Software engineer. I build full-stack systems in TypeScript and JavaScript, run them on AWS, and put AI into production with tests and a person still approving what goes live.

Python. Architecture review, delivery governance, and quality standards for Python backend teams. Personal coding on Python has been limited.
JavaScript. Hands-on production work in TypeScript, React, Next.js, Vue, Node.js, Express, GraphQL, and REST. Redux is part of that React stack.
AWS. Platforms delivered on EC2, Lambda, EKS, API Gateway, S3, RDS, VPC, CloudWatch, and SNS, with Terraform, CloudFormation, and AWS CDK. Blue/green and canary releases. AWS Certified Solutions Architect – Professional is in progress.
AI. Production systems on OpenAI, Amazon Bedrock, and LangChain that retrieve context, choose a next step, and call tools: an SOP knowledge assistant, a customer-support copilot with human review, and an event-driven operations workflow. Support information lookup fell by as much as 60–90%. I also set how GitHub Copilot, Cursor, and Claude Code enter an engineering SDLC, including MCP integrations and review of model-generated changes.
- Multi-tenant SaaS with more than 10 million active users. NPS moved from about 60% to about 85%, with about 40% less time in key workflows.
- Internal operations platform for a product with about 500K monthly active users, including the three production AI systems above.
- Data platform moved to Snowflake across 3,000+ PostgreSQL tables: about 10× reporting speed and about 40% lower infrastructure cost. Reporting built with SQL and dbt.
- Healthcare workforce platform with HIPAA-oriented access controls, audit logging, and protected APIs.
- Engineering organizations from zero to about 10 people, and later up to 50+ engineers across eight pods.
| Technology | Capacity |
|---|---|
| TypeScript, JavaScript | Production applications across several companies |
| Node.js, Express | APIs, internal platforms, and production troubleshooting |
| React, Next.js | Full-stack product work, including data-dense screens |
| Vue | Internal operations applications, including tables, filters, and dashboards |
| GraphQL, REST | APIs on PostgreSQL, MySQL, and MongoDB |
| PostgreSQL, MySQL, MongoDB | Application data stores. PostgreSQL at 3,000+ transactional tables |
| SQL, dbt, Snowflake | Reporting system on PostgreSQL and Snowflake |
| AWS: EC2, Lambda, EKS, API Gateway, S3, RDS, VPC, CloudWatch, SNS | Platforms delivered on this set |
| Docker | With those AWS deployments |
| Azure | Delivery on Azure alongside AWS |
| Jest, Mocha, Cypress | Automated tests on internal platforms |
| Technology | Capacity |
|---|---|
| Terraform, CloudFormation, AWS CDK | Infrastructure as code, blue/green deployments, canary releases |
| Kubernetes (EKS), GCP | Delivery on EKS and on GCP |
| GitHub Actions, Bitbucket Pipelines, CircleCI, Jenkins | CI/CD and release governance |
| CloudWatch, Datadog, Sentry | Observability: logging, metrics, alerting, tracing |
| OpenAI, Amazon Bedrock, LangChain | Designed and governed the production AI systems, including RAG, structured outputs, tool calling, evaluation, and human review |
| GitHub Copilot, Cursor, Claude Code, MCP | Daily engineering rollout, with rules, review gates, and SDLC vetting |
| RBAC, audit logging, protected APIs | HIPAA-oriented and SOC2-oriented controls for PII |
Personal coding on these stacks has been limited. The work was architecture review, delivery governance, and quality standards.
| Technology | Capacity |
|---|---|
| Python | Led Python backend teams at that altitude |
| Go | Same altitude as Python |
| .NET | Led .NET backend teams at that altitude |
These are part of the platform expertise. The role notes do not describe a separate hands-on delivery story for each one.
