Aspiring SOC Analyst dedicated to developing a career in cybersecurity, with a focus on threat detection,
incident response, and log analysis. Experienced with SIEM tools and network traffic analysis. Previously
worked in IT as a backend developer, gaining practical experience with system architecture and high-load
systems.

EXPERIENCE
Sep 2022 - May 2025
Middle Backend Engineer

o I optimized the performance of a marketplace that was placing a heavy load on the database. I
implemented caching and configured indexes, which significantly reduced the number of database
queries and improved overall responsiveness.
o I optimized an inventory database containing millions of records by implementing partitioning. There
was also an issue where every minor action triggered a database query, so I refactored it to use
batch processing. This reduced inventory load time from 500 ms to 150 ms, even under load.
o I worked with RabbitMQ and a dedicated microservice to design and implement a scalable crafting
system. I built an event-driven architecture where crafting operations were processed asynchronously
through message queues, ensuring reliability and decoupling from the main application. This
approach improved system performance, handled high load efficiently, and allowed flexible extension
of crafting logic.

Aug 2025 - Nov 2025

Middle Backend Engineer

o Designed and developed an AI-driven chatbot assistant for international university admissions. The
system used OpenAI GPT models with vector embeddings to perform semantic search across a large
dataset of universities and admission requirements.
o Built and maintained a comprehensive vectorized knowledge base of global schools, programs,
tuition details, and application guidelines.
o Implemented conversational recommendation logic that matched users with suitable academic
options based on their goals and background.
o Integrated payment systems using RevenueCat and Stripe for subscription management

PROJECT
o Built a home SOC lab using Splunk / IBM QRadar with log ingestion and monitoring setup
o Created SIEM correlation rules for basic threat detection
o Simulated network attacks and analyzed them using Wireshark and Nmap
o Implemented basic mitigation techniques and analyzed detection effectiveness
o Completed hands-on cybersecurity labs on Hack The Box and TryHackMe
