Vishal

Hi, I’m a backend developer with 7.5 years of experience, mainly working with Node.js and Java. My core experience is in building scalable backend systems, microservices, APIs, and working with databases, caching, and asynchronous/event-driven architectures.

Most of my production experience has been with Node.js, where I’ve built backend services focused on scalability, reliability, and performance. Alongside that, I’ve also worked with Java and have been strengthening my backend engineering depth there.

I enjoy solving system design and architecture challenges—whether it’s scaling services, improving performance, or designing clean backend systems. At this stage, I’m looking for roles where I can take more ownership in architecture and technical decision-making while continuing to build high-quality backend systems

Senior Developer at Synechron (2025-02 – 2025-09)

• Architected and owned the Auth Service for a banking application — JWT-based authentication with refresh token rotation and Redis-backed token blacklisting
• Containerised the auth service using Docker with multi-stage builds to keep production images lean and secure
• Designed Kafka event pipeline to publish login/logout audit events for compliance requirements, decoupling the auth service from downstream consumers
• Set up end-to-end CI/CD using GitHub Actions + AWS ECR + ECS Fargate with OIDC-based authentication (no long-lived AWS keys) — Docker images built in pipeline and pushed to ECR on every merge
• Deployed containers in private VPC subnets with ALB for SSL termination, secrets managed via AWS Secrets Manager
• Introduced manual approval gate for production deployments in GitHub Actions pipeline, reducing accidental prod releases.

• Built and optimised RESTful APIs in Node.js + TypeScript serving climate data to web and mobile clients, reducing average response time by 30% via query optimisation
• Designed NoSQL data models in MongoDB for time-series climate metrics, improving read performance for analytical queries
• Implemented CI/CD workflows on GitHub Actions with multi-stage Docker builds, cutting deployment time from manual ~45 mins to under 10 mins
• Enforced security best practices — input validation, rate limiting, helmet.js middleware across all API routes
• Led backend architecture decisions and conducted code reviews for a team of 5 developers

Software Developer at Xoxoday (2020-11 – 2021-12)

• Developed and maintained backend microservices using Node.js, ensuring high availability and scalability using Node.js and javascript.
• Collaborated with front-end teams to design and implement API endpoints.
• Improved database queries and data structures for optimal performance.
• Wrote comprehensive test cases using JavaScript and TypeScript to maintain code quality.
• Contributed to scaling the application to support over 100k Monthly Active Users (MAU).
• Optimized infrastructure and backend services to handle increased user load efficiently.
• Implemented caching strategies and load balancers to ensure system reliability.

Senior Engineer-IT at THOUGHTFOCUS (2022-01 – 2022-10)

• Developed and maintained RESTful API endpoints in Node.js, focusing on performance and reliability

• Led development of scalable backend applications and managed high-performance deployments on GCP
• Mentored junior developers through code reviews, enforcing coding standards and best practices across the team

Fullstack Developer at Charmboard (2019-04 – 2019-11)

• Designed and developed backend APIs for web and mobile applications using Node.js and JavaScript.
• Enhanced user experience by optimizing API performance and reliability.
• Worked with data scientists and analysts to integrate predictive features.
• Managed both relational and NoSQL databases.

Backend Developer at Nineleaps Technology Solutions Pvt. Ltd. (2016-03 – 2018-11)

• Designed and implemented software development of RESTful web services for various applications using Node.js (JavaScript and TypeScript).
• Optimized applications for speed and scalability using best practices.
• Collaborated with cross-functional teams to mitigate and resolve technical risks.
• Assisted in frontend development using templating engines and frameworks to ensure seamless integration.
• Participated in UI/UX discussions to create user-friendly interfaces for web applications.
• Built reusable components and libraries for future use in frontend projects.
• Conducted end-to-end testing of full-stack features, ensuring robust functionality and integration.
