I’m a Full-Stack & AI Solutions Engineer with 10+ years of experience turning complex business requirements into reliable, maintainable software. I can take a project from requirements analysis and architecture through database/API design, development, deployment, and optimization. What I can help you with: • Java backend and microservices: Spring Boot, Spring Cloud, MyBatis, JPA • Python/FastAPI services, AI integrations, automation, chatbots, and data extraction • REST APIs, Socket/WebSocket, hardware SDKs, and communication protocols • MySQL, Oracle, TDengine, MongoDB, Redis, SQL tuning, backup, and recovery • Kafka, ActiveMQ, Kettle ETL, Docker, Jenkins, Nginx, Linux, and Git • Full-stack delivery with Vue and modern AI-assisted development workflows I have delivered environmental monitoring, GIS, smart transportation, parking, enterprise, and IoT systems. I am PMP certified and combine structured project management with hands-on engineering. I use AI to accelerate delivery while personally reviewing architecture, security, code quality, and reliability. Clear communication and dependable delivery are central to every engagement.

I love solving all kinds of complex tasks related to software design, architecture and performance. I possess a deep knowledge of how computer system works, from bare metal aspects to software architecture, distributed systems, large-scale databases and interaction between components. Knowledge and experience lets me both analyse any visible and invisible problems and find solutions for them, as well as design complex software systems. My passions are: design and administration of databases (SQL/NoSQL) of any scale, big data processing, data engineering, highload systems, software architecture & design, diagnostics and solution to performance problems, both hardware- and application design-related. I posses extensive skills and experience both in system administration of Linux & Unix systems (RHEL & derivatives, Debian, Solaris) and software development (backend, Python & C are primary languages I use for development). I have lots of practical experience about hardware tuning & optimizations, storage systems, virtualization and containers. Networks (organization, management, TC & filtering, routing, VPNs) and web technologies (servers, proxying & caching, load balancers, application servers integration, performance diagnostics). In the past I did system-level programming (using POSIX and Linux-specific APIs) and worked with IPC, multithreading, network programming, soft realtime. More recently, I switched to application programming (backend) and architecture designs: client/server, highload systems, microservices, messaging and streaming, cluster systems and failsafe designs. I also do performance monitoring, profiling, metrics & alerts integration (Prometheus, Sentry, etc). More than 10 years of experience working with databases allows me to do expert-level DBA tasks, as well as design and development of SQL databases. Optimizations, finding and fixing critical spots, maintenance & scaling, partitioning and sharding, failsafe designs (replication & standby, PITR) are things I have lots of knowledge and experience about. I also work a lot with NoSQL databases - key/value and Bigtable designs, creating architecture suitable for handling big data, data engineering, complex ETL pipelines. I've handled multiple complex SQL -> NoSQL migrations and SQL/NoSQL integration in various projects.

AWS-focused data engineer with 10+ years building and automating large-scale big-data systems. I design the pipelines that move and process data reliably — batch or streaming — and the cloud platforms they run on. My core stack is Hadoop, Spark, Hive, and data warehousing, paired with deep AWS expertise and four AWS certifications: Solutions Architect (Associate and Professional), Developer (Associate), and Big Data (Specialty). How I help clients: • Design and automate scheduled batch and streaming pipelines end to end, with Python for tooling and glue. • Lead cloud migrations and integrations — moving existing systems into AWS, or wiring them to it cleanly. • Ship containerized and streaming workloads on Docker and Kubernetes. Platform engineering is my specialty. I build internal developer platforms — a clean, self-service overlay on top of cloud and Kubernetes APIs — so your engineers ship faster without fighting the infrastructure underneath. Tell me what you're building, and I'll help you get it running reliably in the cloud.
