Hi, I'm CJ.
I'm a Software Engineer
I've spent the last 3 years learning and building software.
About.
Hey! I'm CJ Francisco, if you haven't already gathered that by now. I'm a software engineer from Rizal, Philippines, who loves solving problems. That passion led me to specialize in backend development, primarily cloud native applications with Node.js and Python. I also enjoy building with whatever tools are right for the job.
Outside of work, I love to travel and play guitar even tho I'm still bad at it : ) and code new projects in my free time.
Use at work
Use for fun
Projects.
Experience.
Developed and maintained scalable AWS-based backend systems, implemented secure authentication and payment features, and contributed to both web and mobile application development.
Focusing on cloud-native applications, I built an internal email management system using AWS SES for validation and spam filtering, with all data stored in S3. Integrated AWS Bedrock into a RAG pipeline to index and summarize emails and documents for clients. Developed secure Python APIs with AWS Cognito authentication, deploying infrastructure via CloudFormation. Created a Lambda@Edge image-resizing service (CloudFront/S3), established CI/CD pipelines with CodeBuild and CodePipeline (GitHub), and automated operations with Bash.
Built and maintained a Flask-based backend featuring booking, e-commerce, offers, notifications, chat support, admin dashboard, member organization, rewards redemption, and KYC-enabled seller onboarding with live chat between buyers and sellers. Integrated RabbitMQ for email offloading and refined a Beautiful Soup scraper for alcohol sites. Deployed to DigitalOcean using systemd services, Nginx, and Cloudflare DNS, managing the network and production environment.
