Selected work led by Vincent Schmalbach, founder of Vroni. The person behind these outcomes is the person you talk to.
Vincent designed and built a production B2B SaaS from scratch: Laravel and Vue, multi-model AI agent workflows across Anthropic, OpenAI, Google, and xAI, hard web scraping with anti-bot handling, team accounts, and subscription billing with Spark and Paddle.
A typo-tolerant search platform across more than 200 million records with sub-50ms responses: MeiliSearch, multi-layer caching, partner APIs, and multi-server operations.
Vincent took over a struggling Laravel 5 / PHP 7.4 platform, upgraded it to Laravel 11 and PHP 8.3+, stabilized the bi-directional Salesforce sync, replaced a failing translation service with an AI-assisted multilingual workflow (DeepL plus Anthropic), and moved hosting to Hetzner with CI/CD.
Refactored the access model of a live healthcare SaaS to explicit memberships and policies, built a second booking-provider integration with OAuth, sync, and webhooks, and kept clinical workflows running while the risky parts got safer.
Added a flexible custom reporting system with configurable columns, exports, and background processing to a large Laravel LMS, and turned customer conversations into technical requirements the team could build on.
Built the workflow layer for instruments, portfolios, triggers, and report templates, connected market-data APIs, and added AI report generation with Stripe billing and background execution.
Migrated a fragmented PHP and Ruby on Rails backend into one Laravel application as a drop-in replacement, cutting monthly hosting from four figures to roughly $150.
Registration, personal day planning, AI-assisted exhibitor matching, QR ticketing with scanning, and admin tools, integrated with an existing WordPress setup.
Took over a hard-to-understand legacy Laravel/Vue configurator with many variants and pricing rules, extended the configuration logic, and improved exports for sales and production without breaking existing behavior.
Full-stack rewrite of an underperforming SaaS in Laravel and Vue, including an AI business-name generator, anti-abuse mechanisms, a multi-step marketing funnel, and high-throughput domain checks.
Automated ingestion and enrichment of car inventory from European dealerships, a consumer marketplace, listing syndication to external marketplaces, and a separate dealer-to-dealer platform.
Instant faceted search over 20,000+ funds and ETFs with Laravel, Vue, and MeiliSearch, plus generated SEO landing pages per fund and Statamic-managed content.
A Laravel platform running scraping, contact discovery, and automated email campaigns across 30+ servers, processing millions of opportunities per month without manual operation.
Data ingestion from large movie and TV databases, AI-generated summaries, and automated scheduling and publishing across multiple blogs.
A bespoke CMS that automates the pipeline from keyword research to publishing, including API connections to freelancer platforms for posting jobs and ingesting finished content.
Cut scripts and reworked media loading on a content-heavy travel site, built internal-linking tooling for a large archive, and improved speed and search visibility inside the existing CMS.
A reverse-lookup product with a try-before-you-buy signup flow, low-friction Stripe subscriptions, and self-service plan management.
Took over a decade-old SaaS on an undocumented custom PHP framework, fixed the urgent problems, documented how the system actually works, and set up a Dockerized development environment.
