AI Knowledge Search / RAG
Transform research papers, specifications, internal documents, CSV files and agricultural datasets into searchable AI knowledge systems with question answering and summarization.
AI, search, agricultural data and field measurement systems
Turning 30 years of engineering knowledge into systems that work.
Hongyan Meng helps organizations build practical systems across information retrieval, semantic search, sensor networks, C/Java/Python development, image recognition, federated learning, Android apps and web-based management platforms.

Positioning
A rare engineer who understands legacy systems and modern AI.
The source materials show a consistent theme: collecting data, structuring it, searching it, and turning it into tools people can use. Experience includes SDD/LSI semantic search, large-scale agricultural information retrieval, sensor networks, business applications, neural networks, YOLO, Flower federated learning, Supabase and Grafana integration.
The strongest business direction is not generic outsourcing. It is specialized AI, search and measurement systems for research, agriculture and field operations.
Services
What I Can Build
Agricultural Data Platforms
Integrate sensors, barcode records, CSV files, images and measurement values into a practical workflow from field input to web management and dashboards.
Image Recognition and Federated Learning
Set up and validate YOLO, COCO datasets, Flower, Docker and virtualized environments for secure machine learning experiments.
Legacy C / Java System Revival
Analyze older C, Java, SWT and Tomcat assets, fix memory and runtime problems, create GUI tools, migrate systems and organize source code for maintenance.
Android and Web Business Apps
Build Bluetooth measurement, local Room storage, synchronization, Supabase authentication, APIs, CSV/JSON export and Grafana visualization.
Technical Research and Documentation
Support requirements definition, detailed specifications, API lists, database design, execution manuals, reports and delivery packages.
Proof
Selected Experience
-
Search Research
Researched and implemented a Japanese agricultural information retrieval system using Semi-Discrete Matrix Decomposition for over 200,000 documents.
-
Agricultural Systems
Developed systems around agricultural information, XML/XSD, JAXB, Java/SWT clients and search server integration.
-
Business Systems
Long-term experience in enterprise software, financial system migration, web systems, server setup, testing and maintenance.
-
AI and Vision
Extended C-based neural network software, created Windows GUI tooling, converted image datasets, and built YOLO and Flower execution environments.
-
Field DX
Defined and developed barcode measurement systems with Android apps, web dashboards, Supabase authentication, InfluxDB/Grafana visualization and CSV/JSON export.
Business
High-value Business Directions
1. AI Search for Research Institutes
A small RAG package for past documents, papers, specifications, CSV files and image metadata, offered with setup and monthly maintenance.
2. Agriculture and Measurement DX
Barcode, Bluetooth measurement, CSV management and dashboards have clear operational value and are suitable for PoC-to-production contracts.
3. Legacy AI / C Repair
Fewer engineers can read older C and Java assets today. Repairing research code, Windows tools, memory problems and migrations can become a premium spot service.
4. AI Environment Setup
Docker, YOLO, Flower, LLM and GPU or virtual environments often block teams. Setup plus documentation is a concrete, short-cycle service.

How This Site Helps Promotion
- Search keywords are focused around AI search, agricultural DX, sensor measurement, legacy C repair and federated learning setup.
- The consultation path is written around practical needs: AI search for research materials, web management for field measurement, and repair of old programs.
- The domain sddsearch.com can be linked from GitHub, X, CrowdWorks, proposals, invoices and delivery reports.
- Future case-study pages can be added while hiding confidential client details.
Consultation
Available for AI, search, measurement and business system development.
