Sainsbury's: legacy-to-new systems bridge for a FTSE 100 grocer.
Sainsbury's, the FTSE 100 grocery retailer, was caught between three generations of technology: older, inflexible legacy systems, rigid vendor solutions that couldn't be bent to fit, and new systems still being built. Enigmatix engineered the bridging software that made these complex interactions work — the unglamorous connective tissue inside mission-critical retail systems. The brief was explicitly interim: the software needed to last 12 to 18 months while replacements landed. It was still in active production five years after it was written, inside mission-critical systems — a verdict Fraser Pearce, Senior Engineering Manager at Sainsbury's, summarised as software that "stood up well". Interim code that outlives its replacement plan by a factor of three is the quietest kind of engineering proof.

The software Enigmatix Global developers wrote stood up well, long beyond the interim scope of it needing to work for 12 to 18 months, and was still in active use 5 years after its creation, since it was part of mission-critical systems.”

It was engineered to production standard regardless of the 12–18 month brief — clean interfaces to legacy, vendor and new systems meant nothing forced its retirement.
Older legacy platforms, rigid third-party vendor solutions, and new systems under active development — all within the retailer's mission-critical estate.
