About

Professional summary

I am a Senior Full-Stack Engineer with over six years of experience delivering production SaaS, fintech, enterprise, marketplace, and e-commerce platforms for international clients.

I build end-to-end applications using React, Next.js, Node.js, NestJS, Python, Django, FastAPI, and Java Spring Boot. My work spans frontend development, backend services, API design, database architecture, cloud deployment, and performance optimization.

I currently architect AI-driven voice-calling systems that combine OpenAI and Gemini large language models with real-time text-to-speech services. I focus on building reliable conversational agents capable of lead generation, customer qualification, and sales workflows at scale.

I have strong experience designing asynchronous processing pipelines, microservices, event-driven systems, queues, caching strategies, and scalable data platforms. I regularly work with MongoDB, PostgreSQL, Redis, RabbitMQ, BullMQ, Kafka, Docker, AWS, and CI/CD automation.

I enjoy owning products from technical discovery through deployment and continuously improving reliability, system performance, and delivery speed. I have contributed measurable gains in API latency, transaction throughput, workflow automation, and user engagement while collaborating with distributed agile teams.
