Sr. Backend Engineer, Liquidity

Currently part of the Payments and Liquidity team at LeafLink, responsible for automated credit policy decisions, credit limit management, and credit risk monitoring. I am also responsible for the development of the company's event-driven microservice architecture based on Python Django and Flask running on Kubernetes in AWS. As well as the development of the company's internal data pipelines using Apache Airflow and Redshift.

As a senior member of the team my primary responsibilities include ensuring best practices and code quality, leading technical initiatives, and both product and cross-team collaboration.

Back-End Engineering Lead

Backend engineering lead at a small organization came with a wide variety of challenges and responsibilities from maintenance, debugging, reviews, planning, and design to client troubleshooting and PeopleOps.

Some major initiatives I lead were the migration to an event-driven architecture using Kafka, in place of many RESTful synchronous API calls, migrating multiple APIs requiring advanced search capability to Elasticsearch from Mongo, rewriting multiple legacy PHP-based APIs to Go, migrating all applications to Kubernetes, starting the transition to infrastructure as code (IaaC) using Terraform, and the development of a scalable Websocket API with both realtime filtering and historical search capability for News.

My DevOps responsibilities included managing all cloud infrastructure including Kubernetes clusters running on Digital Ocean, GCP GKE and AWS EKS, SQL & NoSQL databases, implementing alerting, monitoring and observability using Datadog, Prometheus and Grafana, promoting security using OpenVPN & Wireguard along with Cloudflare Access and improving overall systems reliability by using data from observability for both manual and automatic scaling along with some technical migrations such as moving to AWS RDS Aurora.
