• Designed the DB: drew ER-diagram, decomposed it to 3NF, added indexes & triggers, introduced some PL/pgSQL procedures for effective data-layer computations
• Researched the distributed data system: 2PC, Saga (choreography & orchestration), polyglot persistence, CAP theorem, eventual consistency, sharding, replication, consensus algorithms (Paxos, Raft), event sourcing, CQRS
• Discovered the internals of PostgreSQL: WAL, pgpool, failover configuring, shared buffers, MVCC, VACUUM, TOAST-tables, replication (streaming, logical)

• Built and automated infrastructure with AWS, Terraform, Ansible, and Cloudflare
• Deployed apps using Docker, Docker Compose, Docker Swarm, Vagrant, and Kubernetes
• Set up observability with Prometheus, Grafana, and ELK Stack (Elasticsearch, Kibana, Logstash)
• Applied architectural patterns: bastion host, load balancing, circuit breaker, message broker (Kafka)

• Built two bare‑metal x86 ASM apps: a string manipulator and a dictionary data structure
• Implemented C programs: BMP rotation and sepia filter using SIMD/vector instructions
• Wrote C++ benchmarks for CPU‑ and IO‑bound algorithms; profiled with Windows Performance Analyzer on Windows and perf, top, iostat, vmstat, bpftrace on Linux
• Implemented C++ disk page caching
• Used build tools: CMake, Make, Visual Studio
• Researched Windows and Linux kernel internals, structure of file systems (FAT, ext4)

• Learned core Java: OOP principles, java.io/java.nio, networking, JDK layout, GC internals
• Studied algorithms & data structures: linked lists, stacks, queues, hash tables, heaps, trees (BST, red–black, segment), tries; sorting (quick/merge/heap); searching (binary, ternary); graphs (BFS/DFS, Dijkstra, Bellman–Ford, Floyd–Warshall); DP, greedy, divide & conquer, union–find
• Learned design patterns: creational (Singleton, Factory Method, Builder, Prototype); structural (Adapter, Bridge, Composite, Decorator, Facade, Proxy, Flyweight); behavioral (Strategy, Observer, Command, State, Template Method, Iterator, Mediator, Memento, Chain of Responsibility, Visitor); concurrency (Thread Pool, Future/Promise, Producer–Consumer, Read–Write Lock); architectural (MVC/MVP/MVVM, Clean Architecture, DDD)
• Built a Java server: multithreaded request handling, bare TCP sockets, shared JAR library for DTOs
