Taproot Solutions Inc, Remote (IT)

-Architected greenfield SaaS platform using React, NestJS, and TypeScript, establishing scalable service boundaries, API contracts, and frontend component standards across distributed engineering teams.
-Integrated LLM workflows using LangChain, OpenAI API, and Anthropic Claude into production Healthcare features,enabling AI-assisted document processing and intelligent user interaction at throughput.
-Built event-driven microservices using Kafka and RabbitMQ on AWS ECS, improving system resilience and decoupling FinTech transaction processing from synchronous API response dependencies.
-Deployed Kubernetes-orchestrated Node.js services with Terraform and AWS Lambda, establishing infrastructure-ascode standards and reducing environment inconsistency across staging and production releases.
-Implemented GraphQL Apollo federation layer across Healthcare platform services, reducing over-fetching, improving query performance, and standardising data access for React frontend consumers.
-Established Jest and Playwright testing standards across frontend and backend codebases, raising coverage quality and reducing post-deployment defect rates on critical SaaS platform workflows.
-Engineered RAG pipeline features using pgvector and LangGraph, enabling semantic search and contextual retrieval across Healthcare document collections within production application workflows.
-Mentored mid-level engineers through architecture walkthroughs, code reviews, and AI-assisted development workshops using Cursor AI IDE and Claude Code tooling across the team.
-Collaborated with product, design, and operations stakeholders to translate complex requirements into phased delivery milestones, maintaining implementation clarity during high-pressure SaaS release cycles.
