Work History
Senior Software Engineer
Perficient
09.2023 - Current
- Led full-stack feature design for large-scale SaaS platforms, integrating modern web frameworks and AI-driven services across distributed systems.
- Architected a Next.js 13 + Node.js platform with modular routing and API composition using GraphQL, improving page rendering times and client performance by over 40%.
- Refined backend APIs with TypeScript and Express, introducing layered validation, caching via Redis, and asynchronous task queues with BullMQ.
- Designed scalable infrastructure with Docker, Kubernetes, and AWS ECS, applying IaC via Terraform for repeatable deployments across staging and production.
- Integrated LLM embeddings using OpenAI and Pinecone for semantic document search and contextual recommendations, encapsulated via internal microservices.
- Improved observability by implementing OpenTelemetry tracing and structured logs through AWS CloudWatch, simplifying root cause analysis and latency tracking.
- Created build pipelines in GitHub Actions, orchestrating automated tests and deployments across multi-environment workflows.
- Extended front-end systems with React Server Components and server actions for real-time data revalidation using Next.js App Router.
- Designed database schemas in PostgreSQL, optimizing query performance through indexing and efficient transaction boundaries.
- Collaborated with product teams to design accessible UI states and server-rendered transitions that minimize layout shifts and hydrate seamlessly.
- Migrated legacy services from REST to a consolidated GraphQL gateway, simplifying schema management and API documentation.
- Partnered with DevOps to enforce container security and runtime isolation through minimal base images and vulnerability scans.
- Mentored three engineers on advanced TypeScript patterns and architectural practices across monorepos and micro-frontend integration.

01.2021 - 06.2023
- Contributed to healthcare SaaS applications focusing on secure data management, patient scheduling, and clinical dashboards.
- Designed distributed backend modules in Node.js with NestJS, handling asynchronous data ingestion from multiple hospital APIs.
- Implemented strict RBAC and JWT-based authentication compliant with HIPAA standards for user sessions and audit tracking.
- Integrated healthcare data models using FHIR and HL7 standards, normalizing disparate datasets into a unified schema.
- Built an internal admin dashboard using React 17 and Material-UI, enabling clinicians to monitor patient outcomes and alerts in real time.
- Utilized PostgreSQL for relational data and Elasticsearch for full-text search over patient records, optimized through field mapping and caching layers.
- Automated CI/CD pipelines using Jenkins and Docker, with staging previews deployed to AWS ECS via blue-green strategies.
- Refactored service code to adopt dependency injection and modular repositories, significantly improving testability and runtime isolation.
- Created telemetry collectors using Prometheus and Grafana, visualizing service load and latency trends.
- Partnered with a cross-functional healthcare analytics team to design ETL processes that processed millions of event logs daily.
Software Engineer
Google
10.2017 - 12.2020
- Worked on data-intensive web services within a high-traffic analytics platform, emphasizing scalability, service mesh integration, and frontend cohesion.
- Designed microservices in Go and Node.js, exposing internal APIs over gRPC and REST within Google's service mesh.
- Contributed to a React 16-based internal dashboard visualizing key usage metrics across multi-region clusters.
- Used BigQuery and Pub/Sub pipelines for event aggregation and near-real-time metric generation.
- Enhanced API throughput by introducing asynchronous job scheduling with Redis Streams and connection pooling.
- Migrated several workloads to Kubernetes, optimizing pod resources and deploying via Helm templates.
- Wrote automated end-to-end tests using Jest and Puppeteer, ensuring backward compatibility across component releases.
- Collaborated closely with SRE teams to improve deployment reliability and adopt canary rollout patterns.
