API Development: Design, build, and document secure RESTful and GraphQL APIs for internal and external consumption.
Frontend Excellence: Create responsive, accessible, and performant user interfaces that deliver seamless customer experiences across desktop and mobile platforms.
Database Management: Structure, optimize, and maintain relational and non-relational databases (SQL/NoSQL) to ensure data integrity and query efficiency.
DevOps & Delivery: Set up and maintain CI/CD pipelines, containerize applications, and deploy services to cloud environments (AWS/GCP/Azure).
Code Quality & Mentorship: Write clean, testable code with high unit/integration test coverage while participating in peer code reviews and mentoring junior engineers.
Qualifications & Requirements
Experience: 5+ years of professional software engineering experience delivering full-stack production web applications.
Frontend Proficiency: Strong expertise in JavaScript/TypeScript and modern frontend libraries/frameworks (e.g., React, Vue.js, Angular, or Next.js) alongside HTML5/CSS3 and state management.
Backend Mastery: Deep knowledge of backend runtime environments and frameworks (e.g., Node.js/Express, Python/Django/FastAPI, Java/Spring Boot, or Go).
Data Management: Solid understanding of database systems such as PostgreSQL, MySQL, MongoDB, or Redis, including query optimization and schema design.
Cloud & DevOps: Hands-on experience with cloud platforms (AWS, GCP, or Azure), Docker containers, Kubernetes, and CI/CD automation tools.
Core Fundamentals: Strong grasp of web security best practices (OWASP), asynchronous programming, system design, and software architecture patterns.
Preferred Qualifications
Experience with serverless architectures, event-driven systems (Kafka/RabbitMQ), or microservices.
Knowledge of web performance monitoring, logging tools (Datadog, Splunk), and automated testing frameworks (Jest, Cypress, Playwright).
Experience working in an Agile/Scrum development environment.
