Products and systems we have delivered
Seven systems, across sports betting, real estate, retail merchandising, telecommunications, and speech and document processing. Different industries, similar problems: data from many sources, high load, and systems that have to keep running. One of them is our own product, which we run in production.
-
Receipt OCR service
A paid API that reads photos of receipts and returns structured data: the total, the receipt number and the other fields a client needs. Every result carries a confidence score, and low-confidence reads are retried on a stronger model before the client sees them. The service spreads its load across several regions, caches repeated prompt content and tunes image resolution to keep the cost per receipt low. We run it in production, so monitoring, model upgrades and cost control are on us.
-
Trading back office for a sportsbook
We designed and built the system around one canonical model of sports, competitions, matches and markets, with fixtures and odds from several providers. Traders create each match once, choose which source supplies each market, and reuse market settings such as minimum and maximum stakes across a whole competition or league. The design covers pre-match and in-play (live) markets from the first release.
-
Virtual sports feed relay
The service polls a provider's XML feeds, works out what changed, and sends only those changes (deltas) to client systems as webhooks. Polling and change detection happen in one place, so client systems never have to poll the provider themselves.
-
End-to-end real estate platform
A platform that takes listing data from several multiple listing services, brings it into one standard model and serves it to search, matching and agent tools on web and mobile. Each feed arrives in its own format and on its own schedule; the ingestion layer reconciles them, records every change and keeps the search index fresh. The data model follows the real estate industry standard (RESO), so new feeds and partner integrations plug in without rework.
-
Speech-to-text and text-to-speech services
For several private companies we built services that turn speech into text and text into natural-sounding speech, behind one API their own products call. The work covered audio formats and quality, language settings, and integration into the clients' existing applications and workflows.
-
Field reporting app and client portal for retail merchandising
A mobile app for field merchandisers and a web portal for the retailers and brands they serve. In the app, merchandisers see the service criteria for each store visit, scan barcodes for inventory checks, take photos and submit their report before leaving the store. The portal shows those reports to clients as soon as they arrive, with linked photos, cumulative and summary views and a notification when a report is ready for review. One backend serves both, taking uploads from a large field team working in parallel.
-
Signal quality control for a telecom network
A system that collects signal quality measurements from network equipment and field devices, processes them continuously and shows engineers where quality drops below agreed thresholds. Measurements arrive in high volume, so the pipeline aggregates them by area and time window and raises alerts on sustained degradation rather than on single readings.
We leave out client names for confidentiality.
