I'm Alejandro Joel Torres González. 11+ years as a Senior Full-Stack Engineer — Vue 3, Nuxt, Go, Python, AWS. I drive architectural decisions through written technical proposals and turn unreliable services into ones teams can rely on.
Driving architectural change through written technical proposals (ADRs) — covering trade-offs in security, RBAC, SSR vs SPA, and microfrontend orchestration with Single-SPA and Nuxt 3.
Taking ownership of unstable systems and turning them around — Go concurrency debugging (race conditions, mutex), database performance tuning, and production on-call with post-mortems.
Vue 3 / Nuxt 3 on the frontend, Go and Python (FastAPI) on the backend, deployed on AWS and Cloudflare. Production LLM integration (OpenAI, Anthropic) for real product workflows.
Authored two technical proposals that shifted a Fortune 500 healthcare client's team away from a less secure Vue 3 + SystemJS SPA setup toward a Nuxt 3 SSR root-orchestrator pattern with server-side RBAC — preserving compatibility with existing Single-SPA microfrontends by embedding them inside the SSR host.
Stack: Nuxt 3, Vue 3, TypeScript, GraphQL, Single-SPA, AWS Lambda, Netflix Conductor
Took over the Go backend of "Cashbacks" after the original engineer left. Over several months, raised SLO from ~60% to a sustained 95–98% by fixing widespread Go panics caused by race conditions, introducing proper mutex usage, rebuilding error handling on the React frontend, and adding read indexes to multi-million-row tables.
Stack: Go (goroutines, channels, mutex), React, TypeScript, PostgreSQL/MySQL
Sole developer for Boho Food Market and Boho Expo — a multi-vertical gastronomic startup. Built two production e-commerce sites (multi-language, 20k+ SKUs), an internal BI tool, a bidirectional ICG ERP integration, and the entire AWS infrastructure — solo, from day one.
Stack: Magento 2, Vue.js, React, Python (Flask, Pandas), AWS (EC2, S3, CloudFront), ICG ERP
Part of the engineering team behind Tienda Naranja, a direct competitor to Mercado Libre. Sustained zero-incident operation through three consecutive high-traffic events — Hot Sale, Black Friday, and Cyber Monday — during 10x+ traffic spikes. Customized Magento 2 checkout, integrated Algolia search, and shipped Auth0 SSO.
Stack: Magento 2, PHP, Laravel, Auth0, Algolia, AWS, Docker, Kubernetes
A comprehensive stack designed for performance, security, and scalability across the entire development lifecycle.
Lead frontend engineer for multinational clients including 3M Health / Solventum and Doosan. Primary engagement on Solventum's Payment Portal and Customer Onboarding platform, serving existing customers (dental clinics, healthcare providers, distributors) for invoice payments and product ordering. The platform progressively migrates legacy data from IBM DB2 into 3M's VIAX ecosystem through GraphQL and event-driven workflows.
★ Authored the architectural proposals that shifted the team toward a Nuxt 3 SSR root-orchestrator pattern, replacing a less secure SPA setup — moving secrets server-side, enforcing RBAC at route + GraphQL layers, while preserving compatibility with existing Single-SPA microfrontends.
Senior engineer on Mercado Pago's internal applications team — building React + Go tooling used daily by Mercado Libre's operations, support, and finance teams to manage refunds, internal money-movement, and cross-application data lookups.
★ Took over technical leadership of "Cashbacks", a critical refunds platform, after the original Go backend engineer left — and raised SLO from ~60% to a sustained 95–98% by fixing race conditions in concurrent goroutines, rebuilding error handling, and adding read indexes to multi-million-row tables.
Full-stack engineer in a 4–5 person team building and maintaining the Magento 2 e-commerce platform for Tienda Naranja, one of Argentina's largest online marketplaces and a direct competitor to Mercado Libre.
★ Sustained zero-incident operation through three consecutive high-traffic events — Hot Sale, Black Friday, and Cyber Monday — Argentina's most demanding e-commerce traffic peaks of the year, during 10x+ traffic spikes.
Sole developer for the company's full tech operation, building and operating every web product end-to-end across the parent company and its startup venture Boho Food Market — a multi-vertical gastronomic concept combining a fresh-food market (produce, fish, butchery, bakery, wine cellar), restaurants on upper floors, and Boho Expo, a curated marketplace for independent artisans.
★ Single-handedly built and operated the entire tech stack for a multi-brand startup: two production e-commerce sites (multi-language, 20k+ SKUs), a bidirectional ICG ERP integration, an internal BI tool, and the full AWS infrastructure — solo, from day one.
Foundation years building e-commerce platforms and backend systems across Spain and Venezuela.
★ Built a Magento 2 storefront from scratch for a marine hardware company with 257k+ products online, integrated with the Amazon Business API for product information uploads.
