Mechanical engineering student with a love for coding.
Mostly Rust, plus Python and JavaScript, with a soft spot for ClickHouse.

I'm open to freelance ClickHouse work. Things I can help with:

• Schema & table engine design (MergeTree family, partitioning, ORDER BY / primary key choice)
• Query and performance tuning: slow queries, PREWHERE, skipping indexes, projections, materialized views
• Ingestion pipelines and Rust/Python services on top of ClickHouse
• Migrations from Postgres or other databases to ClickHouse

What I bring:

• Running ClickHouse in production as the analytics backend of the Deadlock API
• Contributing to ClickHouse core (query execution, index analysis, type handling)
• clickhouse-antlr4: an ANTLR4 grammar for ClickHouse SQL

📩 Interested? Email me at raimannma@outlook.de.

I’m building and contributing across the Deadlock API ecosystem:

• deadlock-api/deadlock-api — Game Data & Analytics API
• deadlock-api/deadlock-api-ingest — public data ingestion
• deadlock-api/openapi-clients — generated clients from OpenAPI specs

• ValorantAPI — Python wrapper for the unofficial Valorant API
• rust-optimizer — black-box optimization in Rust using Tree-Parzen Estimator (TPE)

• Mechanical engineering student exploring systems, data, and performance.
• I enjoy building robust tooling, clean APIs, and automation around data flows.
• Rust first, but I’m comfortable in Python and JavaScript when it fits the job.
• Big fan of ClickHouse for analytics at scale.
