Ifeanyi Elvis Okeke
›Data Engineer & Software Engineer — Python, PySpark & AI
I build data pipelines, production-focused web applications, APIs, and AI-powered backend systems.
Featured work
Real, working systems, not tutorials. Each one is live on GitHub.
Claims Pipeline
An end-to-end insurance claims data pipeline built to mirror how a real data engineering team would structure the work: synthetic data generation, PySpark bronze/silver/gold layers with data quality checks, a fraud-risk model tracked in MLflow, LLM-based extraction from unstructured claim text, and a FastAPI scoring service running in Docker with CI/CD.
OpsPilot
An AI-powered monitoring dashboard that watches services in real time, detects incidents automatically, and uses AI to explain what broke in plain language, in the user's preferred language.
AI Document Intelligence API
A RAG platform that ingests PDF and DOCX documents, generates semantic embeddings, stores them in PostgreSQL with pgvector, and answers questions using retrieved, source-aware context.
FastAPI User CRUD
A clean REST API for managing users, supporting full CRUD and search, built to demonstrate solid API design fundamentals.
What I can build for you
From a single feature to a full system, backend, frontend, and the infrastructure in between.
Data Pipelines
End-to-end data pipelines with layered (bronze/silver/gold) architecture, data quality checks, and PySpark processing.
Web Applications
Full-stack web apps built with modern frameworks, from a first prototype to something production-ready.
Websites
Fast, clean marketing and portfolio sites that load quickly and represent a brand properly.
Mobile Apps
Cross-platform mobile apps connected to real backends and APIs, not just static screens.
RAG Systems
Retrieval-augmented generation pipelines: document ingestion, embeddings, vector search, and grounded LLM answers.
Microservices
Backend systems split into focused, independently deployable services with clear API boundaries.
Cloud & DevOps
Deployment pipelines, containerization, and cloud infrastructure so your app actually stays online.
Technical Communication
Technical English communication, IT documentation, and knowledge transfer across software, systems, and engineering teams.
Experience
Data & Software Engineer
Freelance / Self-Directed Projects
- Built an end-to-end insurance claims data pipeline with PySpark bronze/silver/gold layers, data quality checks, an MLflow-tracked fraud-risk model, and a FastAPI scoring service, with CI/CD via GitHub Actions.
- Automated AWS resource reporting across S3 and EC2 using Boto3, with an introduction to infrastructure-as-code using AWS CDK.
- Built web and mobile applications for business clients using modern frontend and backend technologies.
- Designed and integrated REST APIs and PostgreSQL-backed application services.
- Developed a React Native mobile application for a business client from initial UI iterations through functional delivery.
- Built Python automation and backend projects using FastAPI, PostgreSQL and Docker.
- Integrated third-party APIs and worked across application debugging, deployment and maintenance.
- Applied Git-based development workflows and automated testing to backend projects.
Application Engineer / UI Developer
ProvidusBank
- Built and maintained financial technology applications and payment platforms
- Handled REST API integrations across web and mobile products
- Served as a first point of contact for live production incidents, diagnosing issues, guiding stakeholders through resolution steps, and escalating to the right team under time pressure
