Software Architect / Tech Lead
I build complex backend systems for payments, commerce and integrations: security-sensitive flows that have to stay correct under retries, failures and concurrency.
From architecture decisions to hands-on delivery.
A reusable payment extension for Adobe Commerce, built to be distributed across merchants.
A working office access-control system in which software decides, from a biometric verification, whether a physical door opens.
Where a client cannot be named, the work is anonymized.
Payment lifecycles inside commerce platforms: authorization and capture, 3-D Secure, fraud screening, tokenization, post-payment operations and two-card checkout flows.
Server-side systems and APIs across several stacks.
Connecting commerce platforms, CRMs, carriers, mobile apps and public-sector systems, where data has to cross system boundaries intact.
