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.
I developed a social media automation dashboard enabling users to authenticate via Facebook Login, schedule posts, and track engagement analytics in real time. Integrated the Facebook Graph API for user authentication, post publishing, and insights retrieval, while managing webhook updates for page activity.
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.
- Facebook Graph API–powered automation app that enables users to log in, schedule posts, and track real-time engagement analytics using React, Node.js, and Supabase.
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.

I’ve built and deployed multiple backend systems using Node.js, TypeScript, Express.js, and MySQL/PostgreSQL, and I’m eager to contribute my experience while continuing to grow under your mentorship.
Some of my recent work includes:
- FlexCoop – multi-tenant cooperative SaaS built with Node.js, Sequelize, MySQL, and Paystack API for payments.
- nCoder AI – backend microservices with a GraphQL gateway for Salesforce metadata retrieval.
- Fivage – cloud storage SaaS using Node.js, Prisma, and billing/webhook integrations.
- SwapperPlus – Express.js + MongoDB marketplace app with Socket.IO for chat and API integrations.
- SocialBoost – Facebook API Integration Dashboard
I developed a marketing automation dashboard that connects Facebook Pages through secure OAuth2 login, enabling users to schedule posts, publish media, and track engagement metrics in real time. Integrated the Facebook Graph API for content publishing, analytics, and webhook-based updates — reducing manual posting time by 90%. Delivered responsive UI with React and Tailwind, optimized backend performance with Node.js and Supabase, and enhanced campaign visibility for multiple clients.
I’m comfortable collaborating with teams using Git, Supabase/Firebase, and RESTful APIs, and I’m passionate about frontend and backend performance and clean architecture. I’m applying for this junior role because I’m eager to immerse myself in a structured, innovative environment like Avoca AI.
