About

Hello! I’m Rahul Singh Sengar, a results-driven Software Engineer with over 4 years of experience in building scalable, high-performance applications across web and mobile platforms. My core expertise lies in Go, TypeScript, React, Redux, MongoDB, and PostgreSQL, complemented by hands-on experience in GraphQL, gRPC, Cloud Infrastructure, and DevOps. I specialize in architecting and implementing microservices-based systems using Go and TypeScript, integrating them with rich, interactive frontends built with React and Redux. I leverage GraphQL for efficient data fetching and gRPC for high-performance service communication, ensuring seamless interoperability across distributed systems. With a deep understanding of both SQL and NoSQL databases, I design optimized data models that support complex, real-time use cases. My passion lies in building maintainable architectures, mentoring teams, and delivering robust, production-ready solutions that drive measurable business impact. Key Achievements: Architected and delivered end-to-end platforms using Go, TypeScript, React, Redux, GraphQL, gRPC, MongoDB, and PostgreSQL for web, Android, and iOS ecosystems. Enhanced application performance by 30% and reduced time-to-market by 25% through clean architecture, GraphQL APIs, and optimized CI/CD workflows. Cut infrastructure costs by 67% and boosted system performance by 92% via efficient resource utilization on AWS and GCP. Implemented microservices architecture with robust inter-service communication powered by gRPC and asynchronous event-driven pipelines. Ensured 99.99% uptime and seamless scalability across globally distributed deployments.

Senior Software Engineer

Sep 2023 – Present · 2 yrs 6 mos · Chandigarh, India · On-site

In my current role as a Senior Software Engineer, I design, develop, and optimize web and mobile applications built on a modern, scalable stack including Go, TypeScript, React, Redux, GraphQL, gRPC, MongoDB, and PostgreSQL. My primary focus is on delivering high-performance, secure, and user-centric applications that provide seamless experiences across platforms.
I work closely with cross-functional teams—including Product, Design, Backend, and QA—to architect, implement, and ship new features with a strong emphasis on clean architecture, scalability, and maintainability. I also drive performance tuning, code reviews, and CI/CD automation to ensure smooth delivery pipelines and production stability.
Beyond development, I actively contribute to infrastructure design, leveraging tools like Terraform, Docker, Jenkins, and Azure/AWS to manage deployments and implement Infrastructure as Code (IaC). I ensure all releases comply with platform and security standards while maintaining high service availability.
Key Achievements:
Engineered and optimized full-stack applications, improving overall system performance and user engagement metrics.
Implemented GraphQL and gRPC-based services, enabling faster, more efficient data and inter-service communication.
Reduced release cycle time by 30% through automated CI/CD pipelines and optimized build workflows.
Enhanced reliability and scalability of production systems using modern cloud infrastructure and monitoring practices.
Mentored junior developers in best practices for clean code, testing, and system design, improving overall team productivity.

Software Development Engineer II (SDE II)

Promoted

Jun 2022 – Aug 2023 · 1 yr 2 mos

As an SDE II at Dentsu, I engineered and customized app services with advanced cache
layer integrations, achieving a consistent Lighthouse performance score of 90+. I designed and
implemented a Microservices Architecture that increased system scalability by 40% and improved
fault isolation. My role involved building and deploying a custom notification engine for high-profile
clients, which contributed to a 20% increase in client satisfaction scores. I collaborated with cross-
functional design teams to convert wireframes into reusable UI components, facilitating alignment
between Design and Development Teams, which reduced development time by 30%. I also focused
on refactoring and optimizing UI components, leading to a 25% reduction in code redundancy.
Achievements:
Achieved a consistent Lighthouse performance score of 90+ through advanced cache layer
integrations.
Increased system scalability by 40% with the implementation of Microservices Architecture.
Contributed to a 20% increase in client satisfaction scores through the development of a custom
notification engine.
Reduced development time by 30% through effective collaboration with design teams.
