AI Engineer & Technical Lead | LLM & Agent Systems
[open contact info](look above in the "contact info" section) | github.com/KostiantynBk | Spain / Remote

AI engineer building Python backends, multi-agent systems, voice agents, RAG pipelines, and business automation.
Commercially shipped trading-platform services and led architecture for a multi-agent product — specs, interface
contracts, and review for a distributed team. Same patterns apply outside trading: ops, support, and customer-facing
workflows.

EXPERIENCE

Technical Lead / Project Manager - AI Agent Systems May 2026 - Sep 2026
Mediaverse Pte. Ltd. | Independent Contractor (Promoted from AI Systems Developer) | Remote
Owned architecture for a multi-agent trading platform: agent roles, tool boundaries, backend services, and the
path from research signals into order/journal workflows.
Turned trading-domain requirements into specs and interface contracts; set implementation order and reviewed
Python changes for a distributed team.
Ran delivery in Monday.com with MCP so coding agents could create, update, and close tasks from the repo
instead of a stale board.
Introduced a Hermes agent with a memory layer so new joiners only retrieved project context they were allowed
to see (NDA-gated).

AI Systems Developer Mar 2026 - May 2026
Mediaverse Pte. Ltd. | Independent Contractor | Remote
Built Python services and agent workflows for a multi-agent trading platform, wiring LLM tools to
market/application data and automation steps.
Translated desk requirements into backend components and specs for ingest, research, and agent hand-offs.
Implemented statistical and ML utilities with NumPy, SciPy, statsmodels, and scikit-learn for residualization,
regressions, and time-series checks used by agent tools.
Worked spec-to-PR with Codex, Claude Code, and Cursor, using Perplexity for research against written contracts.

Backend Engineer Sep 2024 - Feb 2026
Voxum | Independent Contractor | Hybrid
Built FastAPI services for strategy automation: live market ingest, signal workflows, and order/journal persistence.
Ingested market data over WebSocket and FIX with asyncio; published events on Redis Streams and cached hot
state in Redis.
Stored ticks/bars in TimescaleDB and orders in Postgres; kept research datasets as Parquet on S3 and queried
them with DuckDB/Polars.
Packaged services with Docker, deployed on Kubernetes, and added Prometheus/Grafana dashboards and alerts
for ingest lag and service health.
