Work Experience

Software Developer

MatchBest Software Pvt Ltd

Dec 2024 - Present

Built a Java (Spring Boot) backend service for user and content management, exposing REST APIs for JWT-based authentication, user registration/login, profile management, and content CRUD, persisted to PostgreSQL through Spring Data JPA entities and repositories. Structured the service on a layered Controller → Service → Repository architecture with DTO request/response models, keeping business logic isolated in the service layer for reuse and testability, and enforcing DTO-level validation on required fields, formats, and invalid values before requests reach business logic. Implemented centralized exception handling via a global exception handler, replacing scattered per-controller try/catch blocks with a single consistent error-response contract for all frontend consumers of the API. Architected and shipped a Discovery feed and video-playback pipeline for a React Native (Expo) consumer app, cutting stream-start latency ~30% by designing a BytePlus VOD adapter layer with feature-flagged rollout and Zod-validated API contracts. Designed and deployed an Agentic AI outbound voice-bot integrated into the company's CRM, automating 200+ manual dials per day and lifting sales/support contact rates by an estimated 25%. Led end-to-end delivery of HealNova, a patient-facing healthcare app integrating Generative AI (BytePlus AI) for multi-modal (text + image) symptom triage, spanning the full flow from self-assessment to doctor booking. Designed and implemented an anonymous-to-authenticated session-migration system on a PostgreSQL-backed session store, preserving full user context across guest-to-signed-in upgrades while wiring GMA ad and analytics attribution across both session states.

Software Engineer

RV Tech

Jun 2024 - Dec 2024

Led front-end development of a TypeScript/React cancer-screening dashboard processing and visualizing 50,000+ blood-sample results, helping lab technicians flag anomalies 3x faster than the prior spreadsheet workflow. Owned the full product lifecycle of a new lab-workflow tool from discovery to launch — conducting field research across 10 users and 3 on-site sessions, authoring design docs, and shipping iterative releases with one engineer — driving a 40% gain in lab processing efficiency.
