Led reconstruction of the engineering group after the contentious departure of the initial technology founders. The business was highly skeptical of technology and needed to see significant milestones achieved before entirely agreeing to the new vision.Oversaw 12 concurrent software development projects: core system development, distinct integrations with 4 corporate partners, 3 customer-specific implementations, and unique builds for 2 joint venture partners and 2 external system integration partners.Created corporate technology vision and road map to support and drive business strategy. Created a complete technology budget (staff, infrastructure, capital expenditures) and closely monitored spending to ensure technology maintained a strong return on investment.Rebuilt the technology department from the ground up: hired development and IT staff and updated product development processes using modern frameworks like Agile and CI/CD to drive engagement with the business and create achievable deliverables.Built real-time pricing and calculation engine in C++ for revolving credit accounts and Rust for real-time data processing. Added Jenkins and reengineered Kubernetes clustering infrastructure for deployments.Leveraged AWS by redesigning internal VPC and adding new services, including Aurora, ELB, Cloud Watch, EC2, Route 53, Fargate, S3, and Lambda.
