GG Tech's Software Engineering practice covers end-to-end development from idea to production across 11 specializations: product strategy, mobile apps, web & SaaS, custom software, MVP development, modernization & migration, performance optimization, IoT/Beacon solutions, software architecture & system design, database engineering & optimization, and system integration & central platforms. Our Istanbul-based team builds scalable systems on modern architectures and secure infrastructure.

Services in this area

Product Strategy & Advisory

Market research, roadmap planning, and technical advisory to build the right product.

Mobile App Development

Native (Swift, Kotlin) or React Native apps for iOS and Android — from the scope conversation to store release, in an 6–16 week planning band.

Web & SaaS Development

Browser-based business applications and subscription SaaS products — tenancy, roles and billing designed up front, in a 10–24 week planning band.

Custom Software Development

A system that runs on your own business rules, for processes packaged software cannot fit — from process analysis to data migration and a go-live without downtime, in a 12–32 week band.

MVP Development

A first release that tests one assumption with real users, with measurement built in from day one — scope cutting, fortnightly releases and launch, in an 6–10 week band.

App Modernization & Migration

Move legacy systems to modern architectures — better performance, lower maintenance.

Performance Optimization

Core Web Vitals, database tuning, and infrastructure improvements for slow apps.

IoT & Beacon Solutions

Indoor navigation, asset tracking, and connected device platforms.

Software Architecture & System Design

.NET backend architecture, the microservice-or-monolith decision, and a domain model that survives growth.

Database Engineering & Optimization

Schema design, index and query tuning on PostgreSQL and MS SQL Server — measured before and after.

System Integration & Central Platforms

Middleware and central systems that feed several applications from a single source of truth, at public-sector scale.

Frequently asked questions

What does your software engineering service cover?

The full software lifecycle, from product strategy to launch and later modernization. We work under eleven sub-services: Product Strategy & Advisory, Mobile App Development, Web & SaaS Development, Custom Software Development, MVP Development, App Modernization & Migration, Performance Optimization, IoT & Beacon Solutions, Software Architecture & System Design, Database Engineering & Optimization, System Integration & Central Platforms.

How long does it take to launch an MVP?

In our estimation model the typical timeline band for MVP development is 6–10 weeks. What drives the timeline most is a clear scope: at the start of the project we write down, together, the assumption the first release must validate and the smallest feature set needed for it. The Cost Drivers page explains how to read the bands.

SaaS or on-premise?

SaaS gives a fast start, low upfront cost and automatic updates; in exchange you accept limits on data location and customization, and a long-term subscription. On-premise gives full control and data locality, with a higher upfront investment and operating load. A hybrid is also possible: the component that needs control (for example, personal data storage) runs on-premise and the rest as SaaS. KVKK (Turkish data protection law) and sector regulation, especially in finance and the public sector, often decide this.

React Native or native for a mobile app?

Native (Swift / Kotlin): camera- and AR-heavy apps, complex animation, OS-specific features or the highest performance. React Native: one codebase for both platforms, fast iteration and reuse of the JavaScript / TypeScript ecosystem (including code shared with the web); it is our choice for cross-platform work. We make the choice with you at the start of the project, based on the requirements.

Which metrics does performance optimization look at?

On the web, Core Web Vitals: LCP under 2.5 seconds, INP under 200 milliseconds, CLS under 0.1. On the backend, p95 response time, database lock contention and cache hit ratio. On the frontend, JavaScript bundle size, critical CSS and lazy loading of off-screen content. Method: take a baseline with Lighthouse and real-user monitoring, make the improvements, then measure again with the same metrics.
