how to get a tech job in 2026
- never ever use a job board
- dm/email people directly
- don't use AI to write the email
- build something with the company tech publicly
- write about the company publicly
- go to conferences and meet people from the company
- github doesn't matter anymore
- create educational content about the company tech
- make sure people recognize you when you apply
- develop some social skills
- if startup dm the founder
- everyone is looking for technical people with distribution
- develop a brand
- move to the US (SF/NY)

🚨 BREAKING: LAGOS LIFE IS EXPLODING
The numbers are getting ridiculous 😭🇳🇬
👑 365,192 total players
🟢 33,954 players online right now
🔥 586,933 visits today
🌍 2,095,296 all-time visits
And yes, you can literally watch the numbers climb LIVE, updated every 30 seconds.
Watch it live: lagoslife.ng/stats
The numbers don’t lie. Lagos Life is moving. 🥂👑
I grew up playing The Sims 3 and always wondered what it would be like if the Sims lived in a world inspired by ours.🤷🏽♀️
Then I saw @eureka_seamless riding a danfo through Lagos, and it sparked an idea: Lagos Life Sims.
Take a look around. Who knows, you might make a new friend in the Sims world.

I have a $20 VPS on Hetzner hosting more than 10 services and still counting….
Services easily managed with dokploy….
Built all images via GitHub action and trigger dokploy deployment to put the image in my container…
And connected all my domains to the services.
Life has never been easier

If or when you join those banks, you’ll understand why their systems are the way they are.
Even if you join as VP of Engineering or CTO, good luck convincing management to green-light a rewrite of legacy software that helps the bank declare billions in revenue every quarter.
By the way, a rewrite is usually attractive until you have lived through one.

for everyone wondering how zero-delay tracking is even possible on an $8 chip:
it is all thanks to the Kalman filter.
this 1-minute clip from Steve Brunton perfectly explains why it works (full lecture in reply)
instead of just observing a target, it mathematically predicts where it will be in the next millisecond.
here is what happens under the hood:
- balances physics of motion against noisy camera data
- corrects the trajectory instantly
- moves the robotic arm before the next frame processes
this is the exact same math used in rockets and autonomous driving, stripped down for a cheap microcontroller.
this creator just built a zero-delay auto-aim system on an $8 microcontroller
he deployed a custom local AI algorithm on a cheap ESP-32 to track human movement with absolute 0-pixel accuracy.
the system completely eliminates standard computation delay. it processes the bounding box and moves the sniper reticle instantly, locking onto the target in real time. the next step is hooking it up to a physical robotic arm.
it proves you don't need a massive GPU rig to run complex computer vision.
1. runs locally on a microcontroller
2. local AI inference for zero latency
3. 100% targeting precision
when an eight-dollar chip can track movement with zero latency, AI becomes dangerous local infrastructure. this article breaks down exactly how the ESP-32 is powering this physical hardware shift.

I am hiring Rust engineers!
We’re an early stage startup backed by some of the best institutions in the prediction market space,
If you care about highly performant and correct software, prediction markets or trading I would love to chat.

What if your production engineer never slept?
That's what we've been building at @ launchverse_.
Meet Helix; an autonomous cloud engineer.
You assign a task. Helix does the engineering.
• Clones your repository
• Spins up an isolated sandbox
• Reproduces bugs and infrastructure issues
• Troubleshoots and writes fixes
• Validates everything through rigorous testing in its own SSH-enabled sandbox with outbound network access via the Helix egress proxy
• Opens a GitHub PR and merges after your approval
• Deploys to @launchverse_ infrastructure and provisions a live domain
And it doesn't stop there.
Helix continuously monitors your application. If production goes down, it automatically:
- Detects the incident
- Clones the project
- Reproduces the failure inside its sandbox
- Identifies the root cause
- Fixes the issue
- Redeploys the application
With over 90+ engineering tools in its disposal, plus vision ability
All while you're asleep.
We're opening Helix to a small group of developers for early testing.
If you'd like to stress-test it on real projects and help shape the future of autonomous cloud engineering, reply below or send me a DM.

Most backend engineers are used to thinking that their job ends once they provide the API endpoints.
But the real question is how well do those endpoints perform when a large number of users hit them repeatedly at the same time? And more importantly, how do you test that during the development phase?
In the video above, I explain how engineers can properly test whether their endpoints can handle scale and repeated requests from multiple users simultaneously, using a tool called Apache JMeter.
The video walks through everything—from installation to running the tool and finally testing your API. For this demo, I used a local service running on my laptop.
Do well to watch, like, retweet, and bookmark so others can learn from it too.

Hey devs! Every time I deployed an MVP on Railway or Render free trials, sending emails with Nodemailer, smtplib, net/smtp, etc. failed because outbound SMTP ports (25, 465, 587) are strictly blocked. Plus, services like Resend force you to buy and setup a custom domain first.
So I built SendLib, a dedicated, production-ready email API for devs.
SendLib lets you connect a Gmail account (e.g. [email protected]) via Google OAuth 2.0 and gives you a secure REST API to send transactional emails (welcome emails, password resets, OTPs) from wherever your product is hosted, straight to your user's inbox.
How it works:
1. Connect your product Gmail account via 1-click Google OAuth.
2. Grab an API key from your dashboard.
3. Send a single HTTP POST request from any language.
Free tier: Connect up to 10 Gmail accounts & send up to 500 emails/day per account (2,000/day for Workspace).

I'd love your feedback! Thank you! 🙏
