Reduced manual effort by 75%, architected a distributed real-time ERP workflow automation platform with event-driven architecture; designed scalable WebSocket/REST APIs with FastAPI, Apache Kafka & Redis; Langfuse for observability, and then wrote the whole thing in GO utilizing channels and Goroutines achieving 5x latency improvement. Designed & implemented scalable, high-performance Search Engine with ElasticSearch and LLM, enabling natural language retrieval across 100k records. Delivered robust API design (FastAPI) and a top-k most frequent results, all with sub-second response times & easy extensibility. Developed a central RAG system using FastAPI, MySQL, Qdrant, and Nomic embeddings, implementing Strategy/Factory patterns for modular architecture, with Docker containerization and Kubernetes deployment, enabling scalable semantic search and easy addition of new models/parsers. Architected a robust, policy-driven prompt guardrailing framework for multi-agent systems, combining regex, heuristic, and LLM-based detectors with per-agent configurations to vet inputs/outputs and enforce enterprise-grade safety and compliance. Implemented long-term agent memory using Mem0, Memori, and custom session-level base prompts/chat threading, delivering safer, more context-rich interactions, reducing hallucinations, and materially improving answer quality over time.

Architected central LLM interaction service supporting multiple language models with intelligent load balancing, ensuring 99.9% service availability. Pioneered specialized prompt repository enabling dynamic prompt selection across services, improving code maintenance efficiency by 4x. Engineered shorts-creation and video-summarizing module, accelerating production time by 5x while achieving industry-leading 60% publishable rate. Co-developed text-to-video engine generating multilingual videos at scale from raw text, serving 100k+ unique users and enterprise clients. Built proshorts web & mobile application from ground up, supporting 10k+ DAU with Firebase-powered authentication. Orchestrated end-to-end Payment Module using Stripe, managing complex subscription lifecycles and transaction flows involving 10k+ users & 100s of transactions per week. Unified Payment Module across diverse platforms (proshort+, L&D platform, video consumption platform) through centralized user identity management. Delivered data-intensive CRM integration module synchronizing deals, contacts, companies, and emails via event-driven architecture using queues, Pub-Sub patterns, strategic caching, and automated schedulers.
