I help companies transform ideas into reliable backend solutions by designing clean backend architectures, developing robust APIs, integrating cloud services, and implementing complex business logic that supports real-world applications.
My expertise includes:
* Backend API development using Node.js, NestJS, Express, and TypeScript
* Designing scalable backend architectures with clean code principles and maintainable structures
* AWS cloud integrations using Lambda, DynamoDB, S3, EC2, Cognito, API Gateway, EventBridge, CloudWatch, SQS, RDS, IVS, and other AWS services to support backend functionality
* Database design, optimization, and performance improvements using PostgreSQL (TypeORM), DynamoDB, and MongoDB
* Authentication and authorization systems using Passport.js, Auth0, and AWS Cognito
* Payment processing and billing workflows using Stripe
* Transactional email integrations using SendGrid
* AI and Large Language Model (LLM) integrations using OpenAI, Azure OpenAI Service, Google Gemini, OpenAI Realtime APIs, and Claude AI
* Building AI-powered features such as conversational assistants, real-time streaming responses, intelligent automation, and AI-driven backend workflows
* Using modern AI development tools such as Cursor AI to improve development speed, debugging, code quality, and technical decision-making
My development approach focuses on:
* Clean and scalable backend architecture
* Security best practices
* High-performance APIs and database optimization
* Reliable cloud integrations
* Maintainable and testable code
* Building systems that can evolve with business needs
I don’t just write code — I build backend systems that are designed to support real users, business growth, and future development needs.
For projects requiring full-cycle development, I can collaborate with trusted frontend developers and DevOps engineers to provide a complete end-to-end solution. I remain your primary backend contact, ensuring clear communication, technical consistency, and smooth collaboration across the project.
If you’re looking for a backend developer who can think architecturally, solve complex technical challenges, leverage modern AI tools, and deliver production-ready solutions, I’d be happy to help bring your project to life.
