Hi, my name is

Nahid Hossain

Engineering Reliability into AI Automation & Scalable Systems

Senior Software Engineer | AI Automation Architect | Vibe Coding Specialist

I bridge the gap between AI speed and enterprise reliability. With over 13+ years of engineering experience, I don't just generate code - I architect systems.

I specialize in AI Automation workflows for US-based firms, optimizing legacy monoliths, and building concurrent microservices in Go and Python. I am the "Human-in-the-Loop" who turns AI-generated prototypes ("Vibe Coding") into secure, scalable, production-grade software.

01. About Me

Engineering Logic, Not Just Syntax

Hello! I'm Nahid - a Senior Software Engineer who has spent 13+ years building backend systems in PHP and Python, and in the last few years shifted that experience toward AI automation and agentic workflows.

Today I design Zapier and n8n automations, integrate LLM APIs (OpenAI, Anthropic, Gemini) into business tools, and build AI agents that handle real operational work for US-based companies. I also use AI coding tools like Cursor and GitHub Copilot to rapidly prototype applications - what's now called Vibe Coding - and then I do what most people skip: I refactor and harden that AI-generated code until it's production-grade. I'm the Human-in-the-Loop who makes sure things actually work.

Currently, I work remotely as a Software Engineer in Automation & AI for The VAM Group (USA).

Previously, I built automation workflows for Ignite Chiropractic (USA), architected a scalable SaaS influencer marketing platform at GrowSocial (Malta), and led development teams at Airgigs (USA) and Computer Source (Bangladesh).

02. Skills & Expertise

Technologies I work with

I've worked with a wide range of technologies. Here's an overview of my technical expertise.

AI & Automation

Building intelligent, agentic workflows that connect AI models to real business operations. I integrate LLM APIs (OpenAI, Anthropic Claude, Google Gemini), orchestrate multi-step agents with LangChain, LlamaIndex, and CrewAI, and automate repetitive work with Zapier, n8n, and Make.com.

LLM Integration Prompt Engineering RAG Agentic Workflows CrewAI LangChain LlamaIndex Zapier n8n Make.com

Vibe Coding & AI Development Tools

I use AI coding tools to prototype fast and then clean up the output for production. This means rapid development with Cursor, GitHub Copilot, Windsurf, Google Antigravity, and Claude Code, followed by thorough refactoring, security hardening, and architecture cleanup - the "Human-in-the-Loop" approach.

Data & Search

Designing data layers for speed and scale. Relational databases (MySQL, PostgreSQL, SQL Server, SQLite), Redis for caching, and Elasticsearch for real-time search and analytics across millions of records.

ElasticSearch Redis PostgreSQL MySQL Social Data Mining SQL Server SQLite

Backend & Frameworks

The engineering foundation behind everything else. I build APIs, SaaS platforms, and microservices using PHP (Symfony, Laravel, Yii, CodeIgniter, Zend/Laminas), Python (FastAPI, SQLAlchemy), and Go for high-concurrency services.

Frontend & Mobile

Building responsive interfaces and cross-platform mobile apps. I work with React.js, Vue.js, Alpine.js, Stimulus, jQuery, Tailwind CSS, and Bootstrap on the web, and Flutter/Dart for mobile.

Cloud & DevOps

Architecting cost-effective, resilient infrastructure. I've migrated expensive AWS setups to Hetzner cloud (cutting costs 50%), containerized applications with Docker and Kubernetes, and managed Linux servers with automated CI/CD pipelines.

APIs & Integration

Designing and consuming robust APIs for system integration. REST, GraphQL, SOAP, OAuth, API Keys, and JWT authentication.
