Cursor

Async/Await Promise Chain Broken
After Cursor refactored your async/await code, promises are no longer resolving correctly. Operations that should happen sequentially are executing out of order, causing data inconsistencies.
Async/await syntax or promise handling was likely changed incorrectly.
Error Messages You Might See
Cannot read property of undefined
Promise rejection: undefined
Data not loaded
Operation executed out of order
Common Causes
- Missing await on async function call, continuing before completion
- Promise.all used with dependent operations (order matters)
- Try/catch removed, unhandled promise rejections
- Async function syntax broken (async not declared)
- Return statement missing in async function
How to Fix It
Always await async calls: const data = await fetchData(). Use Promise.all for parallel: Promise.all([fetch1, fetch2]). Use .then() chain for sequential. Wrap in try/catch: try { ... } catch(e) { ... }. Verify async function returns Promise.

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’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

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.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
When should I use Promise.all?
For parallel independent operations. Promise.all(promises) waits for all. Fails if any rejects.
How do I handle async errors?
try/catch with await. Or .catch() on promise. Don't ignore errors - they'll cause bugs.
