THUSHAR
I build full-stack products, real-time systems, and practical software with a focus on reliability, clear system design, and real-world utility.
ACADEMIC BACKGROUND
B.E. Computer Science (2024–2028)
Sri Sivasubramaniya Nadar College of Engineering
Chennai, Tamil Nadu, India
Building practical software with curiosity, discipline, and purpose.
I am a Computer Science Engineering student at Sri Sivasubramaniya Nadar College of Engineering, Chennai. Rather than only studying computer science concepts on paper, I spend most of my time writing code, architecting full-stack applications, and turning ideas into software that works reliably.
My work spans both frontend interfaces and backend infrastructure. I enjoy designing clean user experiences, structuring resilient database schemas, and tackling real engineering trade-offs. What excites me most is taking a real-world bottleneck—like high-concurrency waitlists, freelance escrow safety, or real-time communication—and engineering a clean, dependable solution.
Outside of coursework, I work on commercial freelance engagements, compete in hackathons and Capture The Flag (CTF) security contests, and contribute to campus technical communities including the SSN Coding Club, AI Student Chapter, and SSN Gaming Club.

How I design and engineer systems.
I prioritize operational reliability, transaction boundaries, and defensible architecture over superficial visual shortcuts. These core paradigms guide my work:
FULL-STACK PRODUCTS
Building reliable web applications across the entire stack—from high-performance frontend interfaces to transactional backend APIs and cloud databases.
- →Next.js App Router, TypeScript, React Server Components
- →RESTful API design and third-party gateway integrations
- →Relational schemas, ORM data pipelines, and clean abstractions
REAL-TIME SYSTEMS
Engineering low-latency bidirectional communications, live telemetry streams, and event-driven architectures that maintain synchronization across clients.
- →WebSocket streaming, Pub/Sub channels, and live canvas rendering
- →Dual-fallback mechanisms (WebSockets paired with heartbeat polling)
- →Distributed cache synchronization with Redis and broadcast state
SECURE SYSTEMS
Protecting business data and transactional workflows through strict authorization boundaries, cryptographic verification, and tamper-resistant audit trails.
- →Application-level escrow mechanisms and explicit state machines
- →Row-Level Security (RLS) and granular Role-Based Access Control (RBAC)
- →Audit logging, webhook signature verification, and attack surface reduction
SYSTEM DESIGN
Designing resilient system architectures capable of handling concurrent access, preventing race conditions, and preserving strict data isolation.
- →Multi-tenant isolation architectures with dedicated schema boundaries
- →Atomic SQL row locking (SELECT ... FOR UPDATE) under concurrent load
- →Fail-safe session recovery and defensive backend state machines
Commercial and freelance engineering.
Delivering robust full-stack solutions, concurrency-safe database RPC functions, and real-time streaming telemetry for client products.
- ▪Reduced inventory reconciliation from hours to minutes across four shop branches by implementing transactional PostgreSQL RPC functions with row-level locking.
- ▪Closed a recurring cash-skimming loophole by adding role-based authorization and audit logging.
- ▪Built an installable, offline-first Progressive Web App with real-time dashboards for tracking inventory, sales, and profit.
- ▪Integrated an existing HTML Canvas component into the Next.js dashboard for Drona, an educational platform where instructors and students interact in a classroom-like interface while patient monitoring data streams in over WebSockets.
- ▪Hooked up the dashboard to the existing WebSocket stream so live monitoring data rendered on the canvas in real time.
- ▪Ran alpha testing on the dashboard and logged bugs for the team to fix.
