WHAT I DO

Services

Four ways to bring me in: fixed-scope architecture audits, high-concurrency engineering sprints, autonomous AI agent pipelines, and fractional principal backend engineering.

01 / FIXED SCOPE

System Architecture & Bottleneck Audit

1–2 WEEKS

A rigorous diagnostic investigation into why your platform is slowing down, locking database tables, or failing during traffic spikes. I profile slow queries, trace distributed request bottlenecks, and deliver an actionable engineering blueprint.

What you get:

  • Ranked report of slow queries & locking hazards
  • Redis cache invalidation & queue topology plan
  • Security & multi-tenant isolation review
  • 60-minute technical walkthrough with your engineering team

02 / PRODUCTION BUILD

High-Concurrency Engineering Sprint

2–4 WEEKS

Bring me in to re-engineer one critical system bottleneck that is stopping growth: high-volume payment processing, asynchronous webhook ingestion, complex search indexing, or database sharding. Built for 10x throughput and sub-80ms response times.

What you get:

  • Refactored idempotent controllers & async job pipelines
  • Zero-downtime database migrations & index tuning
  • Automated load tests (k6/JMeter) verifying target concurrency
  • Complete integration test suite with CI/CD deployment hooks

03 / AI & AGENTS

Autonomous AI Agent Systems & RAG Pipelines

2–6 WEEKS

Moving beyond basic prompt wrappers. I design deterministic multi-agent architectures, function tool-calling routines, vector search embeddings, and fallback loops that operate reliably in enterprise production.

What you get:

  • Custom autonomous agent workflows with strict schema outputs
  • Vector database ingestion & chunked similarity retrieval
  • Token caching & rate-limit throttling protections
  • Telemetry logging for hallucinations and latency spikes
Architect your AI pipeline
04 / FRACTIONAL LEADERSHIP

Fractional Principal Backend Engineer

MONTHLY RETAINER

Principal engineering guidance without the executive overhead. I embed with your founders or senior team: reviewing architectural RFCs, running code governance, preventing costly technical debt, and mentoring developers.

What you get:

  • Dedicated weekly architecture & sprint design sessions
  • Asynchronous pull request reviews and security auditing
  • Direct Slack/Discord access for urgent architecture decisions
  • Guaranteed timezone overlap with European & US mornings

Not sure which of these it is?

Describe the bottleneck or scaling problem rather than the deliverable, and I will tell you directly which approach makes the most sense.
