Rahul Parida — Builder of SaaS things

— greeting from the editor —

hi, i’m rahul.
i build SaaS things,
then ask why don’t they exist already?

I’m a final-year Computer Science student at Siksha ‘O’ Anusandhan University, Bhubaneswar — perpetually convinced that the next problem I stumble into deserves its own product. My favourite kind of evening is one where I’ve gone from “huh, that’s annoying” to a working prototype by 2 AM, and my favourite kind of morning is the one where someone actually pays for it.

On this site you’ll find a curated, slightly opinionated tour of the products I’ve built, the internships where I learned how the grown-ups do it, and the things I’m tinkering with right now. It is intentionally a little handmade. sorry, not sorry.

About the editor

I’m a final-year CS undergrad at Siksha ‘O’ Anusandhan University, Bhubaneswar (CGPA 8.5), and I spend most of my waking hours somewhere between a terminal and a whiteboard. I love the moment a vague complaint turns into a working prototype — usually over a weekend, usually with too much coffee involved.

My current obsessions are agentic AI systems and the unglamorous backend plumbing that makes them reliable in production — think Kafka pipelines, Elasticsearch queries that don’t fall over at 3 AM, and circuit breakers that earn their keep. The projects further down this page are the receipts. — turn the page for the goods —

The workbench — products i’ve shipped

Six small product-shaped things I’ve built, mostly by turning a real annoyance into a weekend project. Some grew up into internship work, some are still sitting on my hard drive judging me.

PROJ #01 · 2026SHIPPED

LogSearch

Distributed Log & Ticket Intelligence

Production-grade analytics platform for high-volume logs and support tickets. Built around an event-driven microservice backbone with a soft spot for circuit breakers.

›Spring Boot microservices ingesting logs & tickets through Kafka topics
›Elasticsearch with fuzzy search, autocomplete, and Redis caching at the edge
›Resilience4j circuit breakers so one bad pod doesn't take the building down
›JUnit5 + Mockito + Testcontainers wired into CI/CD for every PR

PROJ #02 · 2026SHIPPED

KnowBot

Multi-Agent Enterprise Knowledge Assistant

A team of small AI agents (planner, retriever, reranker, generator, critic) that answer questions about messy enterprise wikis with grounded citations.

›Hybrid retrieval: vector search + BM25, with semantic caching for repeat questions
›Confidence-based guardrails so the bot politely declines rather than hallucinates
›Built an eval harness measuring faithfulness & relevance to debug answer quality
›Front-end in React with citations panel & diff view of what changed

PROJ #03 · 2025SHIPPED

Ticketer

AI-Driven Support Ticketing

Turns a flood of incoming tickets into a tidy queue: auto-categorised, prioritised, and routed to the right human.

›Role-based access: user, moderator, admin — gated by JWT
›Background jobs via Inngest for heavy LLM work that shouldn't block the UI
›LangChain-driven summaries & suggested replies for moderators
›Honest, useful AI features instead of AI-for-AI's-sake

Next.jsTypeScriptTailwindLangChainInngest

PROJ #04 · 2024SHIPPED

AnganSakhi

Field-Worker App for Anganwadi Centers

A mobile app that helps Anganwadi workers track children and mothers, with growth predictions built on UNICEF standards.

›Custom algorithm using UNICEF reference data for height/weight forecasting
›Scalable Express backend, deployed and in active use by real workers
›Offline-friendly flows because field internet is… optimistic

React NativeExpress.jsTypeScriptPostgreSQLTailwind

PROJ #05 · 2024SHIPPED

TalkATive

Real-Time Chat, with Presence

A full-stack chat app: instant messages, online indicators, throwaway rooms. Basically the project that taught me websockets aren't magic.

›Live presence tracking with online / offline indicators
›Dynamic rooms — create, invite, leave, rejoin
›Responsive UI that actually works on a phone in 2024

ReactExpressMongoDBSocket.IO

PROJ #06 · 2024SHIPPED

MealMate

Food Service, Web-First

A clean little food-ordering platform. MVC on the backend, GSAP for the flourish, Razorpay for the boring-but-important part.

›Full CRUD for menus, profiles, and orders — modular MVC structure
›Secure payments via Razorpay, including the ugly webhook parts
›GSAP animations sprinkled like seasoning, not poured like ketchup

Sign the guestbook

The internet used to have guestbooks. I’m bringing it back, kind of. If you read this far, drop me a line — a job lead, a critique of my CSS, a project idea, or just a hello. I read every message and try to reply within 48 hours, between sips of chai.
