External API Calls Timing Out on Replit
Your app hangs when calling external APIs. Requests to third-party services timeout without response.
Network latency and Replit's resource constraints cause slow API calls.
Error Messages You Might See
SocketTimeoutException: Read timed out
java.net.ConnectException: Connection refused
Connection timeout after 30000ms
Common Causes
- Default HTTP timeout too short (often 0 = infinite)
- External API very slow or unreachable
- Network/DNS resolution slow from Replit
- API missing required authentication headers
- Rate limiting causing delays
How to Fix It
Set explicit connection and read timeouts (5-10 seconds). Use RestTemplate with HttpClientBuilder or WebClient. Implement circuit breaker pattern with Resilience4j to fail fast. Test API connectivity in Replit shell with curl. Consider caching API responses to reduce calls.

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.
