Rearchitected the message delivery infrastructure for Memorea, a memory-focused AI assistant, replacing a cron-based system with an event-driven pipeline using AWS EventBridge and SQS, cutting delivery latency by ५०% and achieving near-१००% delivery reliability at scale.

Designed and built a multi-agent architecture from scratch to replace a single prompt-response model, implementing a custom agent harness with an orchestrator, specialised sub-agents, and tool-calling, enabling reliable multi-step task execution and reducing hallucinations.

Built email as a first-class channel for Memorea, including AI-powered auto-drafting and auto-labelling of incoming emails, and integrated WhatsApp Business API as a primary conversational channel for user interactions.

Built collaborative boards and lists within Memorea fully operable through natural language, allowing users to create, update, and manage tasks conversationally via the agent system.

Contributed broadly to product direction and backend architecture, working closely with the founding team on system design decisions as the product scaled.

Built and maintained backend microservices for identity and authorization modules using Node.js and NestJS, supporting enterprise SSO and multi-tenant access flows for a SaaS platform.

Designed and enforced fine-grained RBAC policies across distributed services, hardening platform security and reducing unauthorized access incidents.

Developed ETL pipelines to migrate large-scale enterprise data from Salesforce to AWS, handling schema transformation, data validation, and error recovery across millions of records.

Resolved critical PostgreSQL performance bottlenecks through targeted indexing and query optimization, reducing average query latency by ४०%.

Rearchitected the API Gateway for a high-traffic gaming platform, improving scalability and reducing latency by ३५%, enabling support for १००k+ concurrent users.

Designed real-time event pipelines using Kafka and Redis, achieving sub-१००ms game state updates and processing १०k+ events per second at peak load.

Built a WebSocket-based communication layer for live multiplayer interactions and real-time score updates, reducing client polling overhead by ६०%.

Developed ERC-20 and ERC-1155 smart contracts for in-game asset management and on-chain betting logic using Solidity.

Optimized PostgreSQL and MongoDB schemas through denormalization and compound indexing, improving write throughput by २५% and read latency by ३०%.

Architected the full backend from scratch for a Web3 banking platform, defining service boundaries, API contracts, and data models for a secure multi-chain financial product.

Built wallet management, transaction processing, and multi-chain asset handling modules, enabling users to interact with multiple blockchains through a unified REST API.

Implemented async transaction workflows using RabbitMQ, ensuring reliable, idempotent, and fully auditable processing of financial operations with zero data loss.

Established CI/CD pipelines with automated smart contract testing via GitHub Actions, reducing deployment time by ५०% and release risk.

Developed and audited Solidity smart contracts (ERC-20, ERC-721, ERC-1155) for NFT marketplace and DeFi applications, focusing on gas optimization and contract security.
