Full-stack software engineer shipping React and Node features for live SaaS.
IndiaWhat I'm looking for
I’m a full-stack software development engineer with 1 year of production experience building and shipping React.js + Node.js features for a live SaaS product. I’ve delivered 4 deployed MERN projects with GitHub Actions CI/CD, JWT authentication, and MongoDB at scale.
In my role at Inncircles Technologies, I engineered 10+ React.js UI components and Node.js/Express.js REST APIs across scheduling, approvals, RFI, and work-package modules—shipping changes to production with zero rollbacks across 4 releases. I’ve also reduced open defect count by 30% across 2 sprints by fixing React rendering issues and backend bugs through pair-programming.
I focus on measurable outcomes: I optimized backend performance using MongoDB aggregation pipelines to reduce average query execution time by 30%, defined Express.js API contracts with backend engineers to achieve zero integration defects for 3 consecutive sprints, and supported reliable delivery within a 6-person Agile Scrum squad on Jira.
