A Feature Presentation

Not a portfolio. A directed experience, presented in reels. Best viewed in a dark room, with sound.

AN ORIGINAL SCREENING

Software Engineer · Mumbai · Chennai, India

Backend systems, cloud infrastructure, and the unglamorous engineering that makes numbers go down and reliability go up.

The Craft

Chapter Two · an opening-credits sequence

WRITTEN, DIRECTED & DEPLOYED BY THE SUBJECT

A cast of tools, billed in order of appearance. Nothing here for show — only what earns its place on set.

Hover to slice each card clean through

APIs that stay boring under load. Contracts before code, guards at every door.

Ship on green, roll back in seconds. The pipeline is the product too.

The right store for the query. Columnar when it counts, indexed where it hurts.

Fundamentals over frameworks. Know the machine, then pick the language.

Models that earn their latency. Proofs where correctness is not negotiable.

SCENE 3A · INT. CLOUD — CONTINUOUS

Entrupy

MLOps Intern/May 2026 — Aug 2026/Remote · Multi-cloud

  • 01Built an internal multi-vendor cloud cost dashboard (FastAPI, DuckDB, PyArrow/Parquet, AWS, Docker) exposing spend via REST, a Slack bot, and an MCP server across AWS, Verda, Pinecone and others — shipped through GitHub Actions CI/CD to EC2.
  • 02Designed a DynamoDB-backed RBAC system with team groups, Super Admin / Owner / Member permissions and audit logging; extended the Slack bot & MCP Q&A to enforce resource-level access control.
  • 03Implemented per-user Verda cost attribution, daily Slack reports and automated spike detection — uncovering untracked resources.
  • 04Leading an internal dataset service on AWS event-driven infra with Parquet storage and SDK/CLI tooling for sub-5-minute dataset creation.

SCENE 3B · INT. LAB — FLASHBACK

DRDO — Scientific Analysis Group

Research Intern/Jun 2025 — Jul 2025/On-site · Formal Methods

  • 01Researched formal verification techniques — SAT/SMT solving and model checking — and verified 10 logic-based system models using Z3 and Alloy, uncovering edge-case failures.
  • 02Applied LTL/CTL temporal logic and loop invariants to validate correctness in concurrent software protocols.

The Feature

Chapter Four · three scenes · each its own world

Feature 01 of 03

HireHelp

AI-Assisted Recruitment · Full-Stack

A recruitment platform where every hiring decision leaves a tamper-proof trail — and the right candidate rises without waiting.

  • React
  • FastAPI
  • MongoDB
  • Solidity
  • Groq LLM
  • FAISS

Selected scenes

01

Full-stack platform with JWT-based RBAC (Applicant / Recruiter / Admin) enforced via API guards and role-aware routing.

02

RAG-based resume-matching pipeline (sentence-transformers, FAISS) with cached chunking and async processing for low-latency, non-blocking scoring at scale.

03

Blockchain-backed audit logging (Solidity, web3.py, Ethereum Sepolia) for verifiable, tamper-proof hiring records.

Feature 02 of 03

Rural-Digital-Bank

ML + Blockchain Fraud Prevention

A fraud-prevention system that scores risk in under a millisecond and writes the verdict somewhere no one can quietly rewrite.

  • React
  • Flask
  • scikit-learn
  • Solidity
  • Ethereum

Selected scenes

01

Hybrid fraud-detection pipeline pairing an Isolation Forest anomaly model with rule-based risk multipliers — real-time 0–100 risk scores at sub-millisecond inference.

02

Client-side browser fingerprinting and transaction telemetry for real-time fraud signals with no backend round-trips.

03

Gas-efficient Solidity contracts (storage packing, paginated queries) logging tamper-proof audit trails on Ethereum.

Feature 03 of 03

TourSphere

Full-Stack Tour Booking Platform

A booking platform built on discipline — reusable controllers, geospatial search, and an API hardened for the real world.

  • Node.js
  • Express
  • MongoDB
  • PhonePe

Selected scenes

01

REST API with an MVC, DRY controller-factory pattern and reusable CRUD logic — cutting controller duplication by 80%.

02

Geospatial search (MongoDB 2dsphere) with dynamic filtering, sorting and pagination for tour discovery.

03

JWT auth (−90% access bugs in testing), PhonePe payments, an in-memory image pipeline (multer + sharp), and hardening via helmet, rate-limiting and sanitization.

Special Thanks

  • Every stack trace that eventually made sense
  • The reviewers who said "make it simpler"
  • Coffee, and the occasional 3 AM incident

No legacy code was harmed during production.

If the story landed, the next scene is a conversation.

Abandoned Concept

The intermission

A literal mid-scroll intermission card with a countdown. Charming for exactly one viewing. Cut.

Rejected UI

Skeuomorphic film strip nav

A sprocket-holed film strip you dragged to scrub reels. Gorgeous, unusable on mobile. Retired to the archive.

Failed Experiment

Real 3D projector booth

A WebGL booth casting the beam in true volumetric light. Beautiful at 20fps. The illusion beat the simulation.
