• Led a matrixed global team of 150+ software engineers in optimizing cloud and infrastructure costs, defining a data engineering (AI/ML) strategy, reducing the number of significant customer impacting events, and developing an integrated product development roadmap. • Led through an organizational restructuring followed by a significant lean optimization.• Prepped organization for exit via acquisitionKey Accomplishments• Reduced AWS cloud expenditure by 25% ($1.4M on a spend of $5.6M) and reduced overall annualized engineering expenditure by 45% ($4.5M on a spend of $10M) within two quarters.• Developed and executed a strategy to migrate legacy monolithic Python 2 codebase to Python 3 while extracting core functionality into Go and TypeScript microservices.• Developed and executed a strategy to migrate from manual testing to modern continuous integration and continuous deployment (CI/CD) paradigms.• Automated production microservice deployment pipelines through infrastructure-as-code scaffolding.Delivered Kotlin and Swift mobile order taker and contactless mobile payment taker applications.

• Transformed EngOps and DevOps models from “over the wall” to “owner-operator,” requiring intensive training funded through AWS’s Learn to Earn program for VC backed companies. • Realigned engineering organization into functional verticals that delineated responsibilities, and shaped thought leadership by introducing mental models, design documents, and design reviews. • Partnered with HR to introduce clear career progression ladders, market competitive compensation bands, and annual reviews featuring SMART goal setting/tracking. • Led engineering organization through multiple rounds of lean optimizations, C-suite leadership changes, and significant periods of financial uncertainty.Key Accomplishments• Achieved annualized 50% ($2M) reduction in cloud costs by developing cloud infrastructure and third-party vendor relationships.• Contributed net annual savings of 35% ($1.5M) by championing and delivering the re-platforming of monolithic system architecture to containerized microservices utilizing AWS Lambda, AWS ECS, MongoDB, Graph QL, and Terraform, in addition to retiring platforms.• Led 25% of engineers to becoming AWS certified, achieved 75% reduction in incident mean time to recovery, and had 100% of engineers joining on-call rotations, with zero loss of engineering velocity.

• Built and led an organization of 300+ engineers across several diverse product engineering verticals, including: Grab for Business, real-time communication platforms (AI chatbots, VOIP, SMS), marketing segmentation platforms, automated customer care platforms, mobile build and test platforms, core microservice/application framework platforms, and developer experience platforms. • Drove AWS/Azure multi-cloud strategy and negotiated significant discounts on services through AWS’s enterprise discount program (EDP/PPA). • Operationalized a 400-person (5%) reduction in force during fund-raising headwinds and a 70% loss of transactions due to COVID lockdowns in Southeast Asia.Key Accomplishments• Introduced stability-enhancing operational excellence processes including postmortem reviews, action item tracking, root cause analysis, and mitigation strategies across Grab and its subsidiaries to lower customer impacting incidents and mean time to recovery by over 50%.• Cut annualized AWS and cloud infrastructure costs by 60% ($100M).• Reduced software vulnerabilities over 50% by partnering with Grab’s CISO to launch an operating system engineering organization, introduce standard build practices, and reduce reliance on inherited legacy third party packages.• Chartered a FinOps organization to capture, store, and track cloud costs empowering showback, chargeback, and assigned spend budgets features in addition to alerting, alarming, and campaign management capabilities.• Launched GrabMart, delivering convenience items on demand in response to COVID lockdowns and decreased freedom of movement.

• Led an 85+ person organization responsible for product definition, architecture, and delivery of massive-scale service-oriented platforms supporting five verticals: Catalog Services, Front End Services, Amazon Device Services (First Party), Third Party Device Services, and Speech Platform Services. • Built Alexa Video’s engineering and operational culture, worked across Alexa’s ecosystem to influence product roadmaps, and drove AI/ML requirements.Key Accomplishments• Launched the Echo Show, an industry unprecedented voice-forward, screen-based Alexa-powered user experience complete with a catalog of over 5 million titles of content including live broadcasts.• Spearheaded and launched support for Netflix, Hulu, HBO, and over 50 streaming and cable providers on the Alexa Video platform across a population of over 50 million+ global end users. • Launched internationalization capabilities of Alexa Video into Asia and Australia/New Zealand.

• Directed a 70-person organization across four geographies (Seattle, N. Virginia, Dublin, and Sydney) managing end-to-end delivery of the RDS console control plane and operational services. • Delivered increased scalability, elasticity, and availability in support of a business driving $3B+ in annual revenue and multiple millions of database instances worldwide. • Led senior executive business reviews, contributing thought leadership on subject matter such as architecture, strategy, operational excellence, and deployment automation.Key Accomplishments• Championed and built an AWS Database Services presence in Sydney, Australia from the ground up, as the AWS customer base began demanding 24x7 English-speaking support for critical workloads.• Led global launch operationalization strategy, planning, and execution for RDS Aurora and Data Migration Service (DMS).• Built a 12-member TS-SCI cleared engineering team to construct, implement, operationalize, and provide ongoing SCIF support for an air-gapped AWS cloud supporting C2S.
