Hey, it’s been a while since my last update. I’ve been focused on a few projects behind the scenes, but I’m back with a major Weave milestone.
Weave helps professionals exchange time and expertise using Skill Hours instead of money.
My last update covered the invite application system. Since then, I’ve built:
Authentication: Secure account access with Firebase.
Onboarding: Guided profile and skill setup.
Profiles and portfolios: A place to showcase work, skills, and trust.
Member dashboard: A clear view of activity and ongoing work.
Admin dashboard: Tools for managing users and community health.
Skill Hour Ledger: Tracks every hour earned, spent, or transferred.
Marketplace: Members can publish requests and find collaborators.
Cloud infrastructure: Neon for data and storage, prepared for Cloudflare Workers.
Today’s milestone is the Exchange Workflow, the system connecting everything.
Members can now move from an accepted application into a dedicated workspace, communicate, share files, track milestones, submit deliverables, complete the exchange, transfer Skill Hours, and leave reviews.
The core Weave experience is finally taking shape, and I’m excited to share what comes next.

The milestone view makes the workflow feel tangible—especially the clear split between deliverables and activity. Nice product thinking in how you surface progress without adding noise.
I've contributed as a lead engineer to a multi-tenant HR SaaS platform, owning major backend architecture and full-stack feature delivery.
I designed and built a workflow and approval engine supporting parallel execution, quorum-based approvals, delegation, SLA-based escalation, decision tables, and sub-workflows. I also built its visual workflow designer, template/document generation, forms, search, authorization, integrations, and observability capabilities.
The platform uses TypeScript, Cloudflare Workers, Hono, PostgreSQL, Drizzle ORM, React, TanStack, Cerbos, and OpenTelemetry.
"Zahid has successfully delivered and deployed HCM within our company."
That's from the client review that landed on my profile this week, for OneHub — the payroll and people-operations platform I built for TechFoundry. Monthly payroll with fiscal-year tax withholding, payslips and tax certificates on demand, expense reports read line by line by Claude, and one reporting layer so the dashboard, the payslip and the certificate always agree.
The word I care about in that review is "deployed". Delivered means the code works. Deployed means payroll runs on it every month, people are paid the right amount, and nobody has to call me.
The thing I'd do differently: the tax rules started out hard-coded. Fine for one country, one fiscal year — until it wasn't. We later pulled them out into a rules engine so the same payroll runs across countries without touching the code. Next time that's day one, not a refactor.
It's also a Contra-verified project — the work was paid through Contra, so the review and the case study are tied to the same engagement. Case study: https://contra.com/p/Y3EgrEUc-payroll-and-people-operations-platform
