Software Development

Design, code, and implement full-stack software solutions using .NET Core (backend/APIs) and TypeScript-based ReactJS/Next.js (frontend). Develop high-quality, scalable, and maintainable applications end to end.

Technical Design and Architecture

Collaborate with architects and senior engineers to define technical vision, system architecture, and integration of AWS services and frontend frameworks. Contribute to the design of software components, ensuring scalability, performance, and adherence to best practices — including serverless-first patterns where appropriate.

AWS Services Integration

Utilize AWS services such as DynamoDB, EventBridge, Lambda, S3, and others to design and implement robust, efficient, serverless solutions. Integrate applications with these services, ensuring optimal performance, scalability, and cost efficiency.

Frontend Engineering

Build responsive, performant, type-safe user interfaces with TypeScript, React, and Next.js (SSR/SSG, App Router, API routes). Ensure clean integration between frontend applications and .NET Core/serverless backends.

Database Integration

Design and optimize database schemas and queries for efficient data storage and retrieval in DynamoDB. Integrate and synchronize data across databases and AWS services.

Testing and Quality Assurance

Write unit and integration tests, conduct code reviews, and enforce coding standards across backend and frontend code. Build and maintain automated test coverage. Collaborate with QA teams to identify and resolve issues.

CI/CD and DevOps

Build and maintain GitLab CI pipelines for automated build, test, and deployment across environments, supporting serverless deployments (Lambda, S3, CloudFormation/CDK/Serverless Framework).

Continuous Improvement

Stay current with .NET Core, TypeScript, React/Next.js, AWS, and AI-assisted development tooling. Identify opportunities for process improvement, code optimization, and enhanced developer workflows — including adopting AI coding assistants to boost team velocity and code quality.

Collaboration and Leadership

Work closely with product managers, designers, and engineers to align development efforts with requirements. Provide technical leadership, mentorship, and guidance to junior engineers across both backend and frontend disciplines.

Troubleshooting and Support

Investigate and resolve complex technical issues in development and production. Support end users/clients to ensure smooth operation of applications.
