Software for businesses that outgrew paper and scattered files

I build the software your business runs on.

I am Haithem, a software developer. I build the systems that keep track of your customers, stock, bookings and invoices in one place — and the websites that bring you work. I handle the whole technical side myself, and I explain every step in plain words.

What I build

In plain words first, technical details underneath

Websites & web apps

Marketing sites, product surfaces, and dashboards that load fast and look considered. Built on a modern stack with motion, type, and content that earn their place.

In technical terms

Next.js · Astro · ReactHeadless CMS · i18nSEO · Core Web VitalsHosting & CI/CD setup

CRM platforms

Custom customer-relationship systems built around your actual sales motion — pipelines, automations, and reporting that beat the off-the-shelf compromise.

In technical terms

Lead pipelines & deal stagesEmail & WhatsApp automationsRole-based access · audit logIntegrations: Stripe, Slack, Gmail

ERP systems

End-to-end operations software — inventory, accounting, HR, and manufacturing modules that share one source of truth instead of fighting six spreadsheets.

In technical terms

Inventory · Procurement · SalesAccounting · Invoicing · PayrollMulti-warehouse · Multi-currencyReports, KPIs & forecasting

APIs & integrations

Typed, documented backends and the glue between your tools — REST and GraphQL services, webhooks, and third-party integrations that stay reliable under load.

In technical terms

REST & GraphQL APIsAuth · rate limiting · webhooksPayment & messaging integrationsOpenAPI docs & versioning

Performance & SEO audits

A forensic pass over an existing product — find what is slow, what search engines miss, and what to fix first, with a prioritized plan and measurable targets.

In technical terms

Core Web Vitals & profilingBundle & render optimizationTechnical SEO & schemaPrioritized fix roadmap

Maintenance & support

Ongoing care for software that matters — proactive monitoring, dependency upkeep, and a dependable hand for new features and the occasional fire.

Next.jsNestJSReactCMS & Roles

News, activities and branch details lived with whoever happened to type them, volunteer and donation requests arrived as messages, and changing a single line on the site meant waiting for a developer.

One back office, one module each

The team publishes everything itself; no change waits on a developer.

ReactLaravelB2B BookingRole-based Access

Partner agencies checked what was available by phone and message. Confirming one booking and issuing its voucher and invoice could eat a full day of back-and-forth, and the same seat occasionally got sold twice.

Agencies book themselves

From availability check to voucher in a few clicks, with no phone calls.

ShopifyE-commerceLiquidUX

A curated collection from fifteen designer houses with nowhere to sell it: buyers asked for pieces by message, prices were quoted per conversation, and stock lived in a spreadsheet.

A boutique that suits the pieces

The collection sells in four currencies with nobody on the phone.

Next.jsNestJSE-commerceFR + AR (RTL)

Every order arrived as a phone call or a private message, and the delivery price for the buyer’s own commune had to be looked up by hand each time. Nobody could say afterwards what had been shipped where.

The JF LAROSE storefront showing the product range and the cash-on-delivery checkout

A bilingual shop that ships nationwide

Orders arrive priced for the buyer’s own commune, and the courier paperwork prints itself.

TypeScriptCanvas 2DWebRTC Co-opWeb Audio

Browser platformers ship megabytes of sprites and audio before the first frame draws, and online play usually needs a server somebody has to pay for.

Life Quest in its hand-drawn Cuphead art style, mid-fight against one of the four bosses

A game drawn at runtime

Four bosses and online co-op, with zero image or audio files shipped.

The technical side

For dev teams and hiring managers

If this part does not concern you, skip it safely — what matters to you is that the system works and stays maintained. If you are evaluating me for a role or a subcontract, hover a group to light up its tools.

Everyone has the same models, yet one person ships a feature and the other concludes the tool is overhyped. The gap is not technical — it is whether you can write a brief someone else could actually execute.

Most CRMs fail not because of missing features, but because they model someone else’s workflow. Here is how I model the real one first.
