## About

Software Engineer specialising in scalable systems and architecture\. I design and build robust systems that scale\-from API design and database modelling to performance optimisation, authentication flows, caching strategies, and event\-driven architectures\. My work centres on MVC patterns, 0→1 product launches, and architecting systems built to perform under load\. I’m passionate about writing clean, maintainable code and services that other engineers enjoy working with\. I share insights on backend systems, architecture decisions, and engineering workflows on LinkedIn and X\.

## Work experience

Software Engineer at GetSwags, Apr 2026 \- Present · 5 mo, Bangalore

Uniswap Hook Incubator — Cohort 5 \(UHI5\) at Atrium Academy, May 2025 \- Jun 2025 · 1 mo, Web3, • Selected for Uniswap Hook Incubator Cohort 5, a technical program focused on Uniswap v4 architecture, hooks, and AMM design\. • Built a blockchain\-based lottery game using Uniswap v4 Hooks, working with 8 of the 14 available pre\- and post\-execution hook points to customise protocol behaviour\. • Designed and implemented Solidity\-based hook logic affecting protocol execution, including interactions with swaps, fees, liquidity, and access\-control flows\. • Used Foundry for development and testing, including automated test suites and fuzz testing to validate protocol behaviour across different execution scenarios\. • Deployed the hook\-based application to a testnet and demonstrated the complete implementation as the cohort’s final project\. • Worked directly with Uniswap v4 pool state, liquidity logic, transaction execution, and hook lifecycle to understand how protocol\-level extensions can modify AMM behaviour\.

Founder & Software Engineer at OnChainBag, Mar 2025 \- Dec 2025 · 9 mo, Bangalore, • Built and deployed Bag \(OCB\), a production blockchain application on Flow Mainnet, taking the product from protocol design through application development and deployment\. The protocol was designed as a yield\-bearing GameFi NFT system powered by Flow VRF\. • Took the product from 0→1, owning the technical architecture and implementation across smart contracts, application workflows, transaction processing, and the React frontend\. • Designed application workflows around blockchain transactions and asynchronous state changes, covering NFT minting, transaction tracking, reward calculation, and reward distribution\. • Built transaction\-processing logic to track on\-chain activity and synchronise application state with blockchain operations\. • Implemented automated reward workflows, processing 24 reward\-related transactions and distributing 18 Flow tokens across the production system\. • Deployed and operated the application in production, supporting 15 NFT mints across 10 users\. • Owned the engineering lifecycle from protocol design and implementation through deployment, monitoring, and production maintenance\.

Freelancer Software Engineer at Freelance, Nov 2024 \- Feb 2025 · 3 mo, Bangalore, Worked independently with clients to design and build production smart contract systems across DeFi, NFT infrastructure, DAO tooling, and token\-gated applications\. Delivered 10\+ production\-ready contracts including: \- Factory/proxy architectures \- Membership systems \- Campaign and referral protocols \- NFT infrastructure \- DAO tooling Also focused heavily on contract optimisation and backend integration: \- Reduced gas costs and bytecode size by 20–35% using Yul, Huff, and opcode\-level profiling \- Built backend interaction layers and event\-processing workflows \- Designed scalable on\-chain systems with upgradeability and modularity in mind This phase helped deepen my understanding of protocol design, low\-level EVM behaviour, and production smart contract architecture\.

Software Engineer at Flow, Mar 2023 \- Oct 2024 · 1 y 7 mo, Bangalore, • Worked on CryptoKnight, a production learning platform for developers, contributing across backend architecture, APIs, application workflows, and developer education\. • Designed and built 50\+ REST API endpoints using Node\.js and Express for user management, lessons, assignments, progress tracking, and application workflows\. • Designed MongoDB data models and application logic for managing users, learning content, assignments, and progress across the platform\. • Implemented authentication and authorisation flows to secure user and application\-level access\. • Added Redis caching for frequently accessed data to improve backend performance and reduce repeated database operations\. • Built asynchronous email processing using BullMQ, moving mail delivery into background jobs instead of handling it within API request flows\. • Deployed the platform to production and supported 800\+ developers using CryptoKnight to learn blockchain concepts from beginner to advanced levels\. • Conducted and participated in developer workshops and hackathons across India, helping developers learn and build with blockchain technologies\.

Software Engineer at MikoSea, Jul 2022 \- Feb 2023 · 7 mo, Bangalore, • Worked on backend services and real\-time infrastructure for a production NFT marketplace supporting listings, purchases, auctions, payments, and transaction processing\. • Designed and built Node\.js REST APIs supporting marketplace operations, including NFT listings, purchases, auctions, user workflows, and transaction tracking\. • Built backend systems supporting 10K\+ users, 20K\+ NFTs minted and listed, and 200K\+ transactions across the platform\. • Designed data models and backend workflows using PostgreSQL and MongoDB, handling application, marketplace, and transaction data\. • Implemented Redis caching for frequently accessed data using cache\-aside patterns and TTL\-based invalidation to reduce repeated database operations\. • Built asynchronous background processing with BullMQ, moving long\-running and non\-blocking operations out of synchronous API request flows\. • Supported an NFT sale with 8K\+ users, contributing to the backend infrastructure required to handle a high\-concurrency production event\. • Wrote automated tests and used application monitoring to identify and investigate performance and reliability issues in production\.
