Backend Engineer • Cloud • DevOps
Hi, I’m Ifeoluwa Okesola
I design and build scalable backend systems, automate workflows, and deploy production-ready infrastructure using NodeJS, NestJS, TypeScript, and AWS.

About Me
Building systems that solve real problems
I am a backend engineer with over 3 years of experience building scalable, secure, and efficient systems. I specialize in designing robust APIs and backend architectures using technologies like NestJS, TypeScript, and Node.js.
In my work, I have engineered systems that automate decision-making processes, reduce manual intervention, and improve operational efficiency. From rule-based driver tracking systems to fintech platforms with secure KYC flows, I focus on building solutions that have measurable impact.
Beyond backend development, I also work with cloud infrastructure and DevOps practices, including containerized deployments, CI/CD pipelines, and AWS services. I enjoy thinking through architecture, performance, maintainability, and long-term scalability.

Selected Work
Projects
Cloud Infrastructure for Retail Microservices
Provisioned AWS infrastructure for a retail application on Amazon EKS using Terraform, including segmented networking, load balancing, IAM/RBAC access control, and CI/CD workflows. Designed for real-world deployment and operational efficiency.
Impact
- Designed reproducible infrastructure using Terraform
- Deployed microservices to EKS with private worker nodes
- Implemented IAM and Kubernetes RBAC for secure access control
- Automated terraform plan/apply workflows using GitHub Actions
- Deprovisioned infrastructure after validation to optimize cloud costs
Infrastructure is currently offline to optimize cloud costs. The repository contains reproducible infrastructure code and setup instructions.
Driver Offense Tracking System
A rule-based backend system that tracks driver violations such as speeding and seatbelt offenses, automatically assigns penalty points, and triggers coaching workflows.
Impact
- Reduced manual HR intervention through automation
- Enabled proactive driver performance monitoring
- Improved safety compliance through behavioral tracking
Codebase is private due to company confidentiality.
Fintech Currency Exchange Platform (FxPal)
A secure backend system for a currency exchange platform with real-time processing and multi-level KYC verification.
Impact
- Implemented BVN and tier-based KYC verification
- Integrated real-time financial services
- Built scalable architecture using gRPC
Codebase is private due to company confidentiality.
QR Code Check-in System
A real-time check-in/out system designed to improve efficiency and security during high-traffic events.
Impact
- Reduced check-in time by over 50%
- Eliminated manual entry errors
- Improved security with trackable access
Codebase is private due to project confidentiality.
Engineering Thinking
How I approach backend systems
I approach backend development by thinking in terms of systems, not just features. My focus is on building architectures that are scalable, maintainable, and resilient under real-world usage.
When designing a system, I prioritize clear data flow, separation of concerns, and extensibility. My aim is to ensure that new features can be added with minimal disruption.
I also pay close attention to automation and operational efficiency, reducing manual intervention through well-designed workflows, background processes, and CI/CD pipelines.
Security and performance are always part of the design from the start, not afterthoughts. From implementing access control to designing efficient database queries, I build systems that are reliable in production environments.
