Web3 - Built and led products from zero to production - Co-led a Web3 studio generating €500k+ revenue in 12 months - Delivered production systems for startups, established companies and international clients - Led engineering across backend, frontend, infrastructure, smart contracts and integrations I’m particularly useful when a company needs someone who can connect business goals with engineering reality — whether that’s defining the architecture, leading the development team, rescuing a problematic project, preparing a product for scale, or taking technical ownership of a new venture. If you need a CTO-level partner who can make the technical decisions and still get hands-on when necessary, let’s talk.
