ABUJA, NIGERIA / ENGINEERING PORTFOLIO
Cloud & DevOps Engineer | Full-Stack Developer | AI Engineering
I build cloud infrastructure, automate software delivery, and develop intelligent applications using AWS, Python, React, Docker and modern DevOps technologies.
01 / SELECTED WORK
Inspect the code, understand the decisions, and see where each project stands.
A public portfolio with private-origin delivery and an AWS contact integration.
The problem A static website needs HTTPS delivery, controlled origin access and a contact channel without a dedicated application server.
Project work Built the static application and contact integration; documented private S3/CloudFront hosting and the Lambda/SES backend during Cloud and DevOps practical work.
A traceable path from a Git commit to a container registry.
The problem A containerized web application needs a repeatable image build and a traceable release artifact.
Project work Repository work includes a non-root Nginx Dockerfile and GitHub Actions build, scan and ECR publication workflow.
Declarative replicas, resource budgets and service discovery for a containerized web workload.
The problem A single manually started container has no declarative replica count or stable service abstraction.
Project work Authored Kubernetes manifests for an Nginx deployment with three replicas, resource requests/limits and a NodePort service.
AWS agent orchestration connecting policy retrieval with business-workflow tools.
The problem A support workflow needs to combine policy knowledge with order/inventory actions while tracking the request across tools.
Project work Developed Python multi-agent orchestration with Bedrock/Strands integrations, Knowledge Base retrieval helpers and DynamoDB/Lambda workflow tools.
From word embeddings to retrieval-grounded PDF conversations.
The problem Finding useful information in text and PDFs requires retrieval of relevant context and a clear response when evidence is missing.
Project work Implemented custom GloVe/search components, a retrieval pipeline with abstention behavior and Gemini-powered PDF chat with conversation context and source references.
A conversational assistant with streaming responses and organized chat history.
The problem A useful chat interface needs more than a model call: conversation management, response controls and understandable storage boundaries matter.
Project work Built the Streamlit chat interface, Gemini streaming integration, response-style/temperature controls and conversation create/search/rename/delete flows.

I’m Kefas, a Computer Science undergraduate at Miva Open University, based in Abuja.
I’m interested in the connections between applications, infrastructure and intelligent systems. My projects give me a place to turn theory into working code, investigate failures, and document what I learn.
My next step is an internship or junior role where I can contribute to a team and keep developing my engineering judgment.
