Leading the design and development of an AI agent platform that enables businesses to automate workflows across multiple SaaS systems through intelligent, task-driven agents.

• Owning end-to-end platform architecture, including agent orchestration, LLM integration, and system scalability to reliably handle complex multi-step workflows.
• Building and integrating with external APIs and third-party services to transform fragmented tools into cohesive, automated workflows for end users.
• Driving infrastructure strategy, deployment pipelines, and system performance to support rapid iteration while maintaining reliability, security, and cost efficiency.
• Translating ambiguous business problems into practical AI-driven solutions, shaping both technical direction and product capabilities.

Led company-wide infrastructure strategy and operations, reporting directly to the CEO, with responsibility for cost control, reliability, security, and long-term sustainability of the platform.

• Drove migration from AWS to bare metal infrastructure, taking full ownership of planning, execution, and operational stability to significantly reduce recurring cloud costs.
• Migrated email services from Google Workspace to a self-hosted mail server, balancing cost efficiency with security and operational reliability.
• Designed and implemented a custom monitoring stack using Prometheus and Grafana to provide full visibility into infrastructure health and performance.
• Established routine backup systems for databases and file servers, improving data resilience and disaster recovery readiness.
• Built automation scripts to streamline deployment, maintenance, and operational workflows, reducing manual intervention and operational risk.
• Migrated CI/CD pipelines from Jenkins to GitHub Actions to simplify maintenance and reduce tooling costs.

Founded and lead Zenvoye, a software house delivering end-to-end product development and platform engineering, while remaining hands-on in critical technical decisions and execution.

• Defined technical standards, architecture patterns, and delivery processes for client projects across web, backend, mobile, and infrastructure.
• Acted as principal engineer on high-impact projects, taking ownership of system design, scalability, and deployment strategy.
• Oversaw full project lifecycles from requirement translation and architecture design to deployment and post-launch operations.
• Established CI/CD and deployment best practices to ensure consistent delivery quality across client engagements.
• Balanced client needs, delivery timelines, and technical sustainability as both business owner and technical decision-maker.

Led operation and optimization of containerized infrastructure supporting production workloads, including delivery of AI systems into restricted government environments.

• Ensured high availability and reliability across Kubernetes clusters supporting production workloads.
• Strengthened delivery pipelines and system resilience by improving CI/CD workflows and addressing critical security vulnerabilities across services.
• Delivered AI workloads into restricted government environments, ensuring secure and compliant execution within private infrastructure constraints.
• Improved infrastructure performance and cost efficiency through proactive optimization and system-level enhancements.

Owned platform, infrastructure, and delivery pipelines across web, backend, and mobile products as the primary decision-maker for system architecture, CI/CD standards, and operational practices.

• Migrated production workloads from EC2 to serverless architecture using SST, improving scalability and reducing operational complexity.
• Designed self-hosted GitHub Actions runners and unified CI/CD release workflows across frontend, backend, and mobile teams, enforcing dependency vulnerability checks.
• Built and operated a containerized Laravel backend with PostgreSQL and pgvector to support internal tools and future feature development.
• Led migration from Create React Native App to Expo, implementing fully automated build and release for both App Store and Play Store.
• Minimized public IP exposure and designed private inter-VPC networking for secure internal service communication.
• Implemented centralized monitoring using AWS CloudWatch, enabling early detection of production issues across all services.

Owned and operated platform infrastructure and delivery pipelines for multiple high-traffic products across food & beverage, global marketplace, and e-commerce domains.

• Built internal tooling to accelerate sprint planning and designed a centralized operational request workflow to improve cross-team collaboration and accountability.
• Led company-wide migration from Jenkins to GitHub Actions, reducing CI/CD maintenance overhead and infrastructure cost.
• Optimized AWS cost by migrating workloads to Spot Instances, cleaning up unused services, and running large-scale S3 raw photo cleanup jobs.
• Reduced public IP usage by designing a mesh VPN network between services.
• Built and maintained custom macOS self-hosted runners (Mac Mini) for iOS and Android builds.
• Strengthened security posture by implementing DefectDojo for code security assessment and integrating SonarQube for static analysis.
• Designed AWS infrastructure from scratch for YAY! Group to support multiple brands and high-volume online delivery traffic.
• Migrated Wagginton's source control from Bitbucket to GitHub, including CI/CD pipeline migration and SonarQube integration for code quality governance.

Led a platform optimization initiative to improve system performance and cost efficiency by redesigning the deployment and delivery approach.

• Initiated and executed migration from static infrastructure to an on-demand platform architecture, achieving ~70% performance improvement and ~50% infrastructure cost reduction.
• Adopted an infrastructure model that automatically scaled with demand, eliminating unnecessary always-on resources and reducing operational overhead.
• Established a standardized CI/CD pipeline to improve deployment reliability and reduce manual release effort.
• Built and launched the company landing page to support product presence and early user acquisition.
