Yoandro G.

With 20+ years in software development and technical leadership, I work with startups, agencies, and established companies that need more than basic coding help. I bring senior-level experience across AI development and integration, full-stack development, cloud infrastructure, software architecture, payment systems, performance optimization, and technical team leadership. I have worked with clients and organizations including McDonald’s, Walmart, U.S. Government agencies, Lyft, Hyundai Motors, and large real estate companies. My core strengths include: - Full-stack development with Node.js, PHP, C#, C++, JavaScript, Vue.js, React, Laravel, Symfony, Express, HTML5, CSS, and modern web technologies - AI Systems and sytem integration - SaaS, CRM, dashboard, API, e-commerce, and business application development - AWS, Azure, DigitalOcean, Linode, Linux/Unix server setup, deployment, security, and infrastructure maintenance - Database design, optimization, administration, and performance tuning - Payment processor integrations and PCI-aware architecture - Startup consulting, workflow organization, technical planning, and development team management - Application audits, code reviews, scalability planning, and performance improvements Why clients hire me: I am not just a developer who waits for instructions. I can look at your product, understand your business goals, identify risks, recommend better solutions, and execute. Clients usually come to me when they need someone who can: - Build a product from idea to launch - Fix or modernize an existing application - Improve slow or unstable software - Design scalable backend architecture - Manage or support a development team - Integrate payments, APIs, CRMs, dashboards, or third-party systems - Set up secure cloud infrastructure - Act as a fractional CTO or senior technical advisor I focus on practical, business-driven software. Clean architecture, reliable infrastructure, security, scalability, and maintainability matter — but so do speed, budget, and getting the right version of the product launched. Whether you need hands-on development, technical leadership, or a trusted consultant to review your current system, I can help you move faster with fewer mistakes. Send me a message and tell me what you are building, fixing, or trying to scale. I’ll help you figure out the best technical path forward.
