I architect software systems end-to-end: from service boundaries, APIs, and data flows to cloud infrastructure, delivery pipelines, and day‑2 operations. AWS is the platform I use most, but my core value is software architecture under real constraints: reliability, cost, security, latency, maintainability, and teams that need to ship. Lately that is mostly applied to Generative AI applications.

I’m a Sr Innovation Architect (Office of the CTO) at Caylent. I also write Simple AWS, a weekly newsletter read by 45k+ engineers, architects and team leads who want clear explanations and practical patterns, not copy‑pasted architectures.

Advisory & consulting (where I’m most useful)
- Architecture reviews and “what should we build next?” roadmaps (software + cloud, GenAI)
- High-stakes tradeoffs: build vs buy, serverless vs containers, async vs sync, data modeling and boundaries
- GenAI solution architecture: production patterns, evaluations, model selection, production deployments and best practices, cost/latency tradeoffs, and integration into existing products
- Cloud-native architectures on AWS (serverless, event-driven, containers where it fits, networking and security)
- Delivery practices for code (Python, JavaScript/TypeScript) and Infrastructure as Code (CDK, Terraform, CloudFormation)
- Enablement: workshops, presales support, and technical talks for teams and leadership

Credibility (high level)
- 11+ years building software professionally; 25+ projects across startups, enterprises and SMBs
- AWS Solutions Architect Professional; AWS Community Builder and Builder of the Year award winner; former AWS Authorized Instructor
- International speaker (Argentina, US, Mexico, Colombia, and looking to expand this list)

I’m not actively job-hunting, but I’m open to selective advisory/consulting engagements (reviews, workshops, short-term roadmap work, or fractional architecture and technology support). If you think I can help, DM me.

Guille Ojeda

My journey in the world of technology began with a deep curiosity for how things work and a strong academic foundation that led me to earn a Ph.D., Master's, and Bachelor's degree in Computer Science. This passion for solving complex problems quickly evolved into a career where I’ve spent years designing and implementing enterprise solutions that create real, measurable impact.

Starting as a software developer, I quickly gravitated toward architecture, where I found my strength in seeing the big picture connecting business goals with technical execution. Over time, I transitioned into Solution Architecture, working with large-scale organizations to build robust, scalable, and cloud-native systems. These experiences deepened my expertise in designing software ecosystems that are not only technically sound but strategically aligned.

My professional evolution has been driven by three core pillars: architecture excellence, cloud transformation, and leadership. I’ve had the privilege of leading high-performing development teams, guiding digital modernization initiatives, and helping enterprises adopt Azure and AWS cloud platforms with confidence and clarity.

Key milestones along this journey include:
- Designing resilient, mission-critical architectures in fast-paced, enterprise environments.
- Leading cloud migration and modernization projects with a focus on performance, scalability, and maintainability.
- Earning certifications in Azure, AWS, and Scrum to back my hands-on experience with recognized industry standards.

What sets me apart is my ability to bridge the gap between technical depth and business strategy. My clients and teams value my ability to translate abstract goals into executable, efficient solutions. I lead with a collaborative spirit, bringing both vision and pragmatism to the table.

Today, as a Solution Architect and IT Leader, I continue to tackle new challenges, mentor talented professionals, and deliver software solutions that go far beyond code, driving transformation, innovation, and long-term value.
