Tyler Lachance

I’m a senior full-stack software engineer with 8+ years building scalable SaaS, e-commerce, and enterprise platforms. I bring deep expertise across React/TypeScript and Node.js backends, plus Go and Python services, with cloud architecture on AWS/GCP, Docker/Kubernetes, and microservices—paired with a strong focus on performance, reliability, and mentoring teams to ship high-quality software.

Most recently, I led a global admissions platform using React/Next.js and Node.js, creating reusable UI components and dashboards while improving efficiency with TailwindCSS, shadcn/ui, and Storybook. I built Python/Django/Celery services for admissions workflows and delivered RAG and LLM-powered features with LangChain that cut manual response times by 60%, while boosting frontend performance and SEO with SSR/static optimization in Next.js to achieve 95+ Lighthouse scores. Earlier, at Deloitte I modernized legacy systems with Angular/React (20% user experience lift), designed AWS/GCP architectures with Docker/Kubernetes (30% infrastructure cost reduction), and improved API interoperability with REST/GraphQL (40%); at CVS Health, I scaled full-stack healthcare applications for 500k+ patients and providers, implemented HIPAA-compliant systems, and used RabbitMQ to reduce inter-service latency by ~30%.
