How I Work
Discovery & Strategy
We define the exact business problem, target audience, and technical requirements before writing a single line of code.
Architecture & Prototyping
I design the database schema, select the optimal tech stack, and build high-fidelity wireframes to ensure alignment.
Development & QA
Writing clean, modular, and type-safe code. Rigorous manual and automated testing ensures zero critical bugs in production.
Deployment & Support
Deploying to edge networks with CI/CD pipelines, followed by complete documentation and 30 days of post-launch support.
Selected Works
AI Agent Orchestrator
A centralized platform for managing autonomous agents, built with Next.js and Express. Features real-time state synchronization, inter-agent messaging pipelines, and strict access controls via JWT.
The client needed a scalable way to manage 50+ autonomous AI agents concurrently without severe latency, rate-limiting, or state-sync issues.
I architected a custom Redis-backed synchronization layer and a strict JWT-secured inter-agent messaging pipeline using Next.js and Express.
High-Performance E-Commerce
A sharp, modern e-commerce boilerplate prioritizing speed and accessibility. Architected to achieve 99+ Core Web Vitals using an edge-rendered Next.js storefront.
A local retailer's WordPress site was loading in 8+ seconds, causing a 60% bounce rate on mobile devices.
Rebuilt the entire storefront from scratch using Next.js App Router, edge-caching, and a lightweight Fastify backend connected to PostgreSQL.
