Senior backup when you're stuck —
part-time power for your team.

I help candidates unblock real job work, and I help companies ship with 3–4 focused hours of senior engineering every day.

Who it's for

Two ways to work with me.

Same senior engineer. Different engagement — personal backup when you're stuck, or part-time capacity for your team.

For candidates

Personal backup

Hourly → monthly

Flexible support

Stuck on the job? Get unblocked.

You're capable — you just need senior backup when the ticket is new, the bug is weird, or the sprint is overloaded. I pair with you on real work so you ship and grow.

  • Feature work & bug fixes on your actual codebase
  • PR reviews before you submit
  • Architecture guidance you can defend in standups
  • Confidential — NDA available

For companies

Team capacity

3–4 hrs / day

Senior capacity

Part-time senior engineer. 3–4 hours a day.

Need production help without a full-time hire? I embed with your team for focused daily blocks — shipping features, owning backlog items, and raising code quality.

  • 3–4 focused hours every working day
  • Feature delivery, integrations & AI agents
  • Code reviews, architecture & mentoring
  • Remote · flexible timezone overlap

Sound familiar?

Real blockers.
Real backup.

Whether you're drowning in tickets or hiring for hours you don't have — this is senior help on the work that matters now.

You're capable. You just need a senior engineer in your corner — for the ticket, the sprint, or 3–4 hours a day on the product.

Candidates · Companies · Confidential

01Candidate
Stuck on the job
I got assigned a feature I've never built before.

How I help

I pair on architecture, implementation, and review — you ship confidently and learn as you go.

02Candidate
Sprint blocked
This bug is blocking my sprint and I'm out of ideas.

How I help

We find the root cause together and fix it without creating more debt for next week.

03Company
Part-time capacity
We need a senior for a few hours a day — not a full-time headcount.

How I help

I join as part-time engineering capacity: backlog ownership, reviews, and delivery you can count on.

04Company
AI delivery
We want AI in the product, but the team is already maxed.

How I help

I build agents and automations from proof of concept to production — then hand them off cleanly.

Same engineer. Two engagement models — personal backup for candidates, daily part-time capacity for companies.

Key projects

Live production work —
not slide decks.

Real products with live URLs. The same production judgment I bring when you're stuck — or when your company needs 3–4 hours of senior engineering a day.

What I help with

Real delivery —
not generic tutoring.

I work on your actual tickets, repos, and deadlines. Everything stays confidential between us.

01

Daily task & feature support

Hands-on work on your tickets — APIs, UI, databases, refactors, and integrations that need to ship this week.

02

Code review & quality

PR reviews, performance checks, security basics, and cleaner patterns your team will actually adopt.

03

Architecture guidance

Schema decisions, service boundaries, and how to explain trade-offs clearly to seniors or stakeholders.

04

AI agents & automation

OpenAI, Claude, and Gemini integrations — booking agents, dispatch, RAG, and internal automations that do real work.

05

DevOps & deployment

CI/CD, AWS, Docker, staging environments, and deployment issues that eat evenings.

06

Team mentoring

Pairing that levels up your engineers while delivery keeps moving — knowledge stays with the team.

How it works

Simple to start. Easy to scale.

01

Share the situation

Candidate stuck on a ticket, or company needing part-time capacity — tell me the stack, blocker, and timeline.

02

Pick the model

Hourly unblock for one-offs, monthly backup for candidates, or a 3–4 hour daily block for companies.

03

Work together

Pair on calls, async on Slack, or I take tasks directly — whatever fits your workflow and confidentiality needs.

04

Ship with confidence

You deliver on time. Candidates grow. Companies get senior output without full-time overhead.

Flexible pricing

Pay for what you need.
Scale when you're busy.

Hourly and monthly for candidates. Custom daily part-time for companies that need 3–4 hours of senior engineering every day.
