AI automations that work while you sleep.
I design hands-off workflows with n8n, Make.com, Zapier and Claude — backed by 7+ years of enterprise software engineering, so they keep running when it matters.

Faster incident turnaround, sustained
Track record from 7+ years shipping enterprise cargo-logistics software at CHAMP Cargosystems — the same rigor now applied to your automations.
Services
What I can take off your plate
From no-code speed to full-code depth — pick the entry point, I handle the rest.
Workflow Automation
Connect your apps and eliminate the copy-paste work — leads, invoices, reports and follow-ups that move themselves.
AI Agents & Assistants
Claude-powered agents that read, decide and act — email triage, lead qualification, document processing, support drafts.
AI-Assisted Web Development
Landing pages, portfolios and internal tools shipped fast with Claude + a modern stack. This site is one of them.
API & System Integration
When the connector doesn't exist, I build it — custom REST integrations, webhooks and middleware in TypeScript or Java.
Data Pipelines & Reporting
Scheduled data pulls, cleanups and syncs that land in the right place — with dashboards and digests your team actually reads.
Automation Rescue & Audit
Inherited a fragile Zap or scenario graveyard? I stabilize it — error handling, retries, alerts and documentation included.
Automation Blueprints
Systems I design & build
Sample builds from my automation lab — the exact patterns I tailor to your tools, your data and your edge cases.
Blueprint 01
AI Lead Qualification Engine
Every inbound lead gets scored, researched and answered in minutes — not whenever someone checks the inbox. Claude reads the enquiry, rates intent, drafts a personalized reply, and routes hot leads straight to your phone.
Replaces ~8–10 hrs/week of manual triage · first response in under 2 minutes

Blueprint 02
Invoice & Document Processor
Invoices and receipts land in your inbox; structured data lands in your books. Claude extracts vendors, amounts and line items from any layout, validates the numbers, and files everything with an audit trail.
Zero manual data entry · every document validated and traceable

Blueprint 03
Content Operations Pipeline
One idea in your Notion calendar becomes platform-ready posts for every channel — drafted by Claude in your brand voice, approved by a human in Slack, and published on schedule automatically.
One idea → five platform-ready posts · human approval stays in the loop

Why Me
Hire an engineer, not just a connector.
Anyone can drag nodes onto a canvas. The difference shows up three weeks later — when an API changes, a webhook fails silently, or your data arrives in a shape nobody predicted. I spent 7+ years building and supporting software that airlines depend on around the clock. That's the standard your automations will be held to.
New to freelancing. Not to engineering.
My Upwork profile is new — my standards aren't. Rated “Exceeds Expectations” six review cycles in a row as a software engineer. Early clients get senior-engineer quality at new-freelancer rates.
Enterprise QA discipline
3,100+ production releases shipped at a 99% success rate for global airlines. Your automation gets the same testing rigor.
Error handling by default
Retries, fallbacks and alerting are built in from day one — not bolted on after the first silent 2 a.m. failure.
Custom code when no-code runs out
Most automation freelancers stop where the connector library ends. I keep going — TypeScript, Java, REST APIs, webhooks.
Documentation & true handover
Video walkthroughs, runbooks and clean credentials handling. You own everything I build — no lock-in, ever.
Process
From “this is tedious” to “this runs itself”
Discovery call
Free · 30 minFree 30 minutes. You tell me what eats your team's hours; I tell you honestly what's worth automating — and what isn't.
Blueprint & fixed quote
1–2 daysYou get a visual workflow map, the exact tools involved, and a fixed price. No surprises, no hourly meter running.
Build & test
Staged rolloutI build in stages and test the ugly paths — bad data, API timeouts, edge cases — before anything touches your live accounts.
Launch & monitor
2 weeks includedGo-live with alerting wired up. I watch the first two weeks closely and tune anything that drifts. Included, not extra.
Handover & docs
You own it allVideo walkthrough, written runbook, and full ownership of every account and workflow. You're never locked in.
Toolbox
No-code speed. Full-code depth.
Contact
Let's automate the boring parts.
Tell me what eats your hours — I'll tell you honestly whether it can run itself. Free discovery call, fixed quotes, no lock-in.
This site was designed and built with Claude — a working demo of the AI-assisted workflow I bring to every project.
