Easy 🙂 **Backstory** I started programming in 2018 after my mentor told me that it really fits the way I think. Before I started I was learning marketing, working in Facebook Ads and Shopify Stores (with Google Analytics, VWO, and other website optimization softwares), I was more interested in automation, and building to do tasks only once. I started at first learning Python for automation (which is still my primary language and what I really enjoy coding in). Eventually, I learned that by itself, Python isn't that sharable if you want other non-coders to use the my apps, so I grew my way into web development, diving deep into Django, HTML & CSS, building multiple sites with only those to get experience, for example: - My website: https://www.zackplauche.com/ - A mini app I built: https://www.dollarperhourcalculator.com And more :) Then eventually learning JavaScript and the Vue.js framework to take my websites, designs, and User Experiences to the next level, building at first simple apps like my DollarPerHour Calculator (https://zackplauche.github.io/DollarPerHourCalculator/), and more advanced ones, like the current one I'm developing (still in progress, but it's the biggest app I've ever build, using both Vue.js and Django). I've been teaching programming since 2019, and my students have loved me. I have students I work with that have been working with me weekly since I first started (more than 5 years now!). They helped me keep both my coding and teaching career sustainable as I was helping them with their issues, training them to be effective developers, starting my own software agency, and building my own apps. I'm extremely grateful to my students and truly care about and do my best to support their success in whatever their endeavors.

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.

Freelance API Developer - Omotayo Iyiola

I am a Software Engineer with over 10 years of experience in full-stack development and technical leadership. I specialize in modern web technologies, including JavaScript, TypeScript, React, Node.js, and AWS. My expertise spans frontend frameworks (React, Next.js, Electron), backend architectures (Node.js, Flask), and databases (MySQL, PostgreSQL, MongoDB). I have led diverse projects, from HRIS systems to eVoting platforms, focusing on scalability, security, and system performance. Recently, I developed an AI-driven response evaluator app, enhancing NLP with the Natural library and refining machine learning models, strengthening my AI and model evaluation skills. With a collaborative leadership style grounded in values of Excellence, Passion, Integrity, and Commitment, I have led initiatives that increased revenue and improved institutional rankings, including overseeing the creation of over 15 educational applications at Yaba College of Technology. Cross-platform offline-first POS built with Electron (macOS/Windows) featuring secure role-based sessions, robust API sync (idempotent/outbox), high-performance UI (workers/virtualized lists), and production packaging (code-signed, auto-updates). Also, actively use Cursor, GitHub Copilot, and ChatGPT in my day‑to‑day work. * Cursor: I lean on repo-wide context to refactor legacy modules, generate test suites, run multi-file code mods, and rapidly scaffold React/Next.js features. I also use its inline “chat-on-selection” to explain unfamiliar code paths and to produce migration scripts (e.g., Prisma/PostgreSQL schema changes). * GitHub Copilot: Great for fast boilerplate (handlers, DTOs, Prisma models), unit tests, and typed hooks in TypeScript-heavy codebases. * ChatGPT: Architecture brainstorming, prompt engineering for LLM features (LangChain), complex regex, and translating requirements into clean DDD/Clean Architecture boundaries. This combo has materially reduced cycle time on projects like IntelliTest (AI-powered CBT) and my LangChain eCommerce chatbot, where I used AI tools to scaffold multi-turn LLM workflows, write evaluation chains, and iteratively harden the codebase. My goal is to leverage my technical and leadership skills to drive innovation and deliver transformative solutions aligned with business objectives.
