About

What I do

I am MERN-focused developer building production systems with clean schemas and predictable backend behavior. Designs APIs and data flows that handle real-world complexity, integrations, and messy inputs.

Builds config-driven and event-based systems using tools like RabbitMQ, AWS Lambda, and OpenSearch.

Develops dashboards, no-code tools, and data-heavy applications including stock market platforms and logisctics software. Works across the stack to ship features, debug edge cases, and keep systems stable under load. Prioritize architectures that stay flexible as requirements evolve.

Snippets & Utilities

Small, reusable pieces of code and UI experiments that I find myself using constantly.

useDebounce Hook

A fast, strict debounce hook for React.

export function useDebounce<T>(value: T, delay: number): T {
  const [debouncedValue, setDebouncedValue] = useState<T>(value);
  useEffect(() => {
    const timer = setTimeout(() => setDebouncedValue(value), delay);
    return () => clearTimeout(timer);
  }, [value, delay]);
  return debouncedValue;
}

Tailwind CN wrapper

Merge tailwind classes conditionally without conflicts.

import { clsx, type ClassValue } from "clsx"
import { twMerge } from "tailwind-merge"

export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs))
}

“Reading the cosmos...”

Away from the keyboard I also spend time with astrology. I’m honest about being a learner, there’s always more to study, but I’ve put in enough hours to read charts with confidence: natal work, timing, nakshatras, the usual toolkit.

Sometimes friends ask for a reading over coffee or a call; it stays informal and friendly, not a paid service or a brand. If that’s not your thing, no problem: the rest of this site is about engineering.
