CLOUD NATIVE DEVELOPER / AWS SERVERLESS ENGINEER

I design and ship event-driven systems on AWS: API Gateway, Lambda, SQS, and DynamoDB, wired to full-stack apps built with Next.js and Node.js. Based in Kumasi, Ghana.

SCROLL — SHEET 01

SHEET 01 / PROFILE

Systems thinking,
grounded in code.

I'm a Cloud Native Developer and Computer Science graduate from KNUST, focused on designing and shipping event-driven, serverless systems on AWS.

My core work right now is SentryNode, a fraud detection engine that reacts to transactions in real time: API Gateway takes the request, SQS holds the load, Lambda evaluates risk, DynamoDB stores state, SNS fires the alert. MediFind, a real-time pharmacy finder, runs on the same serverless discipline.

Before this, I spent a year inside GCB Bank PLC's digital operations: debugging live banking platforms, routing support tickets, and learning what production actually demands when the stakes are real money.

Open to remote Cloud Native, AWS Serverless, and Full Stack roles, anywhere.

SHEET 02 / STACK

Six layers,
one system.

Every layer picked for what the workload actually needs, top to bottom, request to response.

L01

Interface

Interfaces wired straight into serverless APIs, fast by default, no unnecessary client weight.

Next.js React TypeScript Tailwind CSS

L02

Compute & API

Event-driven compute. Nothing runs until something happens; requests are authenticated and throttled at the edge.

API Gateway Lambda Node.js Python Express

L03

Messaging

The glue between services. Queues absorb load spikes, topics fan out alerts to whoever needs them.

SQS SNS

L04

Data

NoSQL for access patterns that need speed at scale, relational where consistency matters more than throughput.

DynamoDB PostgreSQL MongoDB Prisma

L05

Security & IAM

Auth on every endpoint, no secrets in the client bundle, access scoped to exactly what each role needs.

Cognito / JWT Least-privilege IAM

L06

Platform & Tooling

Infrastructure defined as code, versioned in Git, and shipped through CI/CD rather than clicked together by hand.

SAM / CloudFormation Git GitHub Actions Docker

SHEET 03 / LOG

Where the hours
actually went.

Real time in a regulated, high-stakes environment, plus the cloud training and coursework underneath it.

2026

AWS re/Start Programme

AmaliTech CLOUD TRAINING KUMASI, GHANA

Completed AmaliTech's AWS re/Start programme: structured, hands-on labs across the core AWS surface rather than tutorial-only theory.
Built and tore down real infrastructure on EC2, RDS, S3, Lambda, CloudFormation, VPC, CloudWatch, and EventBridge.
Came out with the AWS Certified Cloud Practitioner (CLF-C02), the foundation now feeding into AWS Developer Associate (DVA-C02) prep.

IT Support & Banking Operations

GCB Bank PLC NATIONAL SERVICE KUMASI, GHANA

Diagnosed and resolved failures across digital banking platforms, using the same structured debugging workflow software QA runs in production.
Processed high-volume transactional data across internal CRM and Excel systems, zero data errors across daily operations.
Generated operational reports that fed directly into branch-level decisions.
Got a close look at how enterprise software behaves under real production load: uptime pressure, security protocols, and users who don't care why something broke.

BSc Computer Science

Kwame Nkrumah University of Science and Technology 2ND CLASS UPPER

Graduated with Second Class Upper Honours in Computer Science.
Built a Grade A AI-integrated DeFi platform as a final year project: React front end, Solidity contracts, and a two-layer LSTM model for financial prediction.
Core coursework: Computer Networks, Software Engineering, Database Systems, Operating Systems, Algorithms.

SHEET 04 / BUILDS

Four builds,
shipped and standing.

Serverless, event-driven systems shipped end-to-end on AWS. Real architecture, real code, real deployments.

FLAGSHIP · EVENT-DRIVEN

SentryNode Fraud Engine

An event-driven fraud detection engine that watches transactions in real time. API Gateway receives the event, SQS absorbs the load, Lambda scores the risk, DynamoDB holds the state, SNS fires the alert. Built end-to-end on AWS SAM with a Next.js frontend on Amplify. Least-privilege IAM is the active next step.
