Hire a Dedicated SQL / Database Developer
The database layer is where most application performance problems originate and where most data integrity issues are created. Our dedicated SQL and database developers design and build the data layer correctly from the start — normalised schemas, efficient indexing strategies, well-structured stored procedures, and views that simplify application queries without hiding performance problems. They work across all major relational databases (PostgreSQL, MySQL, SQL Server, Oracle) and are equally capable of writing the complex reporting queries your BI tools need and the high-throughput transactional queries your APIs depend on. For existing systems, they audit slow queries, rewrite inefficient joins, redesign missing indexes, and turn 30-second reports into sub-second responses. They are the people you call when the database is the bottleneck and you need someone who understands why.

Common questions
Everything you need to know before hiring a dedicated SQL / Database Developer.
You hire a specific person — not a rotating pool. We match you with a vetted professional based on your stack, domain, and working style, you conduct a technical interview before committing, and the person is assigned exclusively to your project for the duration of the engagement. They work within your timezone overlap window, join your team's communication tools (Slack, Teams), and participate in your sprint ceremonies. We handle HR, payroll, equipment, and benefits on our side. You direct the work.
Yes — always. We present 1–2 matched candidates with their CV, portfolio, and a summary of why we think they fit your requirements. You interview them before any engagement begins. If the first candidates are not right, we keep searching at no extra cost until you find someone you want to work with.
Pakistan Standard Time (PKT) is UTC+5. This creates a 3–5 hour overlap with UK/EU mornings, a 4–6 hour overlap with Middle East business hours, and an async-friendly relationship with US/Canada (with a 2–4 hour overlap possible with early starts). We set timezone expectations upfront and ensure a minimum 3-hour synchronous overlap per day with your team.
Within the first 30 days, if the placement is not working — for any reason — we replace them at no extra cost. After the first 30 days, we require 2 weeks notice to transition to a replacement so there is no knowledge gap. Replacement sourcing is included in your engagement at no additional charge.
