Gyld is an independent software engineering studio founded in Athens in 2022. We design, build, and modernise complex products end to end: web, mobile, and SaaS product engineering; platform and backend engineering with Python, Django, and PostgreSQL; data pipelines and AI systems built with human oversight; and compliance-ready software for security- and audit-conscious organisations.
Our Codebase Rescue service gives teams with inherited, fast-built, or AI-assisted codebases a structured technical assessment across architecture, code, data, security, delivery, and operations with an ordered roadmap of what to keep, fix, refactor, or rebuild.
Every engagement has a named technical owner who stays involved from architecture through production. We work with founders and product teams across Europe and the United States that need engineering depth, continuity, and accountable delivery.

Major clients
Processes and approach
How do you gather and validate client requirements?
We start every engagement with structured discovery: working sessions with the people who own the problem, plus a review of any existing code, data, and infrastructure. Requirements are written up as user workflows and constraints, including security and compliance obligations, and validated with the client before build. Where uncertainty is high, we de-risk with prototypes or a standalone technical assessment first. Scope, priorities, and success criteria are agreed in writing, and architecture decisions are recorded so the rationale stays visible throughout the project.
How do you ensure alignment with client goals and business strategy?
Every engagement has a named technical owner who understands the product context and stays involved in decisions from architecture through production. We translate business priorities into a technical roadmap, so sequencing reflects commercial goals, enterprise procurement, a funding milestone, a compliance deadline, not just engineering preference. Architecture decision records tie each significant choice back to its business rationale, and regular reviews measure progress against outcomes the client cares about, not output.
Which software development methodologies do you use (e.g., Agile, Waterfall, Scrum)?
We work iteratively with an agile approach adapted to each client rather than imposing ceremony. Delivery runs in short cycles against a shared roadmap: each cycle ships a usable increment, gets demoed, and feeds back into priorities. For teams with their own process we integrate into their cadence (Scrum or Kanban). For assessments and modernisation work we follow a structured framework covering architecture, code, data, security, delivery, and operations, producing an ordered remediation roadmap.
How do you keep clients and stakeholders updated on project progress?
Clients get a shared channel with the team for day-to-day questions, written progress summaries, and a demo of working software at the end of each delivery cycle. The roadmap and task board are visible to the client throughout, so status is never a surprise. Significant technical decisions are documented in architecture decision records the client can read. When something threatens scope or timeline, we raise it immediately with options, not at the next scheduled meeting.
How frequently do you hold check-in meetings or status updates?
Our default is a weekly status call plus continuous async updates in a shared channel, with demos of working software at the end of each delivery cycle. We adapt the cadence to the engagement: fast-moving builds may warrant twice-weekly check-ins, while a long-running platform partnership may run on fortnightly reviews with monthly roadmap sessions. Urgent issues are raised the day they appear, never held for the next meeting.
What quality assurance practices do you follow?
Every change goes through code review. We maintain automated unit and integration tests run in CI, deploy through staging environments before production, and manually exercise the critical user workflows before each release. Security is treated as part of quality: access control, audit trails, and data handling are reviewed against the client's compliance obligations. For performance-sensitive systems we test under realistic load. Post-release, monitoring and error tracking catch regressions early.
How do you identify and manage project risks?
We surface risk early: discovery and, where warranted, a formal technical assessment identify architectural, data, security, and delivery risks before they become expensive. Unknowns are de-risked with short technical spikes rather than assumptions. During delivery we keep a live risk register, ship incrementally so problems appear small and early, and protect the workflows users already depend on when modernising existing systems. When a risk materialises, the client hears about it immediately, with options and a recommendation.
What kind of support or maintenance do you offer after delivery?
We offer ongoing maintenance and support retainers covering monitoring, incident response, dependency and security updates, and continued feature work. Because the same team stays available, clients keep the context, no repeated discovery or handover. Every delivery includes documentation and a clean handover, so clients are never locked in. Many engagements continue as long-term platform partnerships; others need only periodic health checks. Response expectations and SLAs are agreed per engagement.
