Work With Me
Custom development, scoped and delivered
A WordPress plugin, an API integration, a payment fix, an AI feature. Described on Monday, delivered in about a week.
I'm a full-stack developer who ships production software — payment systems for enterprise clients, block-first WordPress, React and Node applications — and who runs two SaaS products of my own. You get one person who writes the code, owns the deploy, and is still around when something breaks.

What I do
Most projects touch more than one of these. That's the point — you don't have to coordinate between a dev shop, a WordPress contractor, an AI consultant, and an SEO agency.
Custom AI integration
LLM features that survive real traffic — support agents, grounded answers over your content, and cost-controlled model routing. Claude, OpenAI, or self-hosted. Running in production on my own SaaS today.
See the AI work →Payment integrations
Stripe billing, Meshulam, custom WooCommerce gateways, and crypto. I built the payment system behind an agency's enterprise clients, and run Stripe billing on my own products.
See the payment work →WordPress plugins & Gutenberg
Plugins and block-first builds written like software, not page-builder bloat. I've shipped 30+ custom React Gutenberg blocks for enterprise clients, a WPML multilingual RTL architecture, and two plugins live on WordPress.org, one of them a WooCommerce payment gateway.
Web applications
Frontend and backend by the same person. React, Next.js, Node, TypeScript, PHP. Real-time features, Chrome extensions, and database migrations done without downtime.
Integrations & automation
Making systems agree with each other, forever, without a human checking: third-party APIs, OAuth, webhooks with retries, CRM syncs, PDF generation, and the reconciliation nobody enjoys.
SEO & organic growth
Technical SEO shipped by the person who diagnosed it — rendering and indexability, keyword architecture, internal link engineering, and page templates you can actually scale.
Why It Matters
Shipping and being found are the same project
The usual split causes real damage. The dev team builds a fast single-page app with one URL, and there's nothing for Google to index. The SEO agency asks for thirty landing pages, and the dev team quotes six weeks because the templating wasn't built for it. Both are right. Neither owns the outcome.
When one person does both, the architecture decisions get made with search in mind from day one — URL structure, rendering strategy, internal linking, page templates you can actually extend. And when a keyword opportunity shows up eight months later, shipping the page takes an afternoon instead of a sprint.
I've done this on my own products, which is the honest reason I can claim it. GhostChat, Gmailytics, and KaspaWoo were built, launched, and grown by one person — product and organic growth both.
Proof
Shipped work, not a capabilities deck
Everything below is live, and most of it you can inspect yourself.
30+ custom Gutenberg blocks — and a generator to make more
At One Digital I built more than thirty React-based Gutenberg blocks for enterprise clients including Dimri, Sonol and Rishumit. Building them one at a time was the bottleneck, so I wrote a metadata-driven ACF block generator that produces the registration, fields and template from a single definition — it cut block development time by roughly 80%. That's the pattern I bring to WordPress work generally: if a task is going to happen fifty times, the second one should be generated, not typed. The same project ran WPML multilingual with Hebrew RTL and English LTR sharing components, which sounds like a CSS flag and turns out to touch layout, forms and every third-party embed.
GhostChat — a SaaS with paying customers
GhostChat is a privacy-first chat widget with a ~15KB embeddable SDK: a Next.js dashboard on Vercel, a Cloudflare Workers API with Durable Objects for per-conversation state, Supabase for persistence and Stripe for billing. It ships with an AI responder running on Claude in production, a plugin on WordPress.org, and an open-source agent runner on npm. Scoped, built, launched and sold by one person. The chat widget on this page is that product.
Gmailytics — OAuth at scale, independently security-audited
Gmailytics is a web app plus Chrome extension that scans a Gmail inbox and bulk unsubscribes from unwanted senders. It has cleaned 5M+ emails and freed over 300GB of storage, and it's Google CASA Tier 2 certified — it passed an independent third-party security assessment for its use of restricted Gmail scopes, a bar most side projects never clear.
Migrations that didn't take the site down
At Hertz Furniture I migrated a CRM of over 100,000 records to Salesforce with zero data loss and zero downtime, then built LiveChat bots and Salesforce webhooks that cut response time from hours to under ten minutes, and integrated Microsoft OneDrive via the Graph API for a 40% storage cost reduction. At Elphi I moved a production application from Firebase to PostgreSQL and added GraphQL subscriptions so the UI updated in real time.
The thread running through all of it: the interesting problems are rarely "build a form." They're "make these four systems agree with each other, forever, without a human checking." That's the work I like most and do best.
Selected Client Work
Built for other people, in production
Alongside my own products, this is work I shipped as a developer at a digital agency and at a US company — for their clients, stated as outcomes rather than tech specs.
