Debug complex technical issues across the stack and improve performance and reliability. Contribute to architecture decisions, code reviews, and mentoring as the team grows. Requirements: 4 years of experience in software development, with hands-on full-stack experience (React or React Native .NET Core). Proven experience building consumer-facing features (B2C, gaming, e-commerce, or social platforms preferred). Strong understanding of API design, backend architecture, and cloud environments. Practical experience with mobile development (React Native or native mobile). Comfort with rapid prototyping, working iteratively, and adapting to changing priorities. Ability to handle both feature implementation and DevOps/infrastructure tasks when needed. Excellent problem-solving, debugging, and communication skills. Nice to have: Experience with machine learning algorithms or recommendation systems. Experience with GraphQL. Familiarity with feature flagging, experimentation frameworks, or A/B testing.
