About Ricardo
Senior Backend Engineer | Go & Python | I ship scalable solutions fast
Jamundi, Colombia - 3:00 am local time
I'm Ricardo, a Senior Software Engineer specializing in Go, Python, and AWS. I've delivered scalable systems for fintech, healthcare, and SaaS companies, handling millions of users, reducing costs, and shipping on time.
Whether you need an MVP built from scratch, a legacy system migrated to the cloud, or complex API integrations, I bring both technical expertise and business understanding to every project.
What I've Built (and the Results)
Fintech (LATAM's fastest-growing credit card company):
- Built CRM unification, ticketing platforms, rewards engines, and chargeback automation
- Reduced error rates from 21.7% to under 5% through system redesign
- Migrated 14M+ customer records with zero downtime
- Shipped complex features in weeks using agile methodologies and CI/CD pipelines
Education & Healthcare:
- National e-learning platform: courses, assessments, digital certifications for thousands of users
- Event registration with QR emails, validation systems, and credential printing
Health & Wellness:
- Nutrition tracking app with restaurant data integration and personalized goals
- Mobile wellness app with content delivery and push notification systems
Startups & MVPs:
- Built production-ready MVPs from concept to launch in 4-6 weeks
- API integrations with Stripe, Twilio, SendGrid, and custom third-party services
- Database optimization reducing query times by 70%+
My Stack & Expertise
- Backend Development: Go, Python, FastAPI, Node.js
- Cloud & DevOps: AWS (ECS, Lambda, S3, API Gateway, SQS, CDK), Docker, CI/CD
- Databases: PostgreSQL, MySQL, Redis, database optimization & migration
- APIs: REST, GraphQL, webhooks, third-party integrations
- Frontend (when needed): TypeScript, React, Next.js
- Tools: GitHub, Jira, Jenkins, Agile/Scrum workflows
- AI-Assisted Development: Claude Code, Cursor, ChatGPT. Shipping 10x faster without sacrificing quality
I choose the right tool for your specific problem: serverless for cost efficiency, containerized services for complex workflows, managed databases when time matters more than customization.
How I Work With Clients
- Fast response times. I'm in Colombia (EST-friendly timezone) and typically respond within hours, not days. Your project moves forward continuously.
- Clear communication. Regular updates, honest timelines, and transparent progress. You'll always know where things stand.
- Business-first approach. I start by understanding your goal, your users, and what success looks like not just the technical spec. This prevents costly rework.
- Production-ready from day one. Clean code, proper error handling, logging, monitoring, and documentation. Systems you can actually maintain and scale.
- Cost-conscious architecture. I work across AWS, Vercel, Netlify, DigitalOcean, and custom VPS setups, choosing the platform that fits your budget and use case. You get systems that scale without burning money on over-provisioned infrastructure.
Why Clients Hire Me
I've built complete systems in weeks that other developers estimated in months. I translate business requirements into scalable solutions, thinking about user experience, operational costs, and long-term maintainability.
I've worked across fintech, healthcare, education, and startups. I know what works, what breaks, and how to avoid expensive mistakes.
When others say "it can't be done on time or budget," I find a way.
