Chard Gonzales
@chardgonzales
Senior software engineer specializing in Ruby on Rails, secure API integrations, and scalable AWS/Heroku systems.
What I'm looking for
I’m a Senior Software Engineer with nearly 20 years of experience designing, building, and maintaining production web and mobile applications. I bring deep expertise in Ruby on Rails, PostgreSQL, and complex third-party API integrations, delivering end-to-end solutions from product discovery to long-term architectural stability on Heroku and AWS. I’m especially strong in turning business requirements into reliable systems—through disciplined development, testing, and deployment.
In my recent work, I’ve integrated Stripe and GoCardless payment gateways and built bidirectional Salesforce↔PostgreSQL synchronization using Heroku Connect to keep business-critical data consistent. I also optimize performance by tuning PostgreSQL queries and scaling background processing with Sidekiq and Redis, and I lead meaningful modernization efforts (including upgrading legacy Rails applications from 6.x through 8.1). I enjoy technical leadership—leading distributed engineering teams and mentoring developers across regions—to raise quality and deliver outcomes confidently.
