What we deliver
What we build.
Every engagement is principal-led: architecture, implementation, and delivery handled by a senior engineer who stays on the project from the first call to production.
Delivery Partner for Consultancies & Agencies
You own the client relationship; we architect and build the production system behind your engagement. White-label is standard, and NDAs and non-solicitation terms are routine for us.
Custom Software & Modernization
Web and mobile applications built around your workflows, customers, and data models — plus the event-driven automations, API integrations, and legacy modernization that clear tech debt without disrupting mission-critical users.
Client work
Franklin Logistics (franklinlogistics.ca) - custom courier ordering platform: quote engine, Stripe payments, driver dispatch, carrier-compliant SMS notifications. From signed agreement to live customer orders in under a month.
“Igor never simply delivered what we asked for—he consistently challenged us to think bigger. He offered thoughtful recommendations, creative solutions, and valuable insights that elevated our project far beyond what we had originally imagined. We wholeheartedly and without hesitation recommend him.”
AI delivery
AI systems that ship with guardrails.
We build production applications on the OpenAI and Anthropic APIs — generation pipelines with deterministic validation, human-review approval workflows, PII protection, and full audit trails — on top of the reliability engineering that keeps customer-facing software working when external services aren’t.
Deterministic validation
Model output is checked against rules and schemas before anything moves downstream.
Human-review gates
Approval workflows so a person signs off before AI output reaches a real customer.
PII protection & audit trails
Sensitive data handled deliberately, with a full record of what was generated and approved.
Reliability engineering
Queues, retries, and fallbacks underneath, so provider hiccups don’t become outages.

FAQ
Answers to the most common questions from new partners.
- What types of software projects do you take on?
- Production AI systems, custom internal tools and client portals, workflow automation and integrations, and product MVPs. We also build the production system behind consultancy and agency engagements.
- Who actually does the work?
- A senior engineer — the principal. The person on the first call is the person shipping your system. No handoffs, no account layer in between.
- Do you work white-label with consultancies and agencies?
- Yes — you keep the client relationship and the brand; we build. NDAs and non-solicitation terms are standard for us.
- How quickly can we start?
- Contract workstreams start within days. Scoped builds kick off in about a week, once scope and access are settled. Recent engagement: signed contract to first production release in 11 days.
- How does pricing work?
- Engagements are structured around project milestones or retainers, following a discovery call that validates scope, risks, and timeline before anyone commits to a number.
- Do you work with existing engineering teams?
- Yes. We integrate with your in-house engineering, product, and design people to add senior capacity — working in your repos, your pipelines, and your review process.
