Client work

Eight engagements, anonymized.

Contract engagements across infrastructure, platform, and product · NDA-bound, so clients are not named. The one exception is Iguazio, below, which appears under its own name because it was an employer engagement that is already public in the experience section of this site. Every number here is one that also appears there — nothing is rounded up for the occasion.

01

Production emergency: containing a $40K/day agent cost explosion

Client.
Late-stage platform, production multi-agent system.
Engagement.
Incident response · priced after triage.

The problem. A multi-agent pipeline in production began spending at a rate projected to exceed $40K per day — a $1.2M/month run-rate if left uncorrected — with no per-session budget controls and no circuit breaking at the tool-call layer.

What we shipped

  • Led triage and spend attribution first: per-agent, per-model, and per-tool cost mapping before touching the live system.
  • Shipped circuit breakers at the tool-call layer with per-agent and per-tool thresholds.
  • Enforced per-session spend caps, keyed to task type, at runtime.
  • Deployed retrospective governance: deterministic policy validation on every tool call, so spend is blocked before execution rather than reviewed after the bill lands.

Result

  • Projected $40K+/day burn contained within 72 hours of engagement start.
  • Zero recurrence since.
  • The same controls shipped into the client's standard deployment path.

02

Platform Design & Build: multi-tenant agent substrate

Client.
Six-plus fast-growing platforms, Series B to late-stage teams.
Engagement.
Fixed-scope projects, ~6 weeks each, delivered to production and handed to the client's team.

The problem. Platforms shipping agents to production were hitting the same walls: shared infrastructure without tenant isolation, no spend control, no memory layer, and release overhead that slowed every iteration.

What we shipped

  • Built the multi-tenant substrate agent systems run on — routing, memory, evaluation, and spend control — across AWS Bedrock, AgentCore, and Azure.
  • Built Go, Python, and TypeScript middleware plus Azure DevOps deployment templates for four distributed engineering teams.

Result

  • Delivered to production at 250-450 concurrent agent instances, then handed to the client teams.
  • Release-cycle overhead reduced by roughly 40%.

03

Reliability program: SLO frameworks for three platforms

Client.
Three client platforms running multi-agent systems in production.
Engagement.
Reliability advisory · two quarters.

The problem. Teams were operating production agents without agreed reliability targets — every incident was argued over opinion instead of data, and improvements could not be measured.

What we shipped

  • Defined SLO frameworks on task completion rate, mean tool calls, hallucination escape rate, and end-to-end latency.
  • Tied error budgets to each objective, with agent trace instrumentation feeding the dashboards.

Result

  • SLO compliance improved from 71% to 96% over two quarters.

04

Retrieval and governance at scale

Client.
Platform running heavy tool-use agents in production.
Engagement.
Audit and build · production hardening.

The problem. A retrieval and governance layer that had grown ad hoc: no deterministic validation on tool calls, no visibility into what agents were actually invoking, and no evidence of enforcement for security review.

What we shipped

  • Audited the retrieval stack on Pinecone and OpenSearch and rebuilt the ingestion and query paths.
  • Enforced deterministic policy validation on every tool call, with zero known bypasses across deployments.

Result

  • 1.8M+ tool invocations running under policy validation.

05

LLM cost reduction program

Client.
Portfolio of client platforms across the advisory engagements.
Engagement.
Cost optimization program · FinOps.

The problem. The same integration mistakes repeated across client codebases: context re-injected without caching, token-heavy integrations, and infrastructure patterns that multiplied spend.

What we shipped

  • Refactored Anthropic SDK, n8n, and Copilot Studio integrations around token optimization, prompt caching, and low-infrastructure patterns.

Result

  • $200K/yr aggregate reduction in cloud and LLM spend across the portfolio.

06

Data and ML platform standardization

Client.
Two client platforms with classical ML workloads.
Engagement.
Data platform standardization.

The problem. Data lakes and model registries that had diverged across platforms, making model lineage and dataset governance inconsistent.

What we shipped

  • Standardized data lakes and model registries across both platforms, integrating Databricks and Domino Data Lab with existing workloads in scikit-learn, PyTorch, and TensorFlow.

Result

  • One data and model lifecycle across both platforms.

07

Real-time prediction-market trading system

Client.
Proprietary high-frequency trading firm · remote.
Engagement.
Systems engineering · Jan. 2026 - Jul. 2026.

The problem. A production trading system for prediction markets pulling live data from centralized exchanges and on-chain sources, with hard risk controls and sub-10ms peak latency requirements, trading real capital.

What we shipped

  • Designed and ran event-driven Python and Rust pipelines holding sub-10ms latency at peak load.
  • Designed the live risk-control layer: position limits, daily loss limits, and slippage checks enforced on every order.
  • Built statistical models of market order flow to detect volatility clustering, and used them to size trades and set execution pace under fast-moving conditions.
  • Implemented Kelly-criterion position sizing that scales exposure to model confidence.
  • Maintained the research pipeline: historical backfill, detector-faithful backtesting, walk-forward validation, and automated signal outcome labeling.

Result

  • Execution slippage cut by 14%.
  • Zero limit breaches while trading real capital.

Iguazio AI: inference platform engineering at scale

Client.
Iguazio AI (employer engagement · public on this site) · remote contractor.
Engagement.
Jun. 2021 - Mar. 2023.

The problem. Enterprise NLP and computer-vision inference workloads on a monolithic FastAPI service: 18-minute cold starts, a 900ms+ p99 on core analytics queries, and no canary rollout path.

What we shipped

  • Deployed and operated a multi-GPU Triton Inference Server cluster with dynamic batching and model quantization, with inference SLOs and Prometheus/Grafana alerting runbooks for OOM failures.
  • Decomposed the monolith into event-driven microservices on Docker, PostgreSQL, and Kafka.
  • Owned schema and indexing strategy for behavioral analytics datasets across three product teams; redesigned indexes and materialized views.
  • Engineered GitOps CI/CD with GitHub Actions and ArgoCD, automated health checks, and canary rollout policies.

Result

  • Cold-start deployment time from 18 minutes to under 4.
  • p99 query latency from over 900ms to 120ms.
  • 99.9% uptime sustained across production containerized environments.
