Where I've built

7+ years shipping AI platforms, microservices, and full-stack products — from Fortune 500 enterprise to greenfield architecture.

Lead Software Engineer · Sun Life Financial

Nov 2021 – Present

Designed and shipped an LLM-powered call routing and authentication system — a LangGraph state machine on Amazon Bedrock with DynamoDB-backed session persistence — routing 15+ plan categories and lifting self-service containment from 61% to 96%.
Built Go microservices to onboard Interac as a payments vendor, integrating with core record-keeping systems with full audit logging and processing 25,000+ transactions/month.
Productionized MCP integration for dynamic multi-agent tool orchestration with a custom middleware layer enforcing 3-tier authentication (identity, single-factor, multi-factor).
Spearheading on-prem → cloud migration onto Amazon Bedrock AgentCore, deploying agents via AgentCore Gateway and Runtime for fully managed, scalable agentic infrastructure.
Led serverless migration (Lambda, API Gateway, DynamoDB, SQS) processing 200k+ monthly requests with zero customer-impacting incidents and ~30% lower p95 latency.
Automated caller verification in Amazon Connect through multi-Lambda orchestration — Lex intent capture, ANI lookup, and OTP step-up — reducing authentication resolution time by 65%.
Led and mentored a team of 5+ engineers on LLM-based system design, owning the technical roadmap and presenting quarterly AI strategy to senior leadership.

Jan 2021 – Nov 2021

Led monolith-to-microservices re-architecture using event-driven architecture (SQS) built on Node.js/Next.js with TypeScript, enabling independent scaling and deployment of supply-chain services.
Led front-end modernization with Vue 3 + TypeScript, building a Storybook-documented atomic-design component library adopted across 3+ product teams.
Engineered an end-to-end customs compliance microservice using AWS SAM, Lambda, SQS, and S3 with SFTP integration, eliminating a vendor dependency and saving $300K annually.
Established TDD (Jest) and k6 load testing, achieving zero P0 incidents during peak traffic windows.
Hardened integration security by implementing OAuth 2.0 across 10+ carrier integrations, managing token lifecycle across distributed microservices.
