Custom software service announcement for Istanbul — hybrid delivery from Samsun

Custom software service announcement for Istanbul

Aksiyon Soft publishes a custom software service announcement for Istanbul fintech operations teams, high-volume e-commerce companies, and agency-born product squads. This item is distinct from generic enterprise portal guides — it focuses on payment services, marketplace integrations, and campaign traffic patterns. Our only HQ is in Samsun; we have no branch or sales office in Istanbul.

The Bosphorus corridor expects fast decisions and frequent releases. Samsun-based engineering and Istanbul product owners or compliance teams share one sprint calendar. Regulatory, KVKK, and financial audit-trail expectations are captured in writing during discovery — not during launch week.

Samsun HQ, hybrid with Istanbul — no branch claim

Architecture, code review, and sprint planning stay in Samsun. We schedule discovery workshops, design reviews, and go-live support days with teams in Levent, Maslak, Kadıköy, or elsewhere. We do not say “we have a local Istanbul office”; use our contact page for official requests.

VPN, SSO, and data residency (KVKK, finance rules) are settled before go-live. Even when teams are distributed, you still need one backlog, one demo day, and written acceptance criteria.

Who in Istanbul? Fintech and e-commerce hybrid

Fintech teams want consoles for transaction monitoring, manual intervention queues, partner bank APIs, and regulatory reporting — often with role separation, four-eyes approval, and immutable audit logs. E-commerce squads tie catalogues, pricing rule engines, stock sync, and returns in one integration layer; peak events like Black Friday are assumptions in discovery, not surprises in production.

Agency-to-product transitions bring technical debt, multi-tenant concerns, and release discipline. Holdings need staging and feature flags that respect group IT policy during phased rollouts.

What the coverage includes in Istanbul

The announcement covers the full delivery cycle for organisations in Istanbul, from the first discovery session to post-launch support:

• Discovery and scope: remote workshops, a process inventory and a written MVP boundary.
• Custom and enterprise software: web portals, approval workflows and order–stock–accounts modules.
• Mobile apps: iOS and Android apps for field and shop-floor teams, with offline support.
• API integration: connections to ERP, accounting, e-invoice and e-waybill systems.
• Maintenance and support: monitoring, security patches and defined SLA response times.

Every engagement starts small and grows in phases, so teams in Istanbul see working software within the first sprints.

Middleware and integration service in Istanbul

For high-volume e-commerce companies and fintech operations teams in Istanbul, the integration layer decides whether the platform stays up on campaign day. Marketplace APIs, carrier webhooks, partner bank services, ERP and e-invoicing are all under load at the same time. Middleware pulls these connections out of application code and into a layer with clear contracts that scales and can be monitored.

On Istanbul projects the layer covers: catalogue, price and stock sync between marketplaces and your own store (with rate limiting that respects API quotas); return and shipping status messages linked to the order record; high-volume invoice flows between ERP and e-invoice / private integrator services; and pick and delivery records from warehouse and field mobile apps. On the fintech side, partner bank APIs and reconciliation files — and, in customer service, AI agents that answer order status questions — connect to the same layer with four-eyes approval and an immutable audit log. In the invoice flow, the latest UBL-TR update should be tested separately.

When frequent releases meet high traffic, these four rules in the layer are non-negotiable:

• Queues and back-pressure: during Black Friday-style peaks messages are queued so target APIs are not overloaded.
• Retries: on rate-limit or transient errors, sending is retried with staged back-off.
• Idempotency: the same payment, return or invoice message arriving twice still results in one transaction.
• Monitoring: latency, error rate and pending messages are tracked with dashboards and alerts.

For your current e-invoice integration we offer an e-invoice UBL-TR integration check service. For agency-born product teams, integration contracts (API schemas) are versioned in the layer, so connections do not break even when front end and back end move at different speeds. Engineering runs remotely from our Samsun HQ, with planned visits to your Istanbul team for design reviews and go-live support days. Architecture details are in enterprise integration middleware architecture, and the scope on our API and integration page.

FAQ

Do you have an office in Istanbul?

No. HQ is in Samsun only; there is no Istanbul branch or sales office. Planned in-person sprint reviews are possible.

Can fintech projects meet face-to-face?

Yes — discovery, security reviews, and go-live weeks can include planned sessions in Istanbul. Day-to-day development continues remotely from our Samsun-based team.

How long does a first project take?

A typical MVP goes live six to ten weeks after discovery, depending on the number of integrations and user roles; later phases follow as separate milestones.
