As a seasoned engineer with over five years in complex software systems across multiple industries (such as Logistics systems, HealthTech, EdTech, among others), I bridge the gap between complex technical challenges and accessible solutions. My expertise in cloud-based applications isn't just about writing code, it's about making technology work for people. Whether you're struggling with debugging code, designing efficient algorithms, or navigating complex system architectures, I've been in your shoes. I've developed enterprise applications from the ground up and guided hundreds of learners through challenges ranging from basic syntax errors to advanced architectural decisions. **What sets me apart? I don't just solve problems, I help you understand them. My approach combines hands-on engineering experience with a talent for explaining complex concepts in straightforward terms. From untangling complex code issues to optimizing system performance, I translate technical challenges into clear, actionable steps**. My greatest achievement isn't the systems I've built, it's watching my mentees transform from curious beginners to confident professionals. This journey has sharpened my ability to meet you exactly where you are—whether you need an expert to help resolve a persistent bug or a patient guide through new programming paradigms. **Let me help you turn technical obstacles into opportunities for growth.**

My experience has ranged from an individual software contributor, through as technical team lead. Cumulatively, I have about 7 years post qualification experience as a software engineer. I have worked with multiple technologies on projects where my role includes building software features, scaling existing legacy applications mentoring junior developers and ensuring product success. As a software engineer I think first in algorithms, data structure, design, analysis and architectural patterns when solving problems. I tend to think in a non language agnostic manner, however I favour some technological stack over others as defined: I have experience in Javascript, Python, Rust, Kotlin and C++. I have an excellent understanding of these language features and I have built solutions with regards. I also have decent skills in user interface development. And building backend services and RESTFUL Apis. I am currently running MSC in computer science with Georgia Tech.

Is your AI-powered MVP built on a fragile 'vibe-coded' foundation? Are you struggling to scale a prototype that was built with lightning speed but is now plagued by bugs, security holes, and technical debt? I transform brittle AI prototypes into robust, **production-ready applications**. As a senior AI engineer specializing in the **Node.js** and **React** ecosystem, I bridge the gap between rapid, AI-assisted development and the disciplined engineering required for scalable, secure software. But robust software is only half the battle. The other half is making it *work for your business*. I design and implement **intelligent automation workflows** that connect your apps, eliminate manual tasks, and free up your team to focus on high-impact work. Whether you need to rescue a failing project, automate a core business process, or build a scalable MVP from the ground up, I provide the expert oversight to ensure your AI initiatives deliver real, measurable value. **My Core Services:** * **🤖 AI Code Rescue & Remediation:** I conduct deep **AI code audits** to debug, refactor, and secure fragile codebases (especially those built with LangChain.js). I turn unmaintainable prototypes into stable, scalable assets ready for real users. * **⚙️ Intelligent Workflow Automation & Integration:** I design and build digital assembly lines for your business. I offer a full spectrum of automation solutions: * **Rapid Integration:** Using **Zapier, Make.com & n8n** to connect your existing tools and solve immediate process bottlenecks. * **Custom API Development:** Building custom **Node.js** APIs and webhooks to connect proprietary systems or handle complex logic that no-code tools can't. * **AI-Powered Decisions:** Infusing your workflows with intelligence using the **OpenAI API** to triage support tickets, qualify sales leads, or generate content automatically. * **🚀 Custom AI Solution Development:** I architect and build bespoke AI solutions from scratch, from **Custom GPTs** and intelligent **AI Agents** to complex RAG (Retrieval-Augmented Generation) pipelines that leverage your private data. * **👨‍🏫 AI Engineer & Career Mentorship:** I provide 1-on-1 coaching to help developers navigate the AI landscape, master tools like LangChain.js, and build a successful career in AI engineering and automation. **My Tech Stack:** * **Languages:** Node.js, TypeScript, JavaScript * **Frameworks:** React, Next.js, Express.js, NestJS * **AI / LLM:** LangChain.js, OpenAI API, LlamaIndex, Vector Databases (Pinecone, Qdrant) * **Automation Platforms:** Zapier, Make.com, n8n Ready to move past the prototype phase and build a real business? **Send me a message with your project details or book a session to get started.** --- ### Service Packages * **Package 1: AI Code Audit & Production-Ready Roadmap** * **Description:** Have an AI-generated MVP that feels unstable? I'll perform a comprehensive review of your codebase. You'll receive a detailed report identifying security vulnerabilities, performance bottlenecks, and a concrete, actionable roadmap to make your application **production-ready**. This is the perfect first step to de-risk your project. * **Package 2: Intelligent Automation Workflow** * **Description:** Let's put a core business process on autopilot. We'll map out a high-impact workflow and I'll build a robust automation to solve it. Ideal for **automating lead qualification**, **triaging customer support tickets**, or **streamlining content pipelines** using the best tool for the job—Zapier, Make, or custom Node.js scripts. * **Package 3: Scalable AI MVP Development** * **Description:** Need to build an MVP the *right* way? I'll architect and develop a **scalable MVP** from day one, using professional, spec-driven development practices. We'll build a strong foundation with clean, documented code and a modern stack (Node.js, React) to avoid the technical debt that plagues "vibe-coded" projects.
