CTO Hands-on

Why a CTO Still Needs to Get Their Hands into the Code

Being a CTO today doesn’t just mean leading a team, defining a technological vision, or negotiating budgets. It also means maintaining a solid connection with the raw material of our work: software. Being hands-on doesn’t mean writing code every day, but preserving the ability to “feel” the system, understand its dynamics, and recognize what is simple, what is difficult, and what is dangerous.

This is an awareness that radically changes the way we lead a technical organization.

Maintaining the ability to know the creature without diving too deep into operational detail. You don’t need to be the best coder on the team, but you must know enough to understand how technological and architectural choices influence business, costs, performance, and quality.

Knowing your system — both from a code and infrastructure perspective — enables more accurate decisions, better evaluation of impacts and priorities, and more pragmatic team guidance. A CTO who keeps a concrete technical perspective is more credible, quicker at identifying risks, and far more effective in building a sustainable technological strategy.

What Happens When You Don’t Know the Implementation Logic

When a CTO loses touch with technical reality, three things happen:

• Estimates become abstract: not knowing what’s “under the hood” leads to misjudging complexity and timelines.
• Delegation becomes blind: delegation is necessary, but without technical awareness it becomes dangerous — solutions, trade-offs, and risks are evaluated poorly.
• Authority is weakened: the team senses immediately when leadership doesn’t truly understand what it’s coordinating. This reduces trust, engagement, and the quality of discussions.

A CTO doesn’t need to know everything, but must know how to ask the right questions — and this is only possible when the implementation foundations are understood.

What to Know

A strategically detailed understanding is required of:

• Application architecture: patterns, modules, critical points, sensitive flows.
• Scalability principles: where bottlenecks form, what trade-offs exist, what structural limits are present.
• Technology stack: languages, frameworks, dominant paradigm, historical choices and motivations.
• Infrastructure and DevOps: deployment, pipelines, monitoring, alerting, costs.
• Code quality: not style, but structure, maintainability, and coherence.

You don’t need to intervene in every area, but you must understand how everything fits together.

When to Stop

A CTO must stop before:

• becoming a bottleneck;
• personally solving operational issues that the team can handle;
• turning into a “super developer” who centralizes decisions and blocks team growth.

The right boundary is clear: step in to understand, not to replace.

How Much Time to Dedicate

Not much is needed:
4–6 hours per month of hands-on work is enough to stay aligned.

Some practical examples:

• opening the codebase and reading critical modules;
• pairing with a developer during a complex refactoring;
• reviewing an architecture or a strategically important PR;
• debugging a major incident to understand its nature.

These are not developer activities: they are technical leadership activities.

What You Gain

Maintaining a hands-on profile brings concrete advantages:

• Stronger decisions: based on real understanding, not intuition.
• A stronger team: because people feel understood, not “managed from above.”
• Faster recognition of problems, risks, and opportunities.
• Credible leadership: the team knows you speak with real awareness.
• A more integrated vision between business and technology.

A hands-on CTO isn’t a CTO who codes:
it’s a CTO who understands what’s really happening inside their platform.

Having clean hands is nice. But having hands dirty with code — every now and then — makes a CTO better.
