Hi, I’m Olufemi Adesina, a backend-leaning full-stack engineer with 8+ years of experience building scalable, data-heavy systems. I specialise in designing production-grade APIs (Python FastAPI/Django and TypeScript/Node.js/Express), crafting robust PostgreSQL schemas, and architecting microservices and data pipelines across AWS, Azure, and GCP. I routinely leverage Docker, Terraform, and serverless patterns to deliver reliable, high-performance platforms, backed by solid CI/CD practices and comprehensive automated testing. I enjoy working in fast-paced startups, taking ownership of technical decisions, and collaborating with cross-functional teams including data scientists, product leaders, and other developers. I’m motivated by continuous improvement, strong security practices (JWT/RBAC), and enabling delightful, data-driven user experiences through event-driven architectures and AI-enabled features.

Work Experience

Senior Full Stack Engineer / Senior Principal Cloud Engineer at Service Robotics Ltd
May 1, 2022 - November 1, 2025
Architected and deployed scalable cloud infrastructure on AWS with Terraform, supporting data-heavy analytics for thousands of daily users across client organisations. Integrated Kafka-based ingestion into AWS-native pipeline and standardised asynchronous processing (Kafka/Kinesis → SQS → Lambda) with retry Dead Letter Queues, idempotent handlers, and back-pressure controls. Re-architected internal Voice Platform signalling flows using AWS IoT Core pub/sub messaging, migrating from Twilio to Zoom API for a stable, low-latency workflow. Migrated from monolithic EC2 to micro-services (Lambda, ECS/Fargate), improving API response times and enabling independent scaling. Designed automated data pipelines with Lambda scheduling and ACID-compliant ingestion, audit logging in DynamoDB, and full Infrastructure-as-Code via Terraform. Managed PostgreSQL infrastructure with indexing and partitioning for analytics performance; established CI/CD pipelines with GitHub Actions; built FastAPI servi
Full-Stack Developer at Firemind Ltd
August 1, 2018 - May 1, 2022
Architected AWS and Azure infrastructure for client engagements using Terraform, provisioning EC2, Lambda, Fargate, RDS, and S3 with security-first configurations. Designed secure Python APIs (FastAPI) and Node.js/Express endpoints with proper contracts, idempotency, pagination, and rate-limiting. Implemented Redis caching (ElastiCache) to stabilise high-traffic endpoints, developed GraphQL APIs consolidating data from multiple services, and built data pipelines/ETL with AWS Redshift for analytics workloads. Managed CI/CD pipelines across multiple client projects, establishing quality gates and automated testing strategies, and mentored junior developers including AWS certification preparation. Worked with PostgreSQL, DynamoDB, and Redis for data storage and caching; delivered robust backend solutions with a strong focus on reliability and security.
