Case context

Overview

After product-market fit, Smartjobr needed technical strategy for the next growth phase. I advised on technology selection, team building, architecture decisions, and scaling direction without pretending to be a full-time CTO layer.

The value was decision quality: which technical risks needed visibility first, which team capabilities were missing next, and which platform choices could support growth. Next.js/PWA, React/TypeScript, Node.js, AWS, PostgreSQL including database functions, delivery, and operations were reviewed together with the AI matching context as one product and platform picture. The fractional model kept advisory close to the bottlenecks without adding unnecessary management weight.

Responsibility

Activities

  • Technical strategy advisory: Assess architecture decisions, technology choices, and scaling options
  • Risk mitigation: Make technical risks, security/privacy questions, and growth risks visible
  • Team scaling: Clarify hiring strategy, missing capabilities, and useful team shape
  • Leadership advisory: Connect technical direction with business model, product maturity, and investment logic
  • Fractional CTO model: Regular decision and sparring formats without a fake full-time role
  • Platform readiness: Review performance, scalability, and user experience against the next growth phase
  • Operations readiness: Review delivery, monitoring, operations, and team capability as part of scaling decisions
  • LLM-assisted work: used ChatGPT early in daily work for research, decision sparring, and copy, as far as the models of that time were already dependable for it

Operating mode

Methodology

  • Fractional CTO model: Focused sparring, decision support, and clear follow-ups instead of permanent role presence
  • Iterative advisory: Short feedback loops, fast reassessment, and focus on the most important current bottleneck
  • Strategic alignment: Keep technology, product, business model, and team capability in one decision picture
  • Risk-based approach: Name risks early, make options visible, and limit investment before confidence is high
  • Growth-focused: Prioritize scalability, hiring, and platform readiness along the next growth phase

The tools are not the point by themselves. What matters is which system layers had to work together.
