Job Success
Dhaka, Bangladesh - 10:34 pm local time
Most businesses don't need another generic website. They need a high-performance, AI-search optimized web application that actually scales.
For 12 years I ran a digital agency, training and managing 30+ developers. I understand complex deployments, clean code, and clear communication — not just the technical execution. Today I work directly as a senior hands-on engineer for digital agencies, e-commerce founders, and tech startups.
→ My Core Technical Stack:
- Modern JavaScript: React, Next.js, Node.js, Tailwind CSS
- Advanced CMS & E-Commerce: Headless WordPress (Gutenberg/ACF), Shopify, WooCommerce
- Backend & Architecture: Laravel, PHP, RESTful API Integration
- Growth & Optimization: Technical SEO, Speed Optimization, Core Web Vitals
→ How I work:
I don't take orders and disappear. I act as your technical partner — whether that's migrating WordPress to Headless Next.js, integrating complex APIs (recent work includes Thareja.AI), or fixing a broken WooCommerce checkout under live traffic. Project management tools like Asana, Slack, and Jira are part of my daily workflow.
If you're tired of developers who go silent or need constant hand-holding — send me a message. Let's map out your next build.
