# Experience

> More than ten years of designing and building software, from internal platforms and cloud architecture to web and mobile apps, for teams in the Philippines, the United States, Japan and Australia.

## Software Architect

Credit management services · United States

- I lead the design and delivery of internal systems, dashboards, API servers and third-party integrations for a growing credit operations platform. Each piece starts as a business need, and I turn it into a system design, a milestone plan and sprint tickets a team can pick up and build.
- I designed a DMZ-based AWS network that keeps internal systems off the public internet. It uses subnets, load balancers, security groups and routing rules, and its Lambda functions reach credit bureau APIs only through approved outbound paths and a domain allowlist.
- I designed, and helped build, a Salesforce data sync platform in Terraform using EventBridge, Lambda, Step Functions, SQS, S3 and RDS. It supports full and delta syncs with layered auditing, and a sync finishes in under 10 minutes.
- I designed the webhook and notification processing for credit bureau integrations. It checks, enriches and stores each alert, then writes it back to Salesforce as a readable record when the team needs it. I also helped deliver the full 30-day credit report workflow on top of it.
- I cut the CI/CD pipelines' run time from 30 minutes to 8. I also added unit tests to them, and built a tool that carries commits from the main repository into its submodules.
- I automated manual work for the operations team and wrote onboarding workbooks for new developers. I also support the team with code reviews, one-on-one mentoring, Git guidance and production deployments.
- I supported the company's SOC 2 Type 2 readiness. I fixed the security findings Drata reported across its GitHub repositories and AWS infrastructure, which cut those findings by 99%.
- I helped set up the company's in-house IT team as leadership moved it toward a fintech operating model.

## Senior Software Developer

Software services, client projects · Philippines (contract)

- I delivered full-stack work across frontend, backend and cloud for client projects, including web platforms and AWS IoT systems.
- I built NestJS modules and tuned the SQL queries and filters for a food booking platform, and delivered its backend requirements in 2 months.
- I made search up to 80% faster on a document-heavy project with better queries and search design. I also added Elasticsearch to improve keyword search across large sets of PDF documents.
- I designed and built an AWS IoT system that deploys small Linux apps to a fleet of Raspberry Pi devices. Each device fetches its schedule and switches its equipment on and off automatically.
- I often took on informal technical leadership, helping teams agree on who does what and clearing blockers between them.

## Interim President, Senior Software Engineer and Full-Stack Developer

Software development company · Philippines

- As Interim President, I worked with stakeholders on budgets, quarterly goals, company documents and policy revisions, and kept the company running through a period of transition.
- As Senior Software Engineer, I designed, built and maintained web and mobile apps for clients. I also deployed, secured and maintained their servers on AWS, Google Cloud and Vultr.
- I led development using Agile, trained junior developers across the whole development cycle, and improved hiring with technical assessments and better development tools.
- As Full-Stack Developer, I built and maintained web and mobile apps, wrote the technical and user documentation, and tested and refined the software against each project's requirements.

## Integration Developer

Agriculture and food distribution · Japan (freelance)

- I built Integromat scenarios that automated manual processes, with asynchronous flows that ran side by side and made processing up to 5 times faster.

## Full-Stack Developer

Education technology · Australia (consulting)

- I created wireframes and mockups from the client's requirements.
- I built an iOS app in Swift, an admin portal in Vue.js, and a REST API with Node.js, Express and MongoDB.
- I ran ad hoc testing and published the app through App Store Connect.

## Automation Developer

Financial markets tooling · United States (freelance)

- I built Puppeteer and Node.js tooling that processed more than 5,000 NASDAQ and NYSE tickers in under 10 minutes.
- I set up the Linux scraping servers that run on a schedule during market hours and calculate technical indicators.

## IT Engineer

Creative and community organisation · Philippines

- I built and maintained internal software, designed and secured the local network, and handled technical support and routine security checks.
