Aasheesh Rathour
I am Aasheesh, a Software Engineer who loves building things in Golang. My goal is to achieve the mythic number $1 million. I learn things very fast. I built Muze (MVP in 1 month) by learning and implementing Kafka, Next.js, Redis, and AWS. Previously built Capsule.email (Domain backed by Peerlist founder). I only like to code and don't have any hobbies—I spend most of my time in code.
Experience
journey- Architected and delivered entire platform MVP in 30 days using microservices architecture with Kafka, Redis, and Pub/Sub, handling 10,000+ concurrent WebSocket connections.
- Built production-grade real-time chat system with message delivery workflows, read receipts, and push notifications.
- Integrated Mollie and Crypto.com payment gateways with webhook handling and subscription flows processing.
- Engineered advanced search using Elasticsearch, vector embeddings, and Ollama (LLM inference) for semantic search and personalized recommendations.
- Leading full-stack development with Go backend microservices and Next.js frontend, focusing on real-time notifications and scalable infrastructure.
Selected Works
High-performance Go SDK for the Lamatic AI platform. Built with idiomatic internal/pkg separation, supporting complex AI orchestration through workflow (Flows) execution, Agent interaction, and robust job polling with dual-layer (API Key & JWT) authentication.
LLMs suck at date math. Built this to solve it. A LangGraph agent that handles complex scheduling by separating intent extraction from deterministic resolution. It features robust day-of-week logic, cross-timezone conversion (IST/UTC/Local), participant extraction, and anchor-based ranking to find the perfect slot. Zero hallucinations, 100% accuracy.
Indestructible memory for AI Agents. A high-performance, durable runtime built in Go. Read the story →
Solving the AI Cold Start problem. Achieving 0.003ms wakeup times for massive models. Read the whitepaper →
AI-powered email template platform. Domain backed by Peerlist founder.
Notch clipboard manager for Linux and Windows. Received 55+ upvotes.
Experiments
A physics simulation in Go where water drops interact with and displace sand particles.
Built a lock-free, multi-producer/multi-consumer ring buffer in Go. Zero memory allocations, 4x+ faster than Go channels, and performance scales with batch size.
Emoji Feedback
Interactive emoji feedback components with smooth animations and haptic feel.
Full-Text Search Engine
Built a fast, local full-text search engine in Go from scratch. Features 100 concurrent workers for indexing, inverted index building, and fuzzy search (Levenshtein distance) for typo tolerance. Like a tiny, lightweight Elasticsearch.
