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 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.

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.**
