EXPERIENCE

Senior Backend Engineer

ARBISOFT. 05/2024 – Present

• Engineer scalable backend infrastructure for high-traffic AI SaaS platforms, effectively processing heavy production-level data loads.

• Architect LLM orchestration workflows and RAG pipelines using LangChain and OpenAI to drive intelligent text and voice features.

• Optimize core API performance, slashing response times to maintain consistent low-latency standards across critical user flows.

• Manage containerised cloud deployments with Docker, Kubernetes, and automated GitHub Actions CI/CD workflows.

• Collaborate closely with product and engineering teams to trans- late complex business metrics into high-performance database schemas.

Senior Software Engineer

SHOPDEV. 03/2022 – 04/2024

• Built and optimized high-throughput RESTful APIs using Django and FastAPI to handle complex records and heavy data manipulation.

• Structured complex database layers on PostgreSQL and Redis, im- plementing background workers via Celery to isolate heavy compu- tations.

• Scaled infrastructure architectures to support severe concurrent user loads while preserving system stability and reliability.

• Refactored legacy systems to resolve performance bottlenecks and established automated unit testing with Pytest.

• Integrated multi-tenant access models and secure authorization rules to ensure rigid data isolation across enterprise client workflows. Software Engineer

TECHFINITY. 06/2020 – 02/2022

• Developed robust data processing and automation web scraping pipelines using Scrapy and Playwright for large-scale data sets.

• Maintained and enhanced secure communication lines using Web- Sockets for real-time dashboard data synchronization.

• Deployed scalable cloud components across AWS services, includ- ing EC2, Lambda, and S3 storage mechanisms.

• Implemented rigid authentication and access controls leveraging JWT and OAuth2 standards to safeguard sensitive routes.

• Optimized asynchronous task processing setups to safely manage incoming data streams without causing worker starvation. PROJECTS
