Microservices & Distributed Systems
Expertise in designing and building microservices architectures and distributed systems, including scalable backend services handling up to 120K RPM with microsecond-level response times.
Backend Development with Golang, C++ and Node.js
Proficiency in backend development using Golang, C++, and JavaScript (Node.js), with hands-on experience building REST APIs, workflow automation engines, and high-throughput data processing systems.
AI-Powered Platform Engineering
Design and development of AI-powered platforms, including LLM-based agents for automated customer-support bot generation and quality-control systems evaluating 10k interactions per day.
Database Management
Experience with multiple database technologies including MongoDB, Redis, MySQL, DynamoDB, and OpenSearch for scalable and high-performance data storage and retrieval.
Messaging & Streaming
Practical knowledge of messaging and streaming systems such as Kafka and AWS SQS for building event-driven and asynchronous backend architectures.
Monitoring & Observability
Utilization of Prometheus and Grafana for system monitoring, observability, and performance tracking in production environments.
Multi-Channel Integration
Building and scaling multi-channel integrations for platforms such as WhatsApp and Facebook Messenger using APIs, processing up to 25k messages per day for seamless omnichannel customer support.
Load Testing & Performance Optimization
Conducting large-scale load testing across multiple microservices, simulating 5x normal traffic to identify bottlenecks, and optimizing batch processing to reduce data export times from 2 hours to under 10 minutes.
Workflow Automation
Engineering event-based and time-triggered automation flows for ticket management, including automatic responses, assignments, and escalations, reducing manual effort by 30% and improving SLA adherence.

Project history
Led the design and development of an AI-powered quality-control platform for evaluating support interactions across voice and chat, enabling automated quality assessment for 10k interactions per day. Designed a configurable dynamic-field framework for custom evaluation parameters and developed a graph-based execution framework for real-time voice and chatbot action execution.
Led backend development of an LLM-powered agent converting natural-language business requirements into fully configured customer-support bots. Implemented a VM2-based JavaScript execution engine with under 100ms latency. Built and scaled multi-channel integrations for WhatsApp and Facebook Messenger processing 25k messages per day. Led a team of 15 members and owned end-to-end on-call operations, reducing MTTR by 40%.
Designed and developed a no-code conversational bot builder enabling business teams to create bots through an intuitive UI. Developed an email-to-ticket system supporting 30-40k emails per day. Implemented predefined canned responses reducing first response time by 50%. Optimized large-scale data exports reducing processing time from 2 hours to under 10 minutes.
