Reporting that stopped feeling slow
Vipani ERP · Akkenam Technologies
Problem. Reporting workflows were running into slow scans, and report screens took 800ms+ to answer.
What I did. Profiled the queries with EXPLAIN ANALYZE, then added composite B-tree indexes in PostgreSQL and compound indexes in MongoDB aggregation pipelines.
Result. Reporting query time dropped about 50%, from ~800ms+ to under 400ms.
An API that answers in half the time
Vipani ERP · Akkenam Technologies
Problem. Everyday ERP calls were taking 450ms+, and peak read traffic landed straight on the database.
What I did. Batched related queries and put Redis caching in front of catalog lookups and sessions.
Result. Response times fell from ~450ms+ to ~225ms, and the database carried less load at peak.
Field commands that fail safe
Irrilot · PPV Technology
Problem. Irrigation commands travel to devices in the field, where a connection can drop at any moment.
What I did. Programs and Groups use handshake acknowledgments and a 120-second watchdog, over MQTT on WebSocket. Pump-trip alerts reach the team through Firebase Cloud Messaging.
Result. 100+ active field nodes respond in under a second, and a program ends safely if the handshake is lost.
One app for two platforms
Irrilot · PPV Technology
Problem. Field teams needed the same monitoring and control app on both Android and iOS.
What I did. Built it once with Ionic React, TypeScript and Capacitor, with reusable components and hooks designed in Figma first.
Result. One codebase ships to both Android and iOS, and new screens reuse the same building blocks.
