Small technical team
One developer carries all technical responsibility
If my dev is out sick for two weeks, I don't even know what's happening in our own code.
One developer concentrates all technical responsibility at your company. Risk isn't theoretical: illness, departure, vacation, burnout. You don't need a second full-time hire, you need continuity, perspective, and peace of mind when production is down and your main developer doesn't answer.
One day a week structures deep work; in parallel, we frame day-to-day value, gradual backup, and dependable coverage (reachable on weekdays, urgency and weekends agreed up front).

Peace of mind
Reachable and dependable, even at one day a week
In this situation, it's often not the most visible point, but the one that matters most to leadership: knowing who answers when production is down and your main developer is overloaded or unreachable. One day a week structures deep work; reachability and emergencies are framed separately from day one.
Reachable throughout the week
You don't wait for the scheduled day to talk: I stay reachable on Slack or the channel you already use. Questions, trade-offs, early signals: we keep the thread without turning every ping into a meeting.
Emergency when your main developer doesn't answer
If production breaks and your main developer can't take the call, I step in under an emergency frame we define together: scope, priority, response time, with a clear commitment on what triggers intervention.
Weekends: agreed windows and limits
Weekends aren't « off limits » by default: we can agree windows and limits (time bands, incident types, escalation). Everything is written up front so no one has to guess whether « this counts » as an emergency.
What leadership gains
Less mental load when all tech rests on one person: dependability, visibility, and backup without hiring a second full-time developer or micromanaging your lead.
The risk
Bus factor, in practice
Your main developer stays owner of the code and decisions. My role isn't to compete: it's to reduce single-point dependency, speed up reviews, and be the reliable backup when they're away, overloaded, or unreachable in an emergency, because we prepared together.
If you're preparing a first hire or product leadership instead, see Post-funding: before your first full-time developer and Need a PM or PO, without full-time.
What we set up
Day-to-day value and gradual backup
Learning the codebase
Light documentation, tour of critical areas, access and conventions, without reading every line. Goal: intervene on essentials within weeks, not duplicate your lead's head.
Value from the first weeks
Architecture reviews, unblocking, prioritization, targeted debt. Your dev gets a senior peer one day a week, not an auditor who shows up once a year.
Light backup, not a clone
We write what's covered in an intervention (fixes, deploys, level-2 support) and what triggers an emergency. You know what to expect: no black box when your developer is overloaded or away.
Reachable on weekdays, off mission day
Mission day structures deep build; in between, I stay reachable on Slack or your channel for day-to-day topics. No waiting until the next slot for a trade-off or early signal.
Vacation and agreed on-call
When your developer is on vacation, we activate a framework we've already tested: channels, incident priority, availability windows. On-call agreed in advance, not Monday-morning improvisation.

How I build
Technical foundations
Backup on your existing stack: we check early whether I'm aligned with your languages, frameworks, and tooling, then reviews, runbooks, and prioritization without disrupting your primary developer's day to day.
Objections
Common questions
I frame it as backup for them: less solo pressure, faster reviews, someone who knows the context when they need time off. Leadership clarifies the lead keeps ownership; I'm not there to take their job.
Often yes, for gradual knowledge and a safety net, with clear scope. It's not a second full-time role: it's insurance and acceleration. Mission day structures deep build; in between, reachability and emergencies follow a frame defined up front, not waiting until the next slot.
We clarify that in the first conversation: languages, frameworks, hosting, debt level. My deepest hands-on experience is in JavaScript and PHP ecosystems (Laravel, React, Next.js, Vue, WordPress, Node). On another stack (Python, .NET, Go, etc.), I can often still bring architecture, reviews, prioritization, and emergency backup; hands-on build depends on context, and we decide without vague promises.
Repo and tool access per your policy, NDA if required. I don't publish your code: work stays in your systems. We define who sees what on the first conversation.
The agreed rhythm (e.g. one day a week) structures deep work, not whether you can reach me.
Ongoing, I make time to reply on Slack or your preferred channel. Out-of-scope emergencies go through the shared urgency frame we define together (scope, priority, response time).

All technical responsibility on one developer? One call is enough to see if one day a week, with dependable emergency coverage, gives you margin without disrupting your team.
