Today I'm the technical lead on AgroInsurance, a parametric crop insurance platform that pays out based on soil-moisture triggers and covers all of Kazakhstan. I make the architecture calls, work directly with agronomists and domain experts to translate their rules into something a system can actually compute, and plan the roadmap quarter by quarter. Alongside that I own OrtaBilim, the government subsidy system used by 10,000+ schools, from gathering requirements to what runs in production. The end-of-year disbursement period is unforgiving — if it's down, schools don't get paid — so most of my attention goes to reliability. I also set up structured logging and monitoring across both platforms: we used to find out about problems when someone called, now we see them first. Some of what I've built along the way. I rewrote the geospatial backend from GeoJSON vectors to server-generated raster tiles stored in MinIO with caching, which took maps from unusable to instant — roughly 40–50x faster, handling 10,000+ polygons at once. I designed the data layer for AgroInsurance with PostgreSQL partitioning, Redis and ClickHouse for analytics. I took the soil-moisture processing pipeline from 30 minutes to 5 across 5,000+ sub-districts using async batching, multithreading and partitioning, raising database throughput about 10x. I moved file storage out of PostgreSQL BLOBs into MinIO S3 with SHA-256/MD5 deduplication, encryption in transit and at rest, and command-injection scanning, freeing up terabytes. I built a government budget monitoring system from scratch — architecture, schema, CI/CD — and it holds 150 RPS on a single server with no horizontal scaling. I wrote a multilingual translation microservice with async dispatch, PII detection and response caching that does 7,000 sentences per minute and is now used by 30+ projects. I also standardized CI/CD and deployment across three internal projects, which mostly meant fewer "works on my machine" conversations. One thing I care about separately: working with junior engineers on async patterns, query optimization and code review. That's probably paid off more than any single technical decision.
