Hi! I’m Jhon, a backend developer based in Colombia. I build tools that connect business systems and reduce repetitive work. I’m currently taking on small paid projects to expand my freelance portfolio and build long-term working relationships. I can help with: WhatsApp Cloud API and Facebook Messenger bots. Lead capture, routing and handoff to a human team. API integrations, webhooks and workflow automation. Backend APIs and internal business tools. AI-assisted bots using DeepSeek or OpenAI models, selected around your needs and budget. My backend stack includes Rust, Axum, SQLx, PostgreSQL and Redis. I also have experience with Go, Laravel, Docker and React. My projects include academic management systems, QR attendance tracking, role-based permissions, real-time notifications and messaging integrations. My introductory rate is $15 USD/hour. Small fixed-price projects are welcome after we agree on the scope. Hosting and third-party API usage are separate. I’m studying English and currently at B1 level. Written communication is my preferred starting point; for calls, a clear agenda helps me prepare. I’m also open to contributing to larger projects through a small paid milestone first.
