You will get a Firebird or InterBase database assessment with an API readiness report
Project details
You have a legacy Firebird or InterBase database (any version, 1.5 to 5.0) and you want to connect it to a website, mobile app, dashboard or automation - but nobody wants to touch the old system.
Before anyone writes code, you need to know what is actually possible. That is what this assessment gives you.
I analyze your database read-only and deliver a written report:
• Schema overview: what data is accessible and how it is structured
• Integration plan: which API endpoints make sense for your goals
• Risk assessment: charset issues (WIN1251 and other legacy encodings), locking behavior with your desktop software, backup and performance concerns
• Fixed-price quote for the API build - the assessment fee is credited toward it
Why me: I run a manufacturing company myself, on a Firebird 2.5 ERP from the 2000s. The API layer on top of it has been in production for years, serving orders, statuses and inventory. Delphi-era schemas, dialect 1, stored procedures from 2004 - familiar territory.
Nothing is written to your database. Your ERP keeps running throughout. NDA signed first if you need one.

About Pavel
Firebird & InterBase Expert | Legacy ERP to REST API | Go, Python
Tchernivtsy, Ukraine - 8:59 pm local time
I build secure REST APIs on top of legacy Firebird databases (1.5 - 5.0) without migrations, rewrites, or downtime. Your ERP keeps working; your website, mobile app, dashboards, and automations get live data.
What I deliver:
- Go / Python API services running next to your database (Windows Server is fine)
- Read-only by default, token auth, rate limiting, OpenAPI documentation
- Deployed as a Windows service (NSSM) with secure tunneling (WireGuard / Cloudflare)
- Writes to legacy databases done safely - including the WIN1251/charset pitfalls of Firebird 2.5 that break most modern drivers
- ETL and automation: scheduled SQL extracts to Excel / Google Sheets / email reports
- Firebird health: backup impact analysis, sweep/GC tuning, slow query fixes
Background: I run a manufacturing company myself - on a Firebird 2.5 ERP. The API layer I sell is the one my own business depends on every day. I speak fluent "legacy": Delphi-era schemas, WIN1251 charsets, stored procedures from 2004, pessimistic locks from desktop CRMs - none of it scares me.
Typical project: assessment in 3 days, working API in 2-3 weeks, fixed price. Ongoing support available.
Stack: Go, Python, PHP/Laravel, Firebird 1.5-5.0, InterBase, MariaDB, PostgreSQL, Windows Server, Linux, Docker, Cloudflare.
Steps for completing your project
After purchasing the project, send requirements so Pavel can start the project.
Delivery time starts when Pavel receives requirements from you.
Pavel works on your project following the steps below.
Revisions may occur after the delivery date.
You share your database details
Version, rough table count, and what you want to connect. Plus either a backup copy of the database or a short screen-share session. NDA signed first if you need one.
I analyze the database read-only
Schema, relationships and which tables map to the endpoints you need, plus charset, locking and backup risks specific to your setup. Nothing is written to your database and your ERP keeps running.
