Emmy-Dee
Backend & Systems Engineer
Hi, I'm Emmanuel Ademola
a Backend & Systems Engineer.|
I'm a backend and systems engineer with 5+ years of experience building fintech services, APIs, AI features, and internal tools. I work mostly with Python, Node.js, databases, queues, and cloud tooling. I care about simple designs, clear contracts, and systems that behave well under real use.
Let's build something great together.
My Resume
About Me
I'm Emmanuel Ademola, a backend and systems engineer focused on financial systems, APIs, and
AI-backed product features. Over the last 5+ years, I've worked on services for fintech, learning, travel,
marketplaces, and operations teams.
Most of my work sits at the backend layer: shaping architecture, integrating providers, writing APIs, moving slow
jobs into queues, and cleaning up systems so teams can keep building on them.
I also teach and mentor, so I pay close attention to clear documentation, readable code, and systems other
engineers can pick up quickly.

Skills
Backend Engineering
I build backend services with Python and Node.js, from API design and data modeling to payments, integrations, queues, and background jobs. I focus on code that is clear, testable, and dependable.
Prompt Engineering
I turn LLMs into useful product features, not just demos. I work on prompts, retrieval, chat and voice flows, and backend integrations that make AI features easier to ship and maintain.
DevOps & Cloud
I set up deployments, CI/CD, containers, NGINX, and cloud services across AWS, Azure, and Render so teams can ship changes with fewer surprises.
System Architecture
I design backend structures for fintech, AI, and service-heavy products, including service boundaries, async processing, data flow, observability, and room for the system to grow.
API Design & Docs
I write API contracts with clear validation, authentication, errors, and examples so frontend teams, mobile teams, and external integrators know exactly how to build against them.
Web Development
I can build product-facing web interfaces when the project needs it, but my main strength is connecting the interface to clean backend behavior and dependable integrations.
IoT Development
I build Arduino-based hardware projects with sensors, automation logic, and cloud connections, especially for learning, security, and smart environment use cases.
Tech Training
I teach backend development, coding, and robotics in workshops and classrooms. I break down hard topics into practical steps and help learners build real things.
Technical Writing
I write API docs, engineering notes, and setup guides that help people understand a system without needing a long handover.
