Barranquilla, Colombia (Remote)
LinkedIn: ralvarezcorrea • GitHub: github.com/rialco
SUMMARY
Staff-level backend engineer with experience delivering production systems in
TypeScript/Node.js across consulting/product environments (LI.FI, Globant) and e-commerce
operations (Crescent Garden), plus founder-led ownership building SaaS (Binah). Strong in API
design, integrations, reliability, and automation. Hands-on building AI workflows and
agent-like systems (intent routing + tool use) to reduce manual work, accelerate execution,
and improve consistency.
CORE SKILLS
Backend: TypeScript, Node.js, Fastify/Express, REST APIs, Webhooks, Integrations, Auth
(JWT/SSO patterns), Testing (Jest)
Automation/AI: agent-style workflows (intent routing, tool use), structured outputs
(JSON/schemas), prompt/tool design, workflow automation (n8n-style), reliability guardrails
(validation, fallbacks, logging)
Data: SQL (Postgres/MySQL), data modeling, operational reporting
Infra: Docker, Linux (Debian), Nginx, Cloudflare, CI/CD fundamentals, observability mindset
Domain: E-commerce ops, order lifecycle, support automation, notifications
EXPERIENCE
Binah — Technical Founder / Lead Engineer (SaaS: CRM/ERP-lite for
LATAM e-commerce)
2025 – 2026 | Remote
● Built and owned a SaaS platform end-to-end, turning messy operational workflows
(WhatsApp + spreadsheets + manual ops) into scalable systems.
● Designed backend architecture: data models, APIs, permissions, and integration
patterns for e-commerce-oriented workflows.
● Implemented AI-assisted automation using intent-based routing + tool-driven flows to
handle repetitive tasks consistently (structured outputs, validation, fallbacks).
● Shipped workflow features around contact management, tagging/segmentation,
operational tracking, and automated notifications.
LI.FI — Backend Developer (TypeScript/Node.js)
Jan 2023 – Sep 2024 | Remote
● Delivered backend features and API improvements with emphasis on correctness,
performance, and clean contracts.
● Built production integration patterns (webhooks/third-party APIs) with idempotency,
retries, validation, and robust error handling.
● Improved reliability through stronger automated tests (Jest), better edge-case handling,
and production debugging with root-cause fixes.
● Collaborated across teams via code reviews, estimation, and delivery ownership to
ship predictable releases.
Tech: TypeScript, Node.js, REST, integrations, Jest
Globant — Full-Stack Developer / Consultant
Feb 2022 – Jan 2023
● Shipped features across backend and frontend in client environments, adapting quickly
to new codebases and delivery processes.
● Supported modernization initiatives: improved maintainability, service-oriented patterns,
and standardized auth/testing practices.
● Implemented JWT-based auth flows and expanded test coverage to reduce regressions
and improve release confidence.
Tech: Node.js/TypeScript, JWT, Jest, modern web stacks
Crescent Garden — Lead Engineer (E-commerce Platform)
Sep 2024 – Present
● Technical owner of a production WooCommerce ecosystem; led improvements across
performance, stability, SEO hygiene, and operational tooling.
● Built and maintained WooCommerce customizations (templates, attributes, analytics
hooks), reducing operational friction and improving reliability.
● Diagnosed plugin conflicts and production issues; improved uptime and reduced
regressions through safer change practices.
● Added automation to streamline repetitive operational tasks and content workflows,
improving team speed and consistency.
Tech: WordPress, WooCommerce, PHP, GTM/analytics, Cloudflare
AI WORKFLOWS & AUTOMATION
● Agent-style productivity workflows: built intent-based systems that route tasks to
specialized “sub-agents” and tools, returning structured outputs (JSON) with validation +
fallbacks.
● AI-assisted development (“vibe coding”): rapidly built an expense tracker app using
AI-driven iteration to prototype, refine UX, and ship working features faster (tight
feedback loops + code generation + refactors).
● Applied reliability patterns: schema-driven outputs, deterministic formatting, defensive
parsing, and logging for debugging and iteration.
PROJECTS
● Expense Tracker App (AI-assisted build): rapid end-to-end build using AI-driven
iteration (“vibe coding”) to accelerate development and ship a functional app quickly.
● Shopify Orders Sync Service: pulls store orders via API into a database with
pagination/backfills; focuses on consistency, idempotency, and operational monitoring.
● Production-like Infrastructure Lab: Proxmox + VLAN segmentation (OPNsense),
Docker/Portainer services, Cloudflare edge + Nginx routing for realistic
deployment/reliability validation.
