~/umairjibran · open to new roles
I build backend systems, LLM pipelines, and the integrations between them.
Peshawar, Pakistan (UTC+5) · Europe / North America / Remote
Backend, DevOps, and AI/ML at PuppyDog.io. I built a mass personalization engine scaling from 10 to 10,000+ prospects per job, led a hybrid AWS→GCP migration that cut infrastructure cost by 36%, and lifted backend test coverage from 0 to ~75% — shifting releases from every two weeks to daily. I design around Node.js, Python, AWS, GCP, and agentic LLM workflows, and lean on Datadog for observability. A good chunk of the work is integration work — CRMs like HubSpot, Salesforce and Clay, automation through n8n and webhooks, and the Slack, Google and GitHub APIs. Off the clock you’ll find me hiking

Things I've wired up
Most of what I build has to talk to something else. These are the platforms and protocols I've connected in production — the niche and in-house ones are usually the same job with a different contract.

What people say
I had the privilege of working with Umair Jibran for over two years, and it is without a doubt that he is one of the most talented backend resources I've had the pleasure of collaborating with. Umair not only possesses exceptional technical skills but also carries himself with a remarkable level of professionalism, setting a clear standard for what a Professional Engineer should be.
Waleed Waseem
Co-founder and CEO · Productbox
I highly recommend Umair as an exceptional resource for any project or team. He joined our project with limited experience but quickly proved himself as highly dedicated and a fast learner. He continuously demonstrated a remarkable work ethic, taking ownership for the project tasks and challenges even when they were not his direct responsibility. He constantly strove for excellence.

Jibran is someone who stops at nothing. Once he is challenged to do a task, he delivers the best output no matter what. Being a manager jibran was the easiest engineer to manage. He is always humble and friendly. His learning attitude is amazing and he experiments with the top tech all the time. He is way ahead of his time in his professional journey.

Working together
The questions that usually come up first. Open to new roles: Full-time remote or Relocation (EU / North America).
- Is Umair Jibran available for hire?
- Yes. He is open to full-time remote engineering roles, and open to relocating for the right team in Europe or North America. The quickest route is email or a 30-minute call — both are linked from this page.
- Where is he based, and does remote work actually overlap?
- He works from Peshawar, Pakistan (UTC+5). That is a full working-day overlap with European teams and a solid morning overlap with North America, and he has shipped production work on distributed teams for the last four years.
- What does he actually build?
- Backend systems and the infrastructure under them: Node.js and Python services, event-driven and serverless architectures on AWS and GCP, observability with Datadog, and agentic LLM workflows. At PuppyDog.io he is the sole backend, DevOps, and AI/ML engineer, and also manages two frontend engineers and a QA engineer.
- Which integrations has he shipped?
- CRM and GTM tools including HubSpot, Salesforce, Clay, and SmartLead; automation through n8n and custom webhook workers; Slack bots and slash commands; Google services such as Gmail, Calendar, Drive, and Sheets; GitHub Apps, Actions, and webhooks; plus the plumbing underneath — inbound and outbound webhooks, signature verification, WebSockets, idempotency, and rate-limit backoff. Niche or in-house APIs are usually the same job with a different contract.
- What has he measurably delivered?
- He built a mass personalization engine that scaled from 10 to 10,000+ prospects per job unattended, led a hybrid AWS to GCP migration that cut infrastructure cost by 36%, redesigned a media pipeline down to 11 independent services and roughly 80% lower monthly infra cost, and took backend test coverage from 0 to about 75% — which moved releases from fortnightly to daily.
- How should a recruiter or hiring manager start?
- Email [email protected] or book a slot on the scheduling link. A PDF resume is linked in the site header, deeper write-ups live on the writing site, and the code is on GitHub.
