Andrei Nita

CTO who turns messy data orgs into investor-grade machines — 3× delivery, 60% cloud cost cut, 1→15 team built.

I've done this across VC-backed B2B SaaS companies from Series B to D — geospatial intelligence, AI platforms, subscription analytics. The pattern is consistent: fragmented tech, slow delivery, limited board visibility. The fix is always the same: clear architecture, the right data, and a team that executes reliably.

CTO for Data and AI-driven SaaS

I build lean engineering orgs, data platforms, and AI products that grow ARR and improve unit economics — for VC-backed and subscription businesses from Seed to Series D.

First 90 Days

My structured approach to delivering value quickly, building on the technical capabilities and proven impact results.

  • Map current architecture, data flows, and delivery bottlenecks.
  • Meet customers, GTM, and finance to understand value levers and pain points.
  • Establish basic visibility: ARR, churn, funnel, and platform health dashboards.
  • Define a lightweight technology and data roadmap tied to OKRs and commercial targets.
  • Set up a predictable delivery model (teams, rituals, metrics).
  • Prioritise quick wins (cloud cost cuts, key data fixes, or a focused AI feature).
  • Start delivering high-impact roadmap items.
  • Formalise data governance (access, quality, security, reporting).
  • Agree ongoing cadence with leadership (monthly management reporting, quarterly roadmap review).

Capabilities

Architecture that scales without surprises

  • Design cloud-native systems that handle 10× load without emergency refactors (AWS, Azure)
  • Migrate monoliths to event-driven microservices without halting delivery
  • Build data warehouses that serve both operational queries and board reports (Snowflake, Redshift)
  • Ship CI/CD pipelines that make weekly releases the default, not the exception
  • See real-world results from these architectural approaches.

Data that earns board confidence

  • Build pipelines from raw → investor-grade metrics in weeks, not quarters (Airflow, Fivetran, Snowflake)
  • Automate the finance and product reporting that consumes analyst time (Tableau, Power BI, Domo)
  • Deliver ARR, MRR, churn, LTV, and CAC dashboards that hold up in a Series B–D data room
  • Replace fragmented Segment and warehouse setups with a unified, auditable data model
  • Learn about my 90-day approach to data transformation.

AI that ships to production, not just pilots

  • Take ML models from notebook to production with monitoring and feedback loops in place
  • Build knowledge graphs and NLP features that become product differentiators (Neo4j)
  • Define the data foundation AI actually needs — before the model work starts
  • Bridge data science and engineering so neither team blocks the other
  • See AI implementation examples in my case studies.

Engineering orgs that don't need rescuing

  • Build delivery processes where predictability replaces heroics
  • Cut cloud spend 40–60% by treating FinOps as an architecture discipline, not a cost exercise
  • Set up data governance and compliance that satisfies auditors without slowing the team
  • Translate technology roadmap into board language — and back again
  • Read my point of view articles on engineering leadership.

"I build lean, accountable teams with clear ownership. Small orgs outperform larger ones every time. I've scaled from 1 to 15 and kept that ethos intact. I protect the team from noise so they can focus on the work that matters."

Selected Impact

Real results from applying the technical capabilities across different organizations. See my 90-day approach for how I achieve these outcomes, and explore more detail on the media & case studies page.
