Current Focus
Having co-founded a SaaS startup and advised over 200 clients globally across Singapore, Europe, Africa, and the Americas, I don't look at systems in isolation. My engineering decisions are driven by time-to-market, budget boundaries, and client communication—skills honed through years of technical sales, team leadership, and public auditorium workshops.

Designing secure, VPC-isolated cloud environments and integrations that enable enterprise organizations to leverage Large Language Models (LLMs) safely within regulated frameworks.
Establishing guardrails and compliance pipelines to ensure large-scale, multi-account infrastructures conform strictly to HIPAA, NIST, and FISMA compliance models.
Automating software delivery pipelines, provisioning secure multi-account environments, and integrating compliance-as-code guardrails to embed security into the development lifecycle.
Translating ambiguous business requirements and founder visions into scalable solution designs, scoping cloud budgets, and serving as a primary advisor throughout project lifecycles.
Over a decade of cloud engineering and architecture leadership
At Xpertech, I lead the design and delivery of secure cloud platforms for healthcare, research, and enterprise organizations, working directly with technical leaders, researchers, and executive stakeholders. My role extends beyond cloud architecture—I participate in solution discovery, translate business requirements into technical designs, guide engineering teams, and oversee projects from initial discussions through production deployment.
My role initially focused on engineering and cloud operations before gradually evolving into solution architecture. During this period I was responsible for modernizing legacy platforms, building serverless architectures, operating production AWS infrastructure, and supporting healthcare research initiatives.
Built an independent consulting practice focused on helping startups transform business ideas into production-ready software. Unlike traditional freelance development, my work involved understanding customer problems, designing technical solutions, and delivering complete systems from concept through production.
Zixana was my first experience building a technology business from the ground up. As a co-founder, I wasn't responsible only for technology—I was responsible for understanding customer problems, designing solutions, building the product, supporting customers, and growing the business.
Real-world systems delivering scalability, compliance, and impact
Migrated 20+ Years environmental sensors and camera telemetry into S3. Built Lambda/Step Functions pipelines for time-lapse video generation and metadata ingestion, reducing admin overhead by 40%.
Standardized AWS organizations using Control Tower, custom Service Catalog items, and automated compliance policies matching HIPAA and NIST 800-53 controls for ACTRI, UCSD Health, UCR, and UCI-Hub.
Implemented HIPAA Config Conformance Packs, private package repositories (RCRAN/PyPI) inside secure boundaries, AD password reset application, and secure cross-account SFTP transfers.
Designed management, audit, and log accounts enabling disposable student sandboxes with consolidated billing, applying AWS SCP policies as budget guardrails and Lambda for lifecycle automation.
Managed AWS infrastructure supporting 40+ research and public websites. Implemented WAF protection, cross-account backup automation, and permission control with a Windows Bastion application.
Constructed a serverless system in Python following Domain-Driven Design (DDD) patterns. Synced real-time physical telemetry streams (Fitbit API) and authenticated clinical users using EPIC FHIR tokens.
Contributed to a Django-based mental health application for UCSD students. Configured secure database interactions, REST API endpoints, and scheduling modules for clinician coordination.
Coordinated Next.js generative AI application for UCSD Health safety event tracking, implementing secure Cognito user directories and on-premise Active Directory SSO access management.
Directed AWS deployment of a public research repository, coordinating the software development lifecycle for custom elasticsearch modules and coordinate heatmap visualization features.
Oversaw the timeline and development of a custom search and analytics backend, integrating with the Qualtrics API to ingest, structure, and query qualitative research survey response datasets.
Programmed interactive metrics reporting panels using RShiny and set up secure supporting AWS infrastructures to serve dashboards to healthcare program research coordinates.
