About this gig

Need a web app that's fast, secure and built to scale? I'm a full-stack software engineer who builds production systems every day at a cybersecurity company, and I bring the same standards to your project.

What I build:

  • Full-stack web apps with React + Spring Boot
  • REST APIs with secure authentication (JWT/OAuth)
  • PostgreSQL database design and optimization
  • Admin dashboards and SaaS MVPs
  • AI features: chatbots, smart search, LLM integrations
  • Docker, CI/CD and AWS deployment

Why work with me:

  • Clean, well-structured code that you fully own
  • Responsive, modern UI on every device
  • Regular progress updates throughout the project
  • Production mindset: security, performance and scalability from day one

Tech stack: React, Java, Spring Boot, PostgreSQL, Redis, Kafka, Docker, Kubernetes, AWS

SDE 2 at a large multinational tech company (promoted within a year). I build complete products end to end: frontend, backend, database, deployment, and monitoring, owned by one engineer from idea to launch. Frontend: React, React Native, TypeScript. Backend: Spring Boot / Java (and Python), PostgreSQL, Kafka, Redis. Infra: Docker, Kubernetes, AWS, Ansible, CI/CD, plus monitoring with Grafana, Prometheus and OpenSearch/ELK. I also build and integrate custom chatbots. My focus is software engineering and product delivery, not AI/ML modeling. Chatbot builds and integrations are in scope.
