I’m Kevin Coto, a full stack solutions architect based in Dubai. I build cloud native systems for restaurants, fitness, finance, and media. I write about architecture decisions from real production systems.

My work spans two ends of the spectrum. On one side, enterprise platforms for coastal restoration, digital harm reporting, and real time sports scoring built with SST, DynamoDB, and WebSockets. On the other side, AI-powered hospitality tools including a voice receptionist that answers restaurant calls 24/7 and a private feedback platform that helps restaurants improve without public reviews.

I hold the AWS Solutions Architect certification and work across the full stack: Python (FastAPI, Django), TypeScript (SvelteKit, Next.js), and Elixir (Phoenix, Oban). I have written 16 architecture articles covering what I have built and what I have learned from the process.

[ How I work ]

I build systems that last. Then I write about how they work.

• Serverless architecture with SST, DynamoDB Streams, and event driven design
• Polyglot when it helps: Python for APIs, TypeScript for frontends, Elixir for job orchestration
• Document everything. Write about every architecture decision, good or bad.

[ What I have built ]

Real products, real impact.

• Exonic, freelance consulting across South Africa, Europe, and Asia
• Prosperia, AI-driven healthcare solutions for Mexico and the Americas
• Enerex, frontend engineering for energy tech across the USA
• Careem, payment system optimization serving millions in the Middle East
