Hey, I'm Bibin Oommen Mathew. I'm a software engineer and co-founder of Upbrew Technologies building products that care about the product as much as the code.

I like working at the intersection of engineering and product thinking — figuring out what to build, then building it well. Most of my time goes into making software that feels right.

philosophy

I like understanding the problem before jumping into the solution.

I've found that the best work happens when you slow down to ask the right questions first. Who's this for? What does success look like? I try to think about users early and often. it usually saves a lot of rework later.

I lean towards simplicity, shipping early, and iterating based on what I learn. Nothing fancy, just trying to make useful things.

experience

Upbrew

2020 — Present

Co-founder

Co-founded a software studio embedded with client teams from problem definition through ship — working alongside founders and operators to shape products, iterate on real feedback, and deploy software that gets used. Also build and ship in-house consumer apps under the same studio.

Qubryx

2020 — Present

Software Engineer

Forward-deployed engineer on production allocation software for the oil & gas industry. Worked alongside client stakeholders constantly — ideating, scoping, and shipping features against a complex domain, large datasets, and reliability requirements that don't tolerate guesswork.

working with teams

Claude Code consulting for organizations.

I help engineering teams adopt Claude Code as a real part of how they ship — not a sidekick, an operating layer. Custom skills, hooks, MCP servers, sub-agents, and slash commands wired to your codebase, tools, and review process.

Custom skills — Domain knowledge and reusable workflows codified for your team's actual stack and conventions.
Hooks and guardrails — Deterministic checks — tests, linters, secret scans, conventions — that run every time, with no exceptions.
MCP integrations — Linear, GitHub, Notion, internal APIs, databases, monitoring — so Claude can do real work, not just talk about it.
Sub-agents and CI automation — Specialized agents for review, deployment, on-call — plus non-interactive workflows wired into your CI pipeline.
Team playbook — Onboarding, conventions, and a written guide so the team owns the setup after the engagement ends.
