Hire Sybase and Informix embedded-SQL developers
C programs built on Sybase Open Client or Informix ESQL/C are among the hardest legacy code to staff. We find developers who have maintained them for years.
- UK contract with Dreams Technologies Hub Private Limited (VAT registered)
- Engineers delivered from our own Coimbatore office, India
- Shortlist within 5 working days
- Building software since 2013
Where this work comes from
Sybase ASE (now SAP ASE) and Informix were common choices for high-throughput Unix systems. Code that talks to them through C libraries is still in production in:
- Capital markets: trading, settlement and reference data.
- Logistics and distribution systems.
- Telecom and utility back-office systems.
- Older ERP and manufacturing systems.
What our developers do
- Maintain C code using CT-Lib, DB-Lib or Informix ESQL/C.
- Fix connection handling, error processing and performance problems.
- Upgrade client libraries and rebuild on newer platforms.
- Document data access and plan database migrations to Oracle, PostgreSQL or SQL Server.
Profiles we supply
| Profile | Experience | Typical work |
|---|---|---|
| Sybase Open Client developer | 6+ years | CT-Lib and DB-Lib code, stored procedures |
| Informix ESQL/C developer | 6+ years | ESQL/C, Informix 4GL, IDS |
| Database migration engineer | 8+ years | Schema and data-access conversion planning |
What we test in the technical interview
Every candidate is interviewed by one of our own senior engineers. We test the exact things your system depends on:
- CT-Lib or DB-Lib connection, command and result handling.
- Transact-SQL and stored procedures on ASE.
- Informix ESQL/C host variables, cursors and error handling.
- Informix 4GL, where used.
- Build and link settings for the client libraries on your platform.
Three ways to work with us
Dedicated specialist
A named engineer joins your team on a monthly time-and-materials basis. Best when you have live systems, an urgent gap and your own technical lead.
See support podsFixed-scope assessment
Two to three weeks, fixed fee. We map the code, the platform and the people risk, then give you options with effort ranges. Best when nobody fully understands the system any more.
See the assessmentMigration project
Fixed price once the assessment is done. We port, test, run in parallel and cut over. Best when you have decided to leave the platform.

Why teams come to us for scarce skills
Finding thin talent pools is our core skill
Large service firms rarely staff a single Pro*C or HP-UX role quickly. We keep a vetted network of engineers who have these skills and want this work.
Screened by people who have done the work
Our own senior engineers run the technical interview. Candidates are tested on the platform you run, not on general programming.
UK contract, India delivery
You contract with our UK company. The work is delivered from our own office in Coimbatore with working hours that overlap the UK day.
AI-assisted code understanding
Our team works with Claude Code to read, document and test old codebases faster. Every finding is checked by an engineer before it reaches you.
Continuity built in
Every engagement keeps a runbook and code notes from week one, and a second engineer is briefed on your system. Losing one person does not mean losing the knowledge.
We also run the migration
When you are ready to leave the platform, the same team that kept it running plans and delivers the move.
Tell us what you’re running
Send us the stack and the problem. We’ll reply within one working day and, if it’s a staffing request, send a shortlist within five.
FAQ
Frequently asked questions
Can you also help with DB2 embedded SQL in C?
Yes, on request. The screening is similar; tell us your platform and DB2 version.
Should we migrate off Sybase or Informix?
It depends on licence cost, support position and how much C code touches the database. The assessment sets out the options.
