Experienced modernizing Rails monolith applications into scalable service-oriented architectures, building Go microservices, designing asynchronous workflows, and operating high-availability backend systems using PostgreSQL, Redis, Kafka, RabbitMQ, Kubernetes, and cloud platforms.

Strong background in backend architecture, REST APIs, GraphQL, gRPC services, automated testing, CI/CD pipelines, observability, production support, and AI-assisted software development workflows.

Senior Backend Engineer at Apex Systems (2022-01 – 2026)

• Designed and developed high-scale backend platforms using Ruby on Rails and Go, building production microservices, internal APIs, and distributed services supporting complex operational workflows.
• Led modernization initiatives migrating Rails monolithic applications toward service-oriented architectures by extracting Go microservices, defining API contracts, and maintaining backward compatibility between systems.
• Built backend services using Go, Ruby, PostgreSQL, Redis, Kafka, RabbitMQ, and NATS, implementing asynchronous processing, event-driven workflows, and reliable communication patterns between services.
• Developed REST APIs, GraphQL APIs, and gRPC services while improving database performance through PostgreSQL schema optimization, query tuning, indexing strategies, and Redis caching.
• Improved engineering reliability through Docker, Kubernetes, Terraform, ArgoCD, CI/CD automation, and observability solutions including Datadog, Prometheus, Grafana, and centralized logging.
• Mentored engineers through architecture reviews, code reviews, testing practices using RSpec, Minitest, Go testing frameworks, and promoted AI-assisted development workflows to improve productivity.

Software Engineer at Cvent (2018-07 – 2021-12)

• Developed scalable backend applications using Ruby on Rails and Python, creating business services, automation systems, REST APIs, and database-driven applications.
• Built Rails backend features using ActiveRecord, Sidekiq, Redis, PostgreSQL, and MySQL while implementing background processing, scheduled jobs, and asynchronous workflows.
• Developed Python services using Django, Flask, and FastAPI for data processing, automation, integrations, and backend functionality supporting enterprise applications.
• Designed and integrated external APIs using REST and GraphQL patterns while implementing secure authentication, authorization, validation, and reliable third-party integrations.
• Improved application quality through automated testing with RSpec, PyTest, Minitest, integration testing, debugging, and performance optimization.
• Supported production systems using Docker, AWS, CI/CD pipelines, monitoring tools, and Agile/Scrum practices while collaborating with product managers and engineering teams.

Backend Software Engineer at MicroStrategy (2015-09 – 2018-05)

• Developed enterprise backend applications using Ruby on Rails and Java, creating maintainable services, APIs, and business logic for customer-facing and internal platforms.
• Built Java backend components using Spring Boot, REST services, SQL databases, and object-oriented design principles while integrating Ruby on Rails applications with enterprise systems.
• Developed Rails applications using MVC architecture, ActiveRecord, PostgreSQL, MySQL, Redis, Sidekiq, and automated testing frameworks including RSpec.
• Implemented API integrations, authentication systems, background processing workflows, and database optimization strategies to improve application performance.
• Containerized applications using Docker and supported deployments through CI/CD pipelines, cloud infrastructure, and production monitoring solutions.
