I’m happy to start with a small task or paid test project to build trust 🤝

20-Year Seasoned Software Architect | Java Specialist | Multi-Industry Expert Hello! I'm a senior software developer with two decades of hands-on experience designing and building enterprise-grade applications across diverse industries—finance, healthcare, e-commerce, IoT, and SaaS platforms. My core philosophy is simple: every business has unique challenges, and the best solution isn't always the most trendy one—it's the one that fits your specific needs perfectly.

I turn messy data into systems people can rely on. Six years building warehouses and pipelines for a bank, now taking on selected projects here. What I can do for you: Build pipelines that survive contact with reality. Incremental loads, correct backfills, no silent duplicates when a source resends the same records. Airflow, dbt, Python. Design a warehouse or a data mart from scratch. I built one covering 7.6 million companies with 112 attributes, assembled from around 60 separate sources, and I keep it running daily. Make slow queries fast. I read execution plans instead of guessing. Partitioning, storage format, join order, indexes. Cut storage cost. On one project I moved 1.6 TB of rarely used data out of an expensive warehouse into Parquet, where it now takes 43 GB. Get data out of anywhere. Public registries, websites, APIs, and other people's databases: MySQL, MS SQL, MongoDB. Build internal tools your team will actually use. I made a Streamlit app where a sales team builds its own queries against the warehouse, enriches spreadsheets and submits requests with validation, running in Kubernetes with proper auth and releases. Stack: SQL, Python, Oracle, PostgreSQL, Greenplum, ClickHouse, DuckDB, Airflow, dbt, Debezium CDC, Pentaho, StreamSets, Docker, Kubernetes, Parquet, S3. Tell me what you are trying to build and I will say honestly whether I am the right person for it.

I'm a data engineer who builds the platform your data lives in, so your team stops waiting on reports and starts asking questions. Whether you need a warehouse stood up from scratch, dbt models on the Snowflake or Databricks you already run, or data pulled out of a legacy system nobody wants to touch, I can help. What I build: - Warehouses on Snowflake, Databricks, or Postgres, plus the ingestion to fill them - dbt models and a semantic layer, so a metric means one thing everywhere - Pipelines and orchestration in Python, SQL, and Dagster - Contracts, tests, and lineage written as I build, so the numbers hold up - Integrations with legacy and undocumented systems, including old MySQL and PHP apps - Reporting your team actually opens on a Monday, in Power BI or the BI tool you use - AI agents on top of the platform, scored against real questions with known answers Background: years of data engineering at companies like CNN and Whatnot. I now run Wide Open Tech, where we operate the production software behind ShelfGenie and 101 Mobility, two national franchise networks used daily by 500+ operators across the US and Canada. How I work: plan, build, review, ship, the same way every project. You approve the plan before I write code and the merge before it ships. Everything is deployed in your own cloud, on your own stack, and it stays yours. Full project management from start to finish. I keep communication regular and direct, so you always know where things stand.

Are you struggling with a legacy PHP monolith that slows down feature delivery? Or perhaps you need to scale your backend to handle millions of daily events? I am a Senior Backend Engineer with over 12 years of commercial experience designing, building, and optimizing scalable web applications. My core expertise lies in the PHP ecosystem (with ~7 years dedicated to Symfony) and modern architectural patterns like Event-Driven Architecture (EDA), Domain-Driven Design (DDD), and microservices. Here is how I can help your business: Legacy Modernization: Safely migrating monolithic systems (Zend/CodeIgniter/Yii) to modern Symfony ecosystems with zero downtime using the Strangler Fig pattern. Highload & Data Pipelines: Building infrastructure to process thousands of RPS and millions of daily events using Kafka, RabbitMQ, and ClickHouse. FinTech & Security: Architecting PCI-DSS compliant B2B platforms, implementing complex KYC/AML compliance pipelines (fuzzy matching), and developing robust transaction/billing logic. I believe in pragmatic engineering. I don't just write code; I choose the right tools for the job, balance microservices design to avoid network latency, and deliver maintainable, test-driven architectures. Core Tech Stack: PHP (5.6 - 8.x) | Symfony (2.4 - 7.x) | Lumen MySQL | ClickHouse | MongoDB | Elasticsearch Kafka | RabbitMQ | Redis Docker | AWS | Git | CI/CD If you need a reliable engineer to safely refactor your core product, build secure financial logic, or set up high-performance data pipelines, let’s connect and discuss your project.

Senior .NET Backend Engineer I help FinTech and enterprise teams build backend systems that can actually handle regulation, scale, and security pressure without falling apart. Tech stack: C#, .NET Core, ASP.NET Core, Entity Framework, Dapper, SQL Server, ClickHouse, RabbitMQ, Keycloak, Microsoft Entra ID, OAuth2/OIDC, Docker, Azure, Cursor & Claude Code (AI-assisted development). For the past 6+ years I've worked inside international remote teams (Vienna, London) building things that matter when they break: payment pipelines, identity & access management (Keycloak, Microsoft Entra ID, custom SSO), and crypto wallet integrations (Fireblocks MPC) where there's zero room for "it usually works." What I'm good at: Turning messy legacy monoliths into clean, modular architectures (Vertical Slice, DDD) — without stopping the business to do it Designing IAM and SSO setups that secure multi-tenant platforms without slowing teams down. Building audit and compliance logging that passes external EU regulatory audits, not just internal checks Async, event-driven backends (RabbitMQ, retry/DLQ handling) that don't quietly lose messages under load I also work daily with AI-assisted development (Cursor, Claude Code, Copilot), which means I move fast without cutting corners on architecture or code quality. If you need someone who can own a backend system end-to-end — design, build, harden, and explain clearly in English the whole way — let's talk.
