Cesar Canales
Senior Full Stack Software Engineer
8+ years building high-traffic platforms for IBM, 3Pillar Global & Softtek. From migrating 30+ legacy components to optimizing systems serving 1M+ users — I turn complexity into clean, scalable solutions.
About Me
I'm a software engineer passionate about building products that make a real difference. Based in Hidalgo, Mexico, I've spent 8+ years working remotely with international teams, shipping code that serves millions.
At IBM, I modernized the Home Depot platform used by over a million users. At 3Pillar Global, I'm building infrastructure that 1,000+ enterprise clients depend on daily. I bring the same intensity to every project — clean architecture, tested code, and systems that scale.
I believe in TDD, code reviews, and shipping often. I'm comfortable leading migrations, designing APIs, or jumping into a React codebase. What matters to me is building things that work — reliably and at scale.
Why Teams Hire Me Back
High-Impact Delivery
I've built systems serving 1M+ users and managed platforms for 1,000+ enterprise clients. I ship features that move business metrics.
True Full Stack
From React + TypeScript frontends to Java Spring Boot microservices, databases, and CI/CD — I own the entire stack with confidence.
Team Multiplier
I introduce best practices — TDD, GitHub Flow, code reviews, Conventional Commits — that elevate the entire team's velocity.
Legacy Modernization
Migrated 30+ AngularJS components to React at IBM. I know how to modernize codebases without breaking production.
Quality-First Mindset
TDD with Jest, integration testing, high coverage — I write code that doesn't break at 3am. Reliability is non-negotiable.
Remote-Ready
8+ years working with distributed teams across time zones. Async communication, documentation, and self-management are second nature.
