Data consultant with major cloud service provider badges: Certified Google Professional Data Engineer Certified Microsoft Azure Data Engineer Certified AWS Solutions Architect Certified AWS Developer Certified Snowflake SnowPro Core Currently, I'm working as a Senior Data Engineer in a North-European identity verification company, where I do data integrations into cloud data services, design and implement data architecture and data transformation solutions, perform data lake and data warehouse analysis and development, and create ELT pipelines. Before moving to my current job, I was working in a Nordic consultancy company as a data engineer, and earlier I worked as a data warehouse architect in a multinational financial organization Swedbank where I designed and modeled the data architecture for the data warehouse team, developing the data integration pipelines, loading data from various data sources, controlling data quality management, etc. During my career, I have been dealing with a variety of software and database systems in the cloud and on-premise, gained excellence in programming languages and tools like Python, R, SQL, Java, Apache Spark, Apache Airflow, dbt, Google Cloud Platform, Microsoft Azure, Amazon Web Services, Snowflake, Javascript. In 2020 I obtained a master's diploma in Innovation and Technology Management at the University of Tartu, Estonia.

I’m a web developer from Estonia with a higher engineering degree and experience in PHP, JavaScript, React, Node.js, HTML5, CSS, MySQL, MariaDB, Python, WordPress, Ubuntu, and Debian. I’ve been working in web development since 1999, helping small businesses and entrepreneurs build fast, secure, and modern websites using WordPress, HTML, CSS, and PHP. Whether you need a landing page, business site, or a custom feature — I deliver clean code and clear communication. To build my reputation here, I’m offering my services for a low rate. I’m reliable, detail-oriented, and always finish what I start. In addition to web development, I can also help you configure your server, install or update software, and keep your system secure. Using outdated software on your server is like driving a car without brakes — it’s only a matter of time before something goes wrong. Let’s prevent that! If you need help with website development, bug fixes, or server maintenance — feel free to message me! I'm here to grow and help you at the same time.

All you need is 1 engineer who understands both AI and the data behind it to build reliable AI systems with clean data pipelines, secure integrations, and failure handling built in... I build production AI/ML and agentic applications. From LLM-powered automation to real-time speech-to-speech AI platforms backed by a strong data engineering foundation that most AI developers lack I help SaaS, AI Fintech and enterprise teams design reliable systems across the full path: data ingestion to warehouse to orchestration to ML-ready datasets to LLM/RAG workflows to automation and decision systems 𝗛𝗘𝗥𝗘'𝗦 𝗛𝗢𝗪 𝗜 𝗖𝗔𝗡 𝗛𝗘𝗟𝗣 𝗬𝗢𝗨... - Agentic AI & LLM Systems: I build LLM-powered applications and agentic workflows that automate business processes, connect to internal tools and work with real operational data. This includes RAG/GraphRAG systems, embeddings, vector search, prompt workflows, retrieval evaluation, FastAPI-based AI services, and reliable orchestration around LLM pipelines - RAG, GraphRAG & AI Knowledge Systems: I can help you build retrieval systems that are grounded in your documents, databases and business rules. My data engineering background helps me design better ingestion, chunking, metadata, data quality and retrieval pipelines so the AI layer has clean and trusted information to work with - AI Ready Data Engineering: Your AI system is only as good as the data behind it. I design and optimize production pipelines using Python, SQL, Snowflake, dbt, Apache Airflow, BigQuery, AWS, and modern ELT patterns. I focus on reliability, monitoring, data quality, incremental processing, and clean data models that can support analytics, ML, and AI applications - ML Pipelines & Automated Decision Systems: I have experience building analytics and ML-enabled systems such as anomaly detection, behavioral scoring, feature pipelines, fraud/risk insights and operational monitoring. I focus on practical ML and automation that business teams can trust, understand, and use in production - Data Platform Modernization: If your dashboards are slow, pipelines fail silently, KPIs do not match, or your team spends too much time reconciling data manually, I can help modernize the architecture. I have worked on cloud data platforms, warehouse design, dbt modeling, Airflow orchestration, and KPI frameworks that make reporting and AI use cases more reliable 𝗥𝗘𝗦𝗨𝗟𝗧𝗦 𝗜 𝗛𝗔𝗩𝗘 𝗗𝗘𝗟𝗜𝗩𝗘𝗥𝗘𝗗 - Reduced ETL runtime from 35 minutes to 7 minutes through pipeline and query optimization - Improved reporting latency from 24 hours to under 15 minutes with modern warehouse and ELT design - Improved pipeline reliability to 99.8% with orchestration, monitoring, retries, and validation - Increased BI adoption from 20 to 80+ users by standardizing metrics and improving reporting access - Supported analytics and ML use cases across fintech, SaaS, procurement, media, and enterprise environments - Built data foundations for AI-ready analytics, anomaly detection, and LLM-powered retrieval workflows 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞? I build proper custom AI and automation systems the same way I build production data platforms: reliable, documented, testable and designed for real users. I care about architecture, maintainability, monitoring, data quality, and business outcomes 𝗧𝗘𝗖𝗛 𝗦𝗧𝗔𝗖𝗞: AI/LLM: RAG, GraphRAG, LLM Integration, Embeddings, Vector Search, Prompt Workflows, Retrieval Evaluation Backend/API: Python, FastAPI, REST APIs, Async Workflows, Automation Services Data Engineering: Snowflake, Dbt, Apache Airflow, BigQuery, SQL, Python, ETL/ELT, Data Modeling Cloud/Infra: AWS, Docker, CI/CD, Monitoring, Production Deployment Patterns Analytics/ML: Anomaly Detection, Feature Engineering, ML-ready Datasets, BI, KPI Frameworks P.S. If you need someone who understands both; data layer and the intelligent AI layer on top of it, I would be happy to discuss your workflow and recommend the most practical production-ready approach

I’m a Senior Backend Engineer and Software Architect with 9+ years of experience building systems that don’t just work but scale, evolve, and stay maintainable over time. I focus on designing and delivering high-performance, reliable backend systems from early-stage concepts to production systems handling real-world complexity. My work spans microservices architecture, event-driven systems, real-time applications, and modern data platforms (including vector databases). I help teams move from "it works" to systems that are clear, stable, and ready to grow. Over the years, I’ve built and maintained platforms across: - Messaging - Audio & Video Streaming - Ride-sharing - eCommerce - FinTech - EdTech - IoT - Blockchain - Enterprise SaaS often operating at scale, with complex workflows and millions of users. What I bring • Strong backend architecture, systems that are easy to reason about and extend • Deep experience in microservices and event-driven design (Kafka, Temporal, Debezium) • Real-time systems expertise, messaging, streaming, live data pipelines • End-to-end ownership, from system design to production deployment • A focus on clarity, not just code, but how everything fits together Tech I work with - Java (Spring Boot), Golang (Fiber), Python (FastAPI) - PostgreSQL, Redis, MongoDB, ElasticSearch, Cassandra, Weaviate - Kafka, RabbitMQ, Temporal, Airflow - Docker, Kubernetes, AWS (plus real-time protocols like WebRTC, MQTT, XMPP when needed) If your system is growing in complexity, slowing down, or becoming harder to evolve that’s usually where I can help the most. Let’s build something that lasts.
