Lead Go Backend Engineer 

I work as a contractor to design backend applications for multiple clients through AdeivaTechnologies: AWS, Go, Python, Apache Kafka, Terraform, Jenkins(CI/CD pipelines)

Backend Engineer -  Contractor

I led efforts to improve the net promoter score of Cadana&#x27;s platform, evolving it from a payroll processing engine into a comprehensive Employer of Record (EOR) solution. This shift empowered companies to seamlessly scale their engineering teams across diverse geographical regions with complete compliance.I leveraged Golang, Lambda, DynamoDB, S3, API Gateway to build a contract management service for employee and contractor agreements directly within the platform, this enabled companies draft legal compliant contracts.I led the design and development of a robust multi-tenant permissions service within the Cadana platform, facilitating granular access control and tiered user privileges.In order to improve platform observability I used Go and AWS SQS to build a custom metrics collection library. It was utilised by all API workflows across microservices in production. The metrics were pushed to AWS Cloudwatch which visualised API performance providing comprehensive insights into API request handler behaviours.I used Go, and SQS to develop a library that categorises errors according to severity and send the alerts to PagerDuty this streamlined on-call processes for the backend infrastructure.I enhanced API security by developing a custom rate limiting library as part of the API payment gateway&#x27;s authentication flow. This Go service prevents unauthorised transactions of malicious actors.Technologies: Go, AWS (EC2 and Lambda for compute, DynamoDB as the database, SNS for pub/sub, Kinesis for streaming data, Cloudformation for Infrastructure as Code, Cognito for Authentication and Authorization)

Go Backend Engineer

I led the design and development of the fulfilment platform&#x27;s web UI using Typescript, Javascript, React and Tailwind CSS styled components.I I re-designed the UI to prioritise mobile access. This empowered fulfilment personnel to complete orders efficiently on the go.I Collaborated with the backend team to design and implement a GraphQL API using Apollo GraphQL and Node.js. This implementation facilitated seamless data exchange, allowing the creation of near real-time dashboards powered by React and Chart.js. These dashboards empowered hub managers to visualise key metrics and make informed decisions regarding cost reduction and revenue growth.

Software Engineer

I led a team of 3 engineers in designing and building early versions of both the travel experience discovery service and the booking service.I led in requirement gathering, authored the design document for the booking and discovery microservices, and designed the AWS backend infrastructure provisioning it using Terraform.I architected and developed a travel experience discovery service u and booking microservice written using Go, Go-chi, Kafka and PostgreSQL. I developed a custom event-sourcing library in Go leveraging Kafka for streamlined communication between services. I designed the GraphQL schema types representing the data model for the travel experience marketplace.Reduced experience discovery from 4 to 2 steps and booking flow by 4 steps, ultimately boosting bookings by 20% after 3 development cycles and early client testing. Technologies:Go, AWS(Cognito, lambda, API Gateway), AWS RDS(PostgreSQL), Apache Kafka, GraphQL, Jenkins(CI/CD pipelines)

Lead Go Backend Engineer

As part of the Ministry of National Planning&#x27;s census data collection efforts, I joined the data analytics team to build a data collection and analytics platform.I designed and implemented APIs using Python(Django) for data collection and processing exposed via an apache web serverI utilized MySQL for secure and scalable data storage, and integrated Redis for optimized caching performance.I built responsive web based dashboards using Javascript, Typescript, React.js, CSS-in-JS styled components and incorporated interactive business intelligence visualisations powered by Tableau APIs to provide clear and actionable insights into thecollected census data.
