Poplavsky Solutions

AI engineering, without the hype

Poplavsky Solutions is a founder-led AI engineering studio. Every project is a production system, not a proof of concept.

Strategy and advisory for companies starting their AI journey. On-prem deployment for companies whose data can’t go to the cloud. Inference performance and cost optimisation for companies whose AI bill is out of control.

Hands-on engineering, end to end. Fixed-fee where it makes sense. No demos that never ship.

AI Strategy & Technical Advisory

Senior AI thinking — before, during, and after the build.

AI Strategy Sprint

A written roadmap before you commit to a build. Capability and opportunity assessment, use-case prioritisation with ROI estimates, technical architecture recommendations, build-vs-buy decisions, and a 6-month implementation roadmap.

Technical Architecture Review

A senior second opinion for teams already mid-build. Review of current architecture and tech choices, identification of risks and dead-ends, and recommendations for stack changes with effort/impact estimates.

Fractional Head of AI

Senior AI leadership one to two days a week, without a full hire. Strategic direction, hiring support, vendor decisions, stakeholder communication, and hands-on architectural input on critical builds.

Hourly Technical Advisory

Ad-hoc deep-dive questions: model selection, infrastructure tradeoffs, evaluation strategy, specific technical problems. Booked in 10-hour blocks.

Where we help

  • “We want to use AI but don’t know where to start.”→AI Strategy Sprint
  • “We’re mid-build and want a senior second opinion.”→Technical Architecture Review
  • “We need AI leadership but can’t justify a full hire yet.”→Fractional Head of AI
  • “We have a specific technical question and need an expert for a few sessions.”→Hourly Technical Advisory

End-to-end AI Systems

Complete AI systems, architecture to production — deployed on-prem when your data can’t go to the cloud.

On-prem Readiness Assessment

For prospects unsure if they need on-prem or how to scope it. Data sensitivity and compliance review, use-case prioritisation, hardware and infrastructure sizing, model recommendation, and an implementation roadmap with cost estimates.

Full On-prem Deployment

Hardware specification and procurement support, model selection with fine-tuning where it adds value, inference stack deployment, RAG over internal documents, integration with existing systems, monitoring and security, and team training with handover documentation.

Operations Retainer

For clients post-deployment who want ongoing monitoring, model updates, and architecture evolution. Sold only after a completed deployment.

What we deploy

  • LLMs, VLMs, and computer vision models on your infrastructure
  • RAG systems over internal documents and knowledge bases
  • Inference stacks (vLLM, SGLang, NVIDIA Triton) tuned and profiled for your hardware
  • Integration with existing backend systems
  • Monitoring, security, and compliance documentation

Performance & Cost Optimisation

Faster inference, lower bills — throughput, latency, and cost-per-token are one engineering problem.

Performance & Cost Audit

A pure diagnostic. Full analysis of prompt patterns, model selection, and token usage by feature. Caching opportunity analysis, model-routing recommendations, prompt-compression review, RAG retrieval efficiency, and a serving-stack review: engine configuration (vLLM, SGLang, NVIDIA Triton), quantisation, KV-cache and batching behaviour, and GPU utilisation profiling. Delivered as a prioritised written roadmap with savings estimates and a working session with engineering and finance.

Audit + Implementation

Audit included, plus implementation of the top three to five highest-ROI items. Before-and-after measurement with a monitoring dashboard, code handover and documentation, and a 2-week stabilisation period.

Performance Retainer

Continuous cost and architecture work for teams who want someone watching the bill. Monthly cost analysis and recommendations, ongoing prompt and model optimisation, pre-launch cost review for new features, and vendor-negotiation support. Sold only after a completed implementation engagement.

How we work

1. Understand the real constraints. Every engagement starts with the facts: your infrastructure, data, compliance, team capacity, deadlines, current AI spend. The constraints shape the work.

2. Design the right approach. Whether it’s a strategy roadmap, a deployment architecture, or an optimisation plan — the design fits your actual environment, not an idealised setup.

3. Deliver against measurable outcomes. Fixed-fee scope where it makes sense, real deliverables, and production standards from day one. No slide decks pretending to be systems.

4. Hand over for long-term ownership. Documentation, team enablement, and the context you need to operate, evolve, and maintain the work after we step away.

What clients say

LD4B
“Alexander built us a self-hosted AI system for scientific analysis of our manufacturing data — nothing leaves our infrastructure, and our engineers run it without any Python. What used to take days of manual Excel work is now a single command, with sharper insight than we could produce by hand.”
Andrei AndryieuskiCEO, LD4B
Ironhack
“Alexander designed and delivered the Data & AI course for Ironhack’s partnership with Azerbaijan’s education initiative for students. The material was aligned with latest industry standards, students stayed motivated throughout. A reliable, senior partner for AI education.”
Gonzalo ManriqueCo-Founder, Ironhack
