AI & Web3 Consultancy

Khrystynych Innovations Inc

We help teams design, build, and ship production-grade AI and on-chain systems — from multimodal retrieval and intelligent automation to smart contracts on Ethereum and Solana, plus hands-on training for your engineers.

About

Khrystynych Innovations Inc is a boutique AI and Web3 consultancy. We partner with startups and established teams to turn promising prototypes into reliable, production systems — and to level up the people who maintain them.

Our work sits at the intersection of applied machine learning, on-chain engineering, and pragmatic software practice. We design multimodal retrieval pipelines, automate workflows with agents and LLMs, ship smart contracts and integrations on Ethereum and Solana, and run hands-on training programs tailored to your stack. No hype, no black boxes — just systems your team can understand, extend, and own.

Services

Multimodal RAG Implementation

Grounded answers over text, images, audio, and video.

We design retrieval-augmented generation systems that reason across modalities — so your models can cite the right passage, frame, or chart instead of hallucinating.

  • Ingestion pipelines for documents, images, audio, and video
  • Hybrid vector + keyword retrieval with evaluation harnesses
  • Chunking, embedding, and re-ranking strategy tuned to your corpus
  • Observability, guardrails, and cost controls for production

AI Automation Implementation

Agents and workflows that replace repetitive work.

We build agentic systems and LLM-powered automations that plug into your existing stack — from triage and drafting to multi-step workflows with human-in-the-loop checkpoints.

  • Workflow discovery and ROI assessment before any code is written
  • Agent orchestration with tool use, memory, and fallbacks
  • Integrations with your CRM, ticketing, data, and internal APIs
  • Monitoring, eval suites, and safe rollout behind feature flags

AI Training

Hands-on upskilling for your engineering team.

Custom workshops and coaching programs that take your engineers from curious to capable. We tailor the curriculum to your codebase, your stack, and the problems you actually need to solve.

  • Tailored curriculum covering prompting, RAG, agents, and evals
  • Live coding sessions against your real systems, not toy demos
  • Code reviews and pairing with senior AI engineers
  • Internal playbooks and reference implementations you keep

Web3 & Crypto Engineering

Production-grade smart contracts and on-chain integrations on Ethereum and Solana.

We design, build, and audit on-chain systems on Ethereum (EVM) and Solana — from escrow and marketplace contracts to wallet integrations and indexing pipelines. We bring the same engineering discipline to Web3 that we bring to AI: evaluation, observability, and safe rollout.

  • Smart contract design, implementation, and test coverage (Solidity on EVM, Rust/Anchor on Solana)
  • Wallet, signature, and transaction flows integrated into your product
  • Indexers, subgraphs, and event pipelines that keep your UI and analytics in sync with chain state
  • Security review, threat modeling, and prep for third-party audits
