John Avecilla

• Designed and implemented scalable services using FastAPI and Flask integrating ORM and GraphQL with Python. • Developed and maintained RESTful and GraphQL APIs, ensuring data consistency and type safety across services. • Collaborated closely with frontend teams with React.js applications, implementing form management, state synchronization, and backend integrations. • Automated deployments and CI/CD pipelines using Docker, GitHub and Jenkins, improving release reliability and speed. • Contributed to architectural decisions balancing technical constraints and product timelines, ensuring maintainability and scalability. • Migrated monolithic systems to microservices-based architectures using Golang, Nodejs with AWS improving system scalability and fault tolerance. • Collaborated with UX teams to integrate React frontends with backend services using secure, optimized API endpoints. • Conducted code reviews and implemented best practices for testing, code quality, and documentation.

• Spearheaded the architecture and development of W-Cloud, an enterprise-grade PaaS solution, designed to deliver scalable, fault-tolerant, and high-availability applications for diverse client environments. • Partnered with cross-functional teams (Product, Architecture, DevOps, and QA) to define technical roadmaps and implement mission-critical features including resource orchestration, multi-tenant authentication, observability, and real-time performance monitoring, using Next.js and Tailwind CSS for a seamless user experience. • Architected and optimized API ecosystems to ensure low-latency third-party integrations, enabling secure, scalable data exchange and driving system interoperability across distributed services. • Engineered high-performance services by leveraging Node.js built-in modules combined with advanced caching strategies (Redis, in-memory stores), delivering measurable improvements such as 20–30% faster response times under heavy load. • Built custom Python adapters for Cassandra, enabling seamless integration with the platform’s microservices and achieving c
