I'm a Senior Full-Stack Software Engineer with 14+ years of experience building scalable software that solves real business problems. Throughout my career, I've worked across fintech, healthcare, and SaaS, helping teams deliver reliable products, modernize existing platforms, and build applications that can grow with the business.I enjoy working across the entire product lifecycle—from discussing ideas and designing solutions to building, testing, and shipping features that people use every day. I like solving complex problems, improving system performance, and finding practical solutions that balance quality, scalability, and speed.What I enjoy most is collaborating with talented people. Whether I'm partnering with product managers, designers, or other engineers, I believe the best results come from open communication, thoughtful design, and a shared focus on building great products. I also enjoy mentoring teammates, sharing knowledge, and helping create an environment where everyone can do their best work.I'm always excited to work on meaningful products, take on new technical challenges, and keep growing as an engineer while contributing to a collaborative team. I'm open to US-based remote opportunities with multinational companies where I can build great products, work with talented people, and make a meaningful impact.Technical SkillsFrontend: React, Next.js , Angular, Vue.js, TypeScript, JavaScript (ES6+), HTML5, CSS3, Tailwind CSS, Redux, Responsive Web Design, Micro FrontendsBackend: Node.js, Java, Spring Boot, Python, C#/.NET Ruby on Rails , Go,, RESTful APIs, GraphQL, gRPCDatabases: PostgreSQL, MySQL, SQL Server, Oracle, MongoDB, DynamoDB, Redis, ElasticsearchCloud: AWS , GCP , AzureDevOps & Infrastructure: Docker, Kubernetes, Terraform, Jenkins, GitHub Actions, GitLab CI/CD, Azure DevOps, Helm, Infrastructure as Code (IaC), CI/CDSoftware Architecture: Microservices, Event-Driven Architecture, Domain-Driven Design (DDD), Design Patterns, SOLID Principles,TDDAI & Modern Technologies: Generative AI, Large Language Models (LLMs), AI Integration, RAG, AI AgentsDevelopment Practices: Agile, Scrum, SDLC, Git, Code Reviews, Pair Programming, Performance Optimization, API Design, Technical Documentation
