Database Engineering & Optimization
Schema design, index and query tuning on PostgreSQL and MS SQL Server — measured before and after.
or fill in the form
Database optimization is changing the schema, the indexes, and the queries on the evidence of measurement, so that the same hardware answers faster. GG Tech's Database Engineering & Optimization service starts from the slow-query log and wait statistics rather than opinion, designs the schema and indexes, rewrites the expensive queries, and proves the difference under load. We work on PostgreSQL and MS SQL Server.
| Typical team | 1 database engineer + 1 developer |
|---|---|
| Calendar band | 2–8 weeks |
| Phase split | 30% measurement & profiling · 35% schema & indexes · 25% query rewriting · 10% load verification |
What grows the budget
- Data volume
- Concurrent users
- How far the schema may change
- Available maintenance window
Signs of underbudgeting
- Slow-query logging switched off
- No measurement from production
These are GG Tech Teknoloji planning bands, not a quote — we do not publish prices. Every project is different, so the bands are deliberately wide; they assume a senior, focused team and typical scope, and your project is estimated individually.
How do we work?
- 1
Measurement first
Slow-query log, wait statistics, execution plans. Nothing is changed before there is a baseline to compare against.
- 2
Schema and index design
Normalization decisions, partitioning, the indexes that are missing — and the ones that only cost you writes.
- 3
Query rewriting
Expensive queries are rewritten and re-measured one at a time, so every change carries its own before/after number.
- 4
Verification under load
The gain is confirmed at production data volume and concurrency, not on an empty test database.

Software EngineeringProduct Strategy & Advisory
Market research, roadmap planning, and technical advisory to build the right product.
Mobile App Development
Native (Swift, Kotlin) or Flutter apps for iOS and Android — from the scope conversation to store release, in an 8–20 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 8–12 week band.
App Modernization & Migration
Move legacy systems to modern architectures — better performance, lower maintenance.
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.
System Integration & Central Platforms
Middleware and central systems that feed several applications from a single source of truth, at public-sector scale.
