Position Summary

We are seeking an experienced Full Stack Developer (5–8 years) to design, build, and maintain scalable frontend and backend systems across multiple domains. You’ll work closely with product, DevOps, and other stakeholders to deliver mission-critical solutions that power our growth.

But beyond just technical chops, we want a go-getter who’s not afraid to jump in, figure things out, and make things happen. You’re scrappy, resourceful, and all about execution — solving problems with creativity, logic, and whatever tools you can get your hands on. You’ve got a solid work ethic, owning your projects end-to-end and stepping up when the heat is on. You’re a self-starter who doesn’t wait for all the answers — you research, learn, and just get it done. Feedback? You take it, grow from it, and come back stronger. Most importantly, you’re a team player with accountability — someone who backs up the crew, takes ownership.

• Integrate applications with cloud platforms (Azure or AWS) and databases (PostgreSQL, MongoDB).
• Ensure application performance, responsiveness, and security across devices.
• Monitor and troubleshoot issues using observability tools (Prometheus, Grafana, ELK Stack).
• 
  

Qualifications

• 5–8 years of professional experience as a Full Stack Developer, delivering production-grade applications.
• Proficiency in JavaScript frameworks (React.js, Next.js) and backend technologies such as Python (FastAPI).
• Strong understanding of REST APIs, microservices architecture, and modern web application design.
• Hands-on experience with relational and non-relational databases (PostgreSQL, MongoDB).
• Exposure to containerization (Docker) and orchestration tools like Kubernetes.
