Leading a team of engineers responsible for building and maintaining the payment and subscription infrastructure in a multi-cultural and multi-regional company. I am responsible for building an autonomous, agile, team. This includes hiring, mentoring, conflict resolution, providing strategic and technical direction. I worked directly with the product owner to ensure the priorities match the company’s strategic direction and growth objectives. During a very difficult time in the Cape Town office, I managed to not only retain my team but also grow the team. During this period, I relocated the team to new office space, managed to resolve continuous payroll issues and reworked the hiring process to ensure only quality engineers were hired.

I was part of the engineering team that looked after all things payments at iflix. We enabled users from various emerging markets to pay for iflix using their preferred payment method.We looked after the central subscription-management and order-placement systems, regularly adding new payment-integrations and extending functionality within our external-billers framework to provide new users with payment mechanisms.Our systems have been built as cloud native solutions, making use of Amazon AWS services where possible. Systems were stateless and made heavy use of an event-driven design. These systems spanned both serverless and containerized solutions and were deployed to AWS Lambda and Kubernetes, respectively.The systems had to be scalable considering iflix's goal considering iflix's large user base and rapid expansion, and served millions of requests per hour.One of my first projects in this team was to migrate approximately 11 million users from 3 separate legacy systems into our new wallet platform without any downtime. We succeeded in completing this migration in just a few months, successfully migrating users from multiple regions with many payment mechanisms.Keywords:- AWS (SNS, SQS, DDB, Kinesis, RDS, Cloudformation, S3, API Gateway, Lambda, CloudWatch, etc)- Microservices- Nodejs- PostgreSQL- DynamoDB- Serverless- Kubernetes- Event sourcing

I lead a multicultural, multi-regional team consisting of 5 architects. I managed the execution and measurement of work and provided the team with technical direction. I reported directly to the CTO of the company. I was responsible for mentoring and upskilling not only our software architects but also our software engineers. I was tasked with breaking down an ivory tower structure and destroying any silos that existed between the architects and engineers. By doing this I improved the overall quality of the system, increased the general skill level in the department and promoted transparency and ownership.I assisted in converting our single tenanted systems to multi-tenanted state in order to introduce a secondary store; daily.konga.com. This store was an attempt at selling grocery items online in Nigeria.Assisted with the design and development of supporting warehouse systems to improve the efficiency of inbounding, outbounding and managing stock and inventory in the warehouse. This allowed us to open up the platform for use by 3rd party merchants.Assisted in the design and implementation of a scalable product catalog, search engine, and autosuggest to name a few.

As a software architect, I was given more responsibility for the larger picture. I focused on the design (and development) of service-oriented systems in a complex business domain. I worked directly with Product Owners to define the business needs and translated them into a technical solution that would fit into the overall ecosystem. A lot of emphasizing and focus is applied in attempting to decompose and decouple a set of legacy monolithic systems.I designed and implemented a recommendations systems based on open source technologies saving the company hundreds of thousands on licensing fees. I designed and implemented an gateway solution for the unreliable conditions we faced in the emerging market we were operating in. The system was based on Facebook's GraphQL protocol and acted as an aggregation layer for client applications and systems. It significantly reduced the number of calls and size of responses returned the the clients. This significantly improved the user experience of our mobile and progressive web app clients. This project made it possible for our progressive web app to be featured in Google's Progressive Web App Summit in 2016.Assisted in converting our single tenanted systems to multi-tenanted state in order to introduce a secondary store; daily.konga.com.Assisted with the design and development of supporting warehouse systems, product catalog, search engine, autosuggest to name a few.

I joined as a Software Engineer in the Service Oriented Architecture team. We were tasked with breaking up our Monolithic e-commerce platform, based on Magento, into smaller micro-services hosted in the cloud.As part of the SOA team, I helped establish proper coding standards and refined the code review process. I assisted with the setting up support systems to improve the code quality and developed libraries to aid in the shift to a microservice architecture. I helped in successfully extracting the product catalog, stock management, recommendation, wishlist, autosuggestion and many more.I often found myself moving between DevOps, development and software architecture.Help drive the implementation of Docker containers for standardization of the development environment, allowing developers to easily get started on new projects and providing a consistent development environment.Keywords:- AWS (Opsworks, EC2, S3, RDS, ElastiCache, etc)- Nodejs- Elasticsearch- PredictionIO- Docker- Kubernetes- Redis- Chef- Terraform

At Rightshift we applied gamification to online slot machines. I formed part of the core team responsible for designing, implementing and maintaining a set of microservices that would gamify existing slot machine games. These services were developed in Java with a NoSQL database for persistence. The systems were designed to be multi-tenanted, thus allowing us to easily integrate multiple clients onto the platform.We added concepts like achievements, rewards, and leaderboards to slot games to increase engagement thus increase business revenue.We followed a service-oriented architecture. Implemented event-driven architectures where it made sense. We automated infrastructure provision using Ansible and VMWare.We made heavy use of AMQP for communication between various systems.During my employment at Rightshift, Rightshift was acquired by Derivco. Derivco is a large player in the online gaming industry with a global presence. After being acquired by Derivco, I was selected to be part of a small team who did research and development for the implementation of their central event bus using RabbitMQ.
