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 hands-on experience using Python across AI, backend, and automation projects. One of my major works involved using FastAPI to build a LangChain- and Gemini-powered virtual customer service bot integrated with a MySQL database for an e-commerce platform. This bot handled real-time customer queries, fetched answers contextually, and served as an intelligent interface between users and product data. Additionally, I’ve used Flask to develop an AI voice support system powered by ElevenLabs, integrating Retrieval-Augmented Generation (RAG) for voice-based Q&A experiences.
On the infrastructure side, I’ve worked extensively with AWS to deploy, scale, and manage production environments. I’ve used AWS Amplify for CI/CD automation of frontends, EC2 with NGINX for hosting and load balancing, and RDS (MySQL/Postgres) for secure, scalable database management. I’ve also configured Route 53, CloudFront, and S3 Buckets for content delivery and static hosting, ensuring efficient global performance and high availability across deployments.
Together, these experiences demonstrate my ability to bridge AI-powered Python backends with cloud-native AWS deployments, ensuring reliability, scalability, and seamless user experiences across both web and mobile environments.
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.
