Services

How we can work together.

Whether you are hiring an engineer, launching a store, or need an existing codebase to behave — the work below is what I do most.

  • Joining a startup

    Full-stack or founding engineer, full-time.

    Turning a product vision into something in front of users. I take ownership across the stack and ship the first version, then the version that scales.

    • Founding and full-time engineering roles
    • Rapid MVP development
    • Scalable backend and cloud infrastructure

  • Jewelry & luxury retail

    Storefronts built for high-consideration purchases.

    Online stores for jewelers and premium retailers, with 3D product preview, gemstone configurators and checkout that holds up at high order values.

    • Interactive 3D product viewers
    • Stripe and Shopify integration
    • Multi-currency checkout

  • Freelance & contract

    Scoped projects, audits and rescue work.

    Working directly with founders and agencies to build applications, refactor codebases that have outgrown themselves, and fix what is slow.

    • End-to-end web applications
    • Performance and SEO audits
    • Custom API and database work

  • AI & automation

    LLM features and pipelines that remove manual work.

    Integrating language models into real products, automating data collection, and building the backend services that keep them fed.

    • LLM and AI agent integration
    • Automated data pipelines
    • REST and GraphQL APIs

About

Who you would be working with.

I am a full-stack engineer based in Visakhapatnam. Most of my work is early: joining a small team as a core engineer and building the 0-to-1 web application, or building a jewelry storefront from the product photography up. I like the part of the job where the product does not exist yet.

Code

How the work reads up close.

Three pieces pulled from the projects above.

The hook behind the review tool: one call site, loading state that cannot get stuck.

TypeScript
import { useState, useCallback } from "react"; export interface SentimentResult {  score: number; // -1.0 to 1.0  label: "POSITIVE" | "NEUTRAL" | "NEGATIVE";  keywords: string[];} export function useSentimentScanner() {  const [isScanning, setIsScanning] = useState(false);   const scanText = useCallback(async (text: string): Promise<SentimentResult> => {    setIsScanning(true);    try {      const response = await fetch("/api/ai/sentiment", {        method: "POST",        headers: { "Content-Type": "application/json" },        body: JSON.stringify({ text }),      });      const data = await response.json();      return data.result;    } finally {      setIsScanning(false);    }  }, []);   return { scanText, isScanning };}
