Services
Banking, Payment and Collection Systems
Many years of experience in core banking applications and corporate credit systems; vehicle loan and financing solutions. Virtual and physical POS integrations, bank connections and collection platforms — highly available systems that run uninterrupted, around the clock.
Experience spanning startup products taken from zero to production and enterprise sales and management systems. Cloud architecture on the AWS ecosystem, CI/CD pipelines and scalable infrastructure; modern web and mobile development with React and React Native. Migrations from off-the-shelf packages to architecture built for the organisation.
From national marketplace integrations to B2B dealer portals: systems that bring sales, ERP, accounting and shipping data under one roof. Reporting that shows the real profit remaining after commissions and cost items, product by product; solutions that gather an SME’s entire marketplace operation onto a single screen.
Assistants that converse with an organisation’s own documents, support automation over WhatsApp, document processing pipelines. Experience in RAG architecture and multi-tenant assistant platform development; with a deployment option that keeps data from leaving the organisation, compliant with GDPR and Turkish KVKK.
Projet SolutionsPayment Infrastructure2024 — ongoing
A collection platform unifying banks and payment providers
More than 30 banks and payment providers, each with its own rules, error structures and security flows, were standardised behind a single coherent architecture. With controls that prevent duplicate payments and an isolation layer that protects the whole during provider outages, the platform can collect at any hour of the day.

SadalDealer Portal2025 — ongoing
Continuity and evolution of a dealer portal
The live e-commerce portal that runs dealers’ daily order operations continues to be developed without downtime. New features, performance improvements and release management are deployed in planned steps, without stopping a working system.
Real profitability per product in marketplace sales
Sales data from national marketplaces is unified with accounting, order and shipping records under one roof. The real profit remaining after commission, shipping and cost items appears product by product on a single screen — pricing and stock decisions are now made with data.
A product built within Solidalab: it lets organisations set up assistants that converse with their own documents and answer over WhatsApp. Thanks to a multi-tenant architecture each organisation configures its own assistant quickly; data can stay resident, without ever leaving the organisation.

Digital transformation built for the organisation
Dedicated software was developed for each of the sales, order and reporting processes; dependence on an off-the-shelf ERP came to an end. With external integrations to insurance and returns systems and a dynamic reporting infrastructure, operations were consolidated onto a single platform.

From idea to product, a startup project
The product of a Delaware-based venture digitalising merger and acquisition (M&A) processes; from architecture to AWS infrastructure, from CI/CD pipelines to payment integration, it was designed in full and taken from zero to production.

DigisecureDigital Forensics Platform2023 — 2024
