Welzin Open Source Society

Open source built us. We're giving back.

WOSS is Welzin's open source society: plain-English learning, guided first contributions, meetups and talks, and a 30-day residency at our Mohali office where you build beside the team that runs open source in production.

What we run in production

The day job behind the society

The engineers who mentor you run DevOps, MLOps, and AIOps for clients, in production. This is that work.

The 30-day residency · Welzin office, Mohali

Thirty days. Real contributions. Our desks.

Come work from the Welzin office in Mohali for thirty days. You contribute to real open source projects, collaborate with the engineers who run them in production, and work toward merged contributions under your name.

Contribute
Real issues on real projects - your pull requests, reviewed in the open, merged upstream.
Collaborate
Pair with the team on the same DevOps, MLOps, and AIOps work we run for clients.
Belong
Standups, whiteboards, chai runs - a month inside a working engineering culture.
  • Free and selective - we review every application.
  • Rolling admissions - apply anytime; we schedule you when a seat opens.
  • Bring a laptop and curiosity; we provide the desk, the mentors, and the work.

Some residents go home with a merged PR. Some don't leave at all.

The landscape

The map we work from

The foundations WOSS organizes under - Linux Foundation, CNCF, Apache - and the projects we ship code to.
Read the stack top-down, open it as a map, search it, or filter by how deeply we engage.

WOSS's pillars map to the real governance hierarchy, read top-down: the language agents speak, the engine room serving the models, the playbook AI runs by, the retrieval underneath RAG, the guardrails around every repo, the storage floor beside them, and the ground it all runs on - resting on the bedrock that hosts everything. The ASF rail feeds data in from the side. kagent is the keystone: it runs on CNCF, embodies CNAI, and speaks AAIF's MCP.

The language

AAIF

how agents behave and talk

The playbook

CNAI

how AI runs on cloud native (patterns · whitepapers)

The engine room

PyTorch Foundation

the models it serves

The retrieval

OpenSearch Foundation

the context it retrieves

  1. The guardrails

    OpenSSF

    the supply-chain practices wrapping every WOSS repo

  2. The storage floor

    SODA Foundation

    data & storage management - and agent context (Contexture)

  3. The ground

    CNCF

    the infrastructure it runs on (Kubernetes · Prometheus · OpenTelemetry · kagent)

  4. The bedrock

    Linux Foundation

    the neutral home that hosts them all (LFX · certs · events)

Second root

ASF · the data layer

The Apache pipeline that feeds every layer above: streaming ingestion, orchestrated DAGs, distributed feature engineering - the stage before training and inference.

Each Apache project is governed by its own PMC under 'the Apache Way'. Our on-ramp guidance: go deep on ONE project - docs, connectors, or a well-scoped bug.

Field notes

What we're writing

Plain-English writing on Linux, cloud native, and the open source way, from the engineers who run it in production.

All field notes

Write for WOSS

Your first contribution doesn't have to be code

Field notes are written by the community as much as by us. Pitch us a draft - a guide, an explainer, a war story from production - and we'll edit it with you and publish it under your name.

Questions

Asked straight, answered straight

I've never used Linux or git. Is this for me?

Yes - that is exactly who the learn track is for. Step one of the pathway assumes nothing beyond curiosity and a laptop. If you can install an app, you can install a VM, and we take it from there in plain English.

How much time does it take?

A couple of hours a week moves you forward. The pathway is self-paced: some people go install-to-first-PR in a month, others take a season. There are no deadlines and nothing expires.

Is it free?

Yes, entirely. WOSS is how Welzin's engineers give back to the ecosystem their day job stands on. There is no paid tier and nothing to upsell.

Do I need to be in India or in a specific timezone?

No. Everything starts online and asynchronous - the writing, the issues, the reviews. Live sessions and in-person meetups will come as the community grows, and they will always have an async trail.

What does a founding member actually do?

You are early, so you shape it: which sessions we run first, which repos we open, what the meetups look like. Founding members get the field notes and first invites to everything, and their feedback sets the roadmap.

Why does a company run a community?

Because open source built the company. Everything Welzin ships stands on Linux, Kubernetes, and Postgres, and the engineers here grew up contributing. The day job funds the society; the society stays free.

Is the 30-day residency paid? Does it cost anything?

It costs nothing and pays nothing - it is a free, selective residency. You give a month of real contribution; we give the desks, the mentors, and the work. What you leave with is merged PRs and the people who reviewed them.

Where do I stay during the residency?

The residency runs from the Welzin office in Mohali. Travel and stay are yours to arrange - the practical logistics are covered in the reply to your application.

Can I do the residency remotely?

No - the residency is the in-person track, and being in the room is the point. Everything else on this page is the remote path: the field notes, the events, the society itself.
