Full Stack Systems Engineer
Hi, I'm Jeferson Corral
Architecting robust, resilient, and cloud-native applications across high-concurrency microservices, fintech transaction engines, and reactive modern frontends.
Full-Stack Engineering Across SaaS, FinTech & Marketplaces
Over the past 8+ years, I have built and maintained production systems across B2B SaaS, fintech, iGaming, booking, e-commerce, and insurance. From Laravel/PHP monoliths and multi-tenant SaaS platforms to Node.js/Fastify APIs paired with Next.js storefronts, I deliver reliable backend architecture and clean, accessible frontends.
My current focus centers on the Laravel/PHP ecosystem, Node.js/Fastify/Next.js e-commerce stacks, and multi-tenant SaaS integrations—recently including WorkflowMax (PHCollab) and the RentSync / RentFaster.ca marketplace. I prioritize system reliability, maintainable architecture, and measurable business outcomes.
High Throughput & APIs
Production RESTful APIs and event-driven queues using Laravel, Fastify, Redis/BullMQ, Stripe, Xero, HubSpot, and third-party social integrations.
Domain-Driven Design
Clean service layers, tenant-scoped policies, form requests, typed DTOs, and testable business logic across lending, membership, and booking domains.
Database Tuning
MySQL and PostgreSQL schema design, indexing, query optimization, and zero-downtime migrations for high-volume transactional workloads.
Cloud & CI/CD
Dockerized deployments on AWS and DigitalOcean, CI/CD pipelines, S3/RDS/Spaces storage, and automated testing with PHPUnit, Dusk, and Jest.
