Sunil Nayak

Hi, my name is Sunil Nayak.

I completed my Master of Computer Applications from the National Institute of Technology, Raipur, in 2026.

After graduation, I joined HumanArchive, a robotics company focused on building multimodal training data to train robots for physically repetitive tasks. I worked there as a Technical Operations Intern, where I provided technical assistance to the operations team. My responsibilities included troubleshooting technical issues, resolving network-related problems, and helping ensure smooth day-to-day operations.

This experience helped me develop a structured approach to debugging and problem-solving.

After that, I joined FastFlowPe as a Backend Developer, where I've been working on building and maintaining backend systems for fintech products.

My work primarily involves designing and developing REST APIs, working with relational databases, designing database schemas, and building reliable backend services.

I've worked on several key features, including a payment links system, hosted checkout integrations, and backend improvements for the admin dashboard.

I've also worked on a Go-based report generation microservice using PostgreSQL and SQLC. One of the challenges was improving its ability to handle large datasets efficiently. I worked on optimizing the report generation and processing flow, enabling the service to handle up to one million records.

Alongside development, I've also been involved in debugging production issues, working with Dockerized services, integrating components through RabbitMQ, and investigating database and worker-related failures.

My primary backend experience has been with Python and Go, but the underlying concepts I've worked with, such as REST API design, relational database management, SQL, asynchronous processing, and service architecture, are transferable across backend technologies.

What I particularly enjoy about backend engineering is understanding how systems work internally, identifying problems, and building solutions that are reliable and maintainable.

I'm now looking forward to an opportunity where I can contribute my existing experience, work with a collaborative engineering team, and continue growing as a backend engineer.

Thank you for your time.

I am a SDE with hands-on experience in backend development, building scalable microservices, and developing automation solutions. Currently working at GoFastFlowPe, I specialize in Python, FastAPI, Golang, PostgreSQL, and SQL, with experience developing high-throughput report generation systems, payment integrations, and automated merchant onboarding workflows.

I have worked with technologies such as Django, Celery, RabbitMQ, Redis, Docker, and Supabase to build reliable and performance-oriented applications. My experience includes optimizing report processing capacity from 400K to 1M records, automating document verification workflows, and developing payment link systems with automated customer reminders.

Additionally, I have experience in technical operations, troubleshooting infrastructure issues, and improving system stability. I am passionate about problem-solving, backend engineering, system design, and building scalable solutions.