Payments for an agency’s enterprise clients (as an employee)
Designed and built an end-to-end payment system on Strapi with the Meshulam SDK: the frontend SDK, lifecycle hooks and webhook reconciliation. It processes over $1M a year, annualized.
Block-first WordPress for agency clients Dimri, Sonol and Rishumit
30+ custom React-based Gutenberg blocks plus an automated ACF block generator that cut build time by 80%, and a WPML multilingual architecture with full RTL/LTR support — delivered for named enterprise clients.
Salesforce migration and workflow automation
Migrated 100K+ records into Salesforce with the REST APIs and automated workflows around it. Integrated Microsoft Graph for OneDrive, cutting storage costs 40%, and implemented SignNow e-signatures that reduced contract turnaround by 90%. Delivered fully remote for a US company over two years.
Looking after WordPress sites, not just building them
Managed and built three sites for an online media organisation: keeping WordPress, Elementor and plugins current, managing DNS, SSL and caching across cPanel and Cloudflare, and running the analytics and Search Console side — sitemaps, conversion tracking, and fixing what the data said was broken. That day-to-day upkeep is what the care plan below is.
In Their Words
What clients have said
“Jacob provided meaningful insight to issues we were experiencing with our site. He is a forward thinker and solution orientated. Very happy he joined our team. Excellent work!”
“Jacob was extremely responsive, flexible and easy to collaborate with. Jake was able to bring our ideas to life without long meetings or constant back and forth. We would rehire Jake in an instant.”
“Jacob is the detail-oriented and time-conscious developer that developed the ROOTS Africa organization website. His creativity and open-mindedness made the process easy and accommodating for us. He listens to the client’s needs and delivers beyond the client’s expectations.”
How We Work Together
Engagement models
Small, well-defined jobs have a fixed price. Larger builds are quoted after a conversation.
Fixed-price build
One clearly scoped piece of work, done in about a week: a WordPress plugin or block-first Gutenberg build, an AI assistant or LLM feature wired to your content, a third-party API or webhook integration, a Stripe or WooCommerce payment fix, a performance rescue, a migration. You describe it, I confirm the scope in writing, half is paid to start and half on delivery. Smaller scoped jobs start at $500; a custom payment gateway starts at $1,200. Larger work is quoted.
Project build
A defined thing, delivered. A plugin, an integration, a marketing site, an MVP. Fixed scope, milestone-based, with a written spec before anyone writes code.
Care plan
Keeping a WordPress site that already works from quietly falling over: updates with a backup first, monitoring, and up to three hours a month of fixes. What's included, what's extra, and how it works are on the WordPress care page.
Ongoing retainer
A developer on your product every week, not just keeping the lights on — shipping new features, building out pages, and iterating on what the analytics and Search Console data say. This is where compounding growth happens.
Audit & rescue
Something is broken, slow, or silently losing you traffic. I diagnose it, document what I find, and either hand you the fix list or implement it.
Process
What working with me looks like
- A real conversation first Thirty minutes on what you're actually trying to achieve. If I'm not the right person, I'll say so — I'd rather tell you in the first call than the third invoice.
- A written scope What gets built, what doesn't, what it costs, and when it lands. No code starts before we both agree on this document.
- Build in visible increments You get a working preview URL early and it updates continuously. No four-week silences ending in a surprise.
- Launch with measurement wired in Analytics, Search Console, and conversion tracking are part of the build, not a follow-up ticket. You can't iterate on what you aren't measuring.
- Iterate over quarters Organic growth is not a launch event. The sites I've grown got there through months of adding pages, fixing what underperformed, and doubling down on what ranked.
Questions
Common questions
Do you work with clients outside Israel?
Yes — most of my work is with US and European clients. I'm a native English speaker (American, University of Maryland), and Israel time zone overlaps a full working morning with Europe and the early afternoon with the US East Coast.
How long until SEO work shows results?
Technical fixes can move rankings in days. Building genuine organic traffic on a new site takes quarters, not weeks — my own sites took months of consistent publishing before traffic became meaningful. Anyone promising you page one in 30 days is selling something else.
Can you take over an existing codebase?
Regularly. A good portion of my professional work has been inheriting half-finished systems and getting them to production — legacy PHP, undocumented WordPress builds, and applications whose original developer is long gone.
Are you available full time or freelance?
Both. I run my own SaaS products and take on select client work alongside them. If you're hiring for a founding or senior engineering role, that conversation is welcome too — my resume is here.
Who owns the code?
You do. Client work ships to your repository, your hosting, your accounts. No proprietary platform lock-in and no hostage situations if you later bring things in-house.
