Nobody writes about this. Maybe because the people who live it are too busy being the only ones who can fix the WiFi.
There's a specific kind of loneliness that has no name yet.
It's not the loneliness of working remotely. It's not the loneliness of being an introvert in an open-plan office. It's sharper than both of those and quieter.
It's the loneliness of being the only developer in a company full of people who don't speak your language — and never will.
You didn't notice it at first
The job sounded exciting. A real company. Real problems. And you—the person who could actually build things—walking in like someone who finally has superpowers in a world that needs them.
The first few months felt like that. You shipped things. People were impressed. Someone in a meeting called you "our tech guy/girl", and you smiled because it felt like belonging.
Then, slowly, quietly, you started to notice.
There was no one to review your pull requests. Not because people were lazy — but because nobody could. You merged your own code. You reviewed your own architecture decisions. You Googled your own doubts.
You started having conversations with yourself dressed up as documentation.
The weight of being the only one who knows
Here's what nobody tells you about being the sole developer:
You never get to be junior again.
In a team, you can say, "I'm not sure; let me check with someone." You can say, "I think we should do X, but I want a second opinion." " You can be wrong in a safe container where someone catches you.
When you're alone, every decision is final until it catastrophically isn't. The codebase becomes a direct mirror of your blind spots — and you can't see your blind spots. That's what makes them blind spots.
The worst part? You can't tell anyone at work. Because to them, you're the expert. The wizard. The one with the answers. Admitting uncertainty feels like the whole illusion shatters.
So you carry it. You carry the uncertainty, the technical debt you made at 2am when something was on fire, the architectural decisions you're not proud of, and the library you chose because it was familiar, not because it was right.
You carry it alone.
The meetings. Oh, the meetings.
You sit in a room where someone is explaining a problem using words that mean something different to you than to them.
"Can't we just make it automatic?"
"How long would it take to just connect the two systems?"
"We had something like this at my last company; they built it in a weekend."
And you smile. Because explaining why it's not that simple requires first explaining what a system even is, what an API is, and what "connecting" two things actually means at 3am when the data formats don't match and one of the services has been deprecated and the documentation is a lie.
You smile. You say, "I'll look into it." " You go back to your desk and stare at the ceiling for ten minutes.
This isn't frustration at your colleagues. They're smart. They're good at what they do. This is something else — the particular ache of expertise becoming isolation.
The more you know, the more alone you are in knowing it.
You become the IT department by accident
At some point — and you won't remember exactly when — you became responsible for things nobody assigned you.
The printer. The WiFi. "My laptop is slow." "Can you look at this spreadsheet? Something's wrong with the formula." "We need a new tool for X; can you find one?" "Can you just automate this thing we do every Tuesday?"
You say yes. Because you're kind. Because it's easier. Because saying "that's not really my job" when you're the only technical person feels like abandonment.
But something quietly breaks inside you each time. Not because the tasks are beneath you. But because each one is a reminder: you are not here as a peer. You are here as infrastructure.
The thing that actually hurts
It's not the workload. It's not even the loneliness in the textbook sense.
It's the absence of intellectual companionship.
There's a specific joy that exists only when someone else deeply understands what you're building. When you can say, "I used an event-driven architecture here because—", before you finish the sentence, they're already nodding, already pushing back, already making it better.
That conversation. That specific aliveness of two minds on the same problem.
You haven't had it in months. Maybe years.
You've had good conversations. Friendly conversations. But not that conversation. The one where you leave feeling like your brain grew.
So instead you go to Twitter/X. You go to dev.to. You go to Hacker News and read comment threads at 11pm not because you're avoiding sleep but because you're desperately, quietly, trying to feel less alone in the thing you care most about.
What it does to you over time
It makes you doubt yourself in strange ways.
Not the obvious "Am I good enough?" kind of doubt — though that's there too. But a subtler erosion. You start to wonder if the way you think about problems is normal. You have no reference point. No colleague who builds things like you do.
You over-engineer sometimes, chasing elegance that nobody will ever see. You under-engineer other times, cutting corners you're ashamed of because there's no one to hold the standard with you.
You develop strange habits. Talking to rubber ducks. Writing READMEs with the exhaustive detail of someone who fears being misunderstood.
Commenting code is not for the next developer but as a kind of message in a bottle, proof that you were here, that you thought carefully, and that you weren't just someone who kept the lights on.
But here's the thing
There are thousands of us.
In insurance companies and law firms and small NGOs and family businesses and local councils and restaurants that needed an app. Everywhere that the world runs on software but doesn't quite run as software yet.
We are the quiet layer. The ones who translated "we need a thing" into a thing, alone, and then went home without anyone to debrief with.
And for some reason—maybe because dev culture is so focused on startups and big tech and 10x teams and Silicon Valley origin stories—nobody writes about us.
Our loneliness doesn't get a conference talk. Our specific exhaustion doesn't get a Medium think piece. Our wins are invisible because there's no one internally who understands what winning even looked like.
To the only dev in the room
Your instinct to Google things isn't weakness. It's what self-reliance looks like in practice.
The code you wrote alone, that nobody reviewed, that's been held up in production for two years — that counts. That's real. That took courage even if nobody clapped.
The meetings you sat through smiling, translating the untranslatable — that's emotional labour nobody put on your job description, and you've been doing it quietly without credit.
And the longing you feel for a peer, for someone who gets it — that's not neediness. That's just being human and loving something deeply enough to want to share it.
Are you (or were you) the only dev at your company? Tell me what it was actually like in the comments. I promise I'll read every single one.
