Beijing Yeetech Co., Ltd. · Software engineering
Business-critical systems that have to work in production, not in a demo.
We build and modernise the systems companies actually run on: maintenance-factory workflow, funding and cost control, payroll and branch performance, equipment lifecycle, multi-tenant SaaS and applied AI. 15+ years, named clients, real screens.

What we build
Four delivery shapes, one engineering standard
Custom enterprise software
Line-of-business systems where the business rules are genuinely unusual: maintenance-factory workflow, research funding, payroll and branch performance, equipment lifecycle.
02Platforms & multi-tenant SaaS
A shared platform base — tenancy, RBAC, billing, jobs, observability — turned into vertical products instead of rebuilding infrastructure for every client.
03Hardware + software
Board-level repair and reverse engineering, automated board test, radar-level sensing products with edge-to-cloud software. Software that has to talk to real devices.
04Applied AI engineering
RAG, agents, speech, vision and content pipelines delivered with evaluation, cost control and private deployment — not demos that die after the slide deck.

Client names are used with reference-material status from our 2026 capability brochure. Defence and government engagements are described by capability only.
Selected work
Systems people use every day
How we deliver
Six steps, written down before anyone writes code
Discovery
Business interviews, scope boundaries, decision criteria. Output: requirement list and a written scope you can argue with.
Analysis & review
PRD, use cases, prototypes, review closeout. Output: agreed PRD and prototype.
Architecture
System design, data model, interfaces, integration plan. Output: design doc and database schema.
Build
Module-level iteration with a daily build. Output: runnable increments, not status reports.
Quality
Functional, performance, compatibility and regression testing. Output: test report and closed defect list.
Launch & handover
Deployment, training, trial run, operations handover. Output: runbook, source code, documentation.
Overseas delivery
We have been the offshore team before
For Epico we took over testing and defect fixing in the first three months, then progressively absorbed module development — defect counts and critical defects both trended down. For Advanced Health & Care (UK) we moved Adastra from desktop to web and built the reporting layer that aggregates to county and national level.
“We are very happy to work together with Yeetech's team, and we get really good ROI in the software outsourcing service!”
