I build commerce engines and community platforms.
Software Engineer
Building complete solutions, not just features.
I'm a product-focused engineer who bridges the gap between complex backends and buttery-smooth UIs.
I don't just write code—I ship complete products. From architecting databases to polishing animations, I handle the full stack to deliver systems that scale and interfaces that feel effortless.
Whether it's building a CRM for 10k+ leads, a real-time rider platform, or an AI-powered mobile app, I focus on solving real problems with production-grade solutions.

The tools that matter
Core technologies I use to ship production-grade applications.
Primary Stack
Frameworks & Libraries
Infrastructure & Data
Stability by default
Type-safe systems where the frontend never has to guess.
Architecture First.
I build systems where stability is the default. From strict Zod validation to fully typed API responses, I ensure the frontend never has to guess what the backend is sending.
End-to-end type safety
Zod schemas shared between client and server eliminate runtime surprises.
Validated at the edge
Invalid data never reaches your database. Catch errors early, fix them once.
Self-documenting code
TypeScript + Zod = API contracts that developers trust.
import { z } from 'zod';
// Strict validation schema
export const UserSchema = z.object({
id: z.string().uuid(),
email: z.string().email(),
role: z.enum(['admin', 'user']),
createdAt: z.coerce.date(),
});
// Type-safe API response
export type User = z.infer<typeof UserSchema>;
// Custom hook with full type safety
export function useUser(id: string) {
return UserSchema.parse(data);
}
