About Me
Hi! My name is Seyr Lemos and I’m a Senior PHP backend developer for more than 14 years. I came from Brazil and I moved to Canada in 2017 (what are you doing here in this cold place? Hard question!) with my beloved wife and my beautiful daughter.
I’m a passionate person and I love what I do. I really believe that technology can help people to have a more dignified life despite the difficulties we may face in our day-a-day.
I’ve been developing projects over the years in different company’s sizes (Governments, medium/large companies, startups) using different stacks and my skills are more focus on
- PHP (Symfony, Laravel and Codeigniter frameworks)
- MySQL and PostgreSQL databases
- Redis and Memcache cache system
- AWS infrastructure (RDS, EC2, SNS)
- Integrations
- POS systems (Vexilor/NCR/DeliverPlus/Revel/VisionMax)
- Payment processors (Bambora/Moneris/PayPal/Givex)
- Delivery System (DoorDash)
- Campaign system (Sendgrid/Mailchimp)
Projects
Here I push all my personal projects and some code challenges I took over the years.
Some projects are abandoned because I didn’t have time update them or was just something sporadic.
