Dhaka, Bangladesh - 7:53 pm local time
With over 10 years of enterprise-grade software engineering experience and a Top Rated Plus status on Upwork, I don't just write code—I build intelligent, automated systems that scale businesses. My core philosophy is simple: technical excellence is measured solely by client success and flawless execution.

As a full-stack engineer, my unique advantage is bridging the gap between cutting-edge AI and traditional web/mobile architectures. While low-code freelancers struggle with API limitations, custom tokens, or database bottlenecks, I write custom backend code, design scalable architectures, and seamlessly embed AI agents directly into your ecosystem.

🧠 AI ENHANCEMENT & INTELLIGENT WORKFLOWS
I help businesses transition into the AI era by building smart systems that automate manual operations, extract hidden data insights, and lower operational overhead.
* Custom AI Agents: Integrating OpenAI (ChatGPT), Anthropic, and open-source LLMs into web apps, CRMs, and SaaS products.
* Advanced Workflow Automation: Building intricate, self-healing automation pipelines using N8N, handling custom JavaScript nodes, webhooks, and multi-app syncs.
* Intelligent Data Extraction: High-scale data scraping, processing raw inputs, and utilizing AI for automated data enrichment and lead generation.

📱 FULL-STACK WEB & MOBILE ARCHITECTURE
From single-page applications to cross-platform mobile apps, I deliver end-to-end solutions with optimized performance and secure database design.
* Mobile Development: High-performance, pixel-perfect iOS and Android apps engineered with Flutter, including deep API integrations and app store deployment.
* Frontend Ecosystems: Modern user interfaces built with React, Next.js, Vue.js, Angular, and Tailwind CSS.
* Backend & Custom Software: Core PHP, Laravel, CodeIgniter, and Node.js.
* Relational & NoSQL Databases: MySQL, PostgreSQL, MSSQL, and MongoDB.

🔌 PLATFORM CUSTOMIZATION & ENTERPRISE APPLICATIONS
I deeply customize and extend market-leading software to fit your exact business workflows, building bespoke features that don't break during core updates.
* ERP & CRM Systems: End-to-end module development, setup, and structural customization for Perfex CRM and Odoo ERP.
* E-Commerce Scale: Custom theme development, plugin creation, and advanced API syncs for WordPress (WooCommerce), OpenCart, and Shopify.
* Cloud Infrastructure: Deploying and managing applications securely using Amazon Web Services (AWS EC2, S3) and modern server environments.
* Institutional Repository Systems: Advanced installation, migration, and custom UI tailoring for DSpace platforms.

🚀 CONVERSION FUNNELS & MARKETING AUTOMATION (GOHIGHLEVEL & CLICKFUNNELS)
I engineer high-converting marketing architectures that capture leads and turn them into paying customers automatically. I help agencies consolidate their software stacks, lower costs, and eliminate revenue leaks.
* GoHighLevel (GHL) Architecture: Expert configuration of GHL sub-accounts, GHL website design, GHL landing page, GHL sales funnel, complex snapshot deployment, visual pipeline setup, and two-way SMS/Email system integration.
* Advanced GHL Workflows: Building behavioral automation sequences (e.g., missed-call text-back loops, automated review requests, and multi-channel drip campaigns).
* ClickFunnels Mastery: Designing, troubleshooting, and optimizing high-converting sales funnels, order bumps, one-click upsells, and membership portals.
* Frictionless Funnel Migrations: Seamlessly transferring landing pages, contacts, and email assets from ClickFunnels into GoHighLevel without disrupting ongoing campaigns.
* AI-Driven Funnel Operations: Embedding HighLevel's native AI or connecting N8N to automate appointment scheduling, qualify inbound leads, and handle real-time lead responses.
