Soumya Ranjan Swain / Full-Stack Systems Engineer / Bhubaneswar, Odisha, INDOSSIER 2026 · REV 01

I design and deploy zero-fail distributed systems.

AUDIENCE MODE:

I own backend architecture end to end: PostgreSQL schema and index strategy, Spring Boot service boundaries, transactional workflows, and the query paths that decide whether a batch finishes in minutes or hours. On a multi-state enforcement platform I cut end-to-end processing to roughly 30% of its previous runtime and stood up the disaster-recovery topology behind it.

PRIMARY: Java · Spring Boot · JPA/Hibernate
DATA: PostgreSQL · query & index optimization
RESILIENCE: DR architecture · multi-env deploys

THE BREAKDOWN / CONSTRAINT

Automated enforcement data arriving continuously from vehicle, toll and state government systems. Batch runtimes and unoptimized query paths throttled real-time monitoring, and a single-site deployment left no recovery posture for a platform operating across eleven states.

THE ARCHITECTURE

Rewrote hot query methods and server-side validation against PostgreSQL; restructured backend processing for high-volume ingestion; Spring Boot REST layer for detection, monitoring and enforcement workflows; Angular operator dashboards; disaster-recovery architecture with mirrored deployment workflow.

THE BREAKDOWN / CONSTRAINT

Healthcare delivery split across seven-plus actors — patients, doctors, nurses, caretakers, hospitals, laboratories, nursing homes — with no single model for appointments, diagnostics and consultations, and AI capability arriving as a separate research effort rather than a product surface.

THE ARCHITECTURE

Defined product structure, roles and technical approach, then owned the Spring Boot backend and PostgreSQL data model: REST APIs for appointments, diagnostic tests, consultations and services. Contributed React frontend, coordinated API contracts across teams, containerized components with Docker and wired CI/CD build and deploy.

EV Subsidy Portal

RESTRICTED · GOV SYSTEM

THE BREAKDOWN / CONSTRAINT

A citizen-facing subsidy service handling financial disbursement had to pass a formal application security audit while keeping submission, verification and status tracking responsive under public load. The audit surfaced multiple vulnerabilities across authentication, authorization and input handling.

THE ARCHITECTURE

Spring Boot REST APIs and workflow engine for submission, verification, approval and disbursement tracking; Angular self-service interface; remediated audited findings by hardening authentication, authorization, input validation and secure API handling; optimized PostgreSQL queries and operations.
