I help startups and growing companies build scalable backend systems, cloud infrastructure, and high-performance applications that can support real-world growth.
Over the last 4+ years, I've designed and delivered backend platforms across fintech, healthcare, transportation, gaming, e-commerce, and enterprise systems. My work ranges from building products from scratch to modernizing and scaling existing platforms that struggle with performance, reliability, and maintainability.
Clients typically bring me in when:
• They need a senior engineer to design and build a scalable backend
• Their application is growing, and the architecture needs to scale
• Performance bottlenecks are impacting users and business operations
• They need to migrate from a monolithic application to microservices
• They need reliable cloud infrastructure and deployment automation
• They need an experienced engineer who can take ownership and deliver
Recent projects include:
• Building a healthcare transportation platform serving transportation providers and healthcare organizations across the United States
• Developing a large-scale crypto gaming platform with real-time events, payment processing, rewards systems, and high-concurrency workloads
• Designing and implementing payment gateway and merchant integration platforms
• Building taxi-hailing and transportation management systems
• Deploying and maintaining cloud-native applications using modern DevOps practices
Core expertise:
Backend Development
• NestJs / Express
• TypeScript / Node.js / NestJS
• REST APIs, gRPC
• Microservices & Distributed Systems
Cloud & DevOps
• AWS, GCP, Azure, DigitalOcean
• Docker, Kubernetes
• CI/CD Pipelines
• Infrastructure Automation
Databases & Messaging
• PostgreSQL, CockroachDB, MongoDB
• Redis
• Kafka
• Google Cloud Pub/Sub
What clients value most about working with me:
• Strong ownership and accountability
• Clear and proactive communication
• Clean, maintainable, and scalable code
• Business-focused engineering decisions
• Ability to quickly understand complex systems and deliver results
If you're looking for an engineer who can design, build, optimize, and scale production systems while making sound architectural decisions, I'd be happy to discuss your project.

As a Full-Stack Engineer turned ServiceNow Developer, I bring a software engineering mindset to the platform. I build custom applications and deep integrations that go way beyond basic configuration.
While many can handle basic administration, I bring an architectural mindset to ServiceNow. Having engineered external systems that scale to 1M+ users, I apply that same rigor to your instance to ensure it is scalable, clean, and custom-fit for your business.
Why I’m a different kind of developer:
✅ Engineering DNA: I build Scoped Apps and UI Builder workspaces with the precision and logic of a React/Node.js developer.
✅Integration Specialist: I thrive on complex Scripted REST APIs, connecting ServiceNow to your entire tech stack seamlessly.
✅Code Quality: I write performant GlideScript and TypeScript designed to solve problems today without creating technical debt tomorrow.
✅Process Driven: I bridge the gap between "out-of-the-box" limitations and your actual business requirements.
I dedicate myself to one major project at a time to ensure your architecture gets my full focus. If you need a developer who thinks like an architect, let’s connect!
