Marcin Oleksiak - PHP & Laravel developer with 7+ years of experience, specialising in OctoberCMS. From applicant-tracking integrations at Sainsbury's scale to enterprise software behind Novartis' Single Sign-On - all delivered under ISO/IEC 27001-certified processes.
Recruitment is where marketing sites meet serious software: applicant-tracking integrations, accessibility at scale, and traffic spikes every time a hiring campaign goes live. Here's a selection of what I've built.
One of the UK's largest private employers runs its hiring through sainsburys.jobs - and a separate internal equivalent for existing colleagues. I worked across both: applicant-tracking-system integration, role search, and the content platform recruiters manage day-to-day, built to stay fast and accessible under heavy national hiring campaigns.
Visit sainsburys.jobsFair hiring needs consistent scoring. I built a Laravel application that lets recruitment managers choose which interview questions a role requires and generates unified, editable PDF scoring-criteria documents from that selection - so every candidate for a role is assessed against the same standard, and every interview leaves an auditable record.
I built Yodel's driver recruitment platform - then the company was acquired by InPost. The site was carried through a full corporate rebrand on a live recruitment pipeline: new brand, new domain, preserved applications and integrations, with hiring running throughout. It now recruits at drivers.inpost.co.uk.

Starting from brakescareers.uk, the platform was extended across Sysco's European operations - multiple languages, localised content and per-market recruitment flows served from a shared, maintainable OctoberCMS codebase.

When Tropicana was carved out of PepsiCo, all their sites needed to be rebuilt. I helped build the individual brand sites for the newly formed group - a from-scratch setup on a deadline set by a corporate divestiture.
Career site with ATS integration for CCH, delivering role search and application journeys on OctoberCMS.
cch.careersCorporate web platform for DiversiTech - global HVAC manufacturing group - built for multi-region content management.
diversitech.globalInternal inventory management systems: stock tracking, order flows and role-based access - the unglamorous software businesses actually run on, built in Laravel on MySQL.
Reporting pipelines and dashboards turning operational data into decisions - heavy MySQL query work, aggregation and exports feeding management reporting.
OctoberCMS is a content management system built on Laravel - the world's most popular PHP framework. It's a niche, developer-first choice, and that's precisely why enterprises pick it: instead of fighting a page builder, you get a real application framework with a CMS layer clients can actually use.
End-to-end recruitment platforms: role feeds, search, application journeys, and deep applicant-tracking-system integration.
Single Sign-On against corporate identity providers, role-based access, and software designed to live inside enterprise perimeters.
Programmatic generation of editable, standardised documents - like the interview scoring tooling built for Sainsbury's.
Stock, orders, and operational tooling - line-of-business Laravel applications with role-based workflows.
MySQL-heavy aggregation, reporting pipelines and dashboards that turn raw operational data into answers.
Custom plugins, themes, and upgrades - years of production OctoberCMS across some of the UK's most visited career sites.
All client work shown here was delivered while working at a UK software agency holding ISO/IEC 27001 certification. In practice, that means every project - from Sainsbury's to Novartis - was built inside a certified information security management system, not just with good intentions:
