Elasticsearch Jobs

I have an MVP running on Java 17, Spring Boot, REST, and MySQL, and now I need it turned into a production-grade multi-vendor marketplace. The platform must expose dedicated Admin, Seller, and User dashboards, scale confidently on AWS, and remain clean and testable. Scope • Upgrade the existing product, cart, order, and payment modules so multiple sellers can manage their own catalogues independently. • Add advanced search functionality—keywords, categories, price ranges, and vendor filters—backed by Elasticsearch (or a comparable search engine) and integrated with Spring Data. • Introduce user reviews and ratings with a moderation workflow surfaced in the Admin panel. • Deliver real-time notifications for order status updates, stock alerts, and sel...

My MongoDB Atlas cluster connects instantly through Compass, yet the same connection string refuses to cooperate inside my React project. The URI is tucked away in an environment variable, but at runtime I receive a generic “connection string” error and no data appears. I need someone to: • review how I’m importing the .env values and verify the string syntax • confirm the driver / library I’m using from the React side (or its Node-based API layer) is configured correctly for an Atlas URI • diagnose any authentication, whitelisting, or network nuances that Compass might mask • deliver a working example and a brief explanation so I can replicate the fix across environments Once the project builds and fetches data from Atlas without throwi...

Senior Python Developer – Containerized Geospatial Processing Library (Azure) ​Project Overview: We are seeking an experienced Senior Python Developer with deep expertise in geospatial data handling (GIS) and Docker containerization. The objective of this project is to build a robust, standalone Python library and execution environment that performs standardized geoprocessing tasks on vector and raster datasets. ​The final deliverable must be a highly secure, containerized microservice capable of reading from and writing to Azure Blob Storage, with strict input validation. ​Core Tech Stack: ​Language: Python 3.11+ ​Geospatial Libraries: GeoPandas, Rasterio, Shapely, PyProj, Fiona ​Validation: Pydantic ​Cloud: Azure SDK (Blob Storage, Key Vault, Identity) ​Infrastructure: Docker (Alpi...

Our in-house search engine needs a sharp, data-driven eye to make every query deliver the right mix of products, articles, and images. I want you to analyse how users currently interact with results drawn from both textual content and rich imagery, spot the mismatches, then tune the ranking logic until relevance lifts our conversion rate. What you’ll do • Audit the existing pipeline, from query parsing to ranking, on our custom platform. • Work with mixed data (product descriptions, metadata, and image features) to understand which signals matter most for purchase decisions. • Design or refine relevance metrics and an evaluation set we can reuse for ongoing benchmarking. • Implement ranking improvements—whether that means boosting rules in Elasticse...

I maintain several large, structured datasets spread across MySQL, PostgreSQL and SQL Server instances. Only portions of the existing schemas are documented, so the very first step will be to inspect each system, reverse-engineer any missing metadata and confirm table relationships. Once the landscape is clear I need all records extracted, cleaned, normalised and deduplicated, then merged into a single, well-organised MongoDB database. Your work should include a carefully planned document model that supports growth, fast look-ups and straightforward analytics. Proper indexing, sharding strategy (where appropriate) and query optimisation are critical because future workloads will be heavy and latency-sensitive. Please deliver: • An optimised MongoDB schema and architecture diag...

I need two focused Python utilities that help me keep both of my data platforms tidy by flagging objects that haven’t been touched in X days and suggesting safe-to-drop SQL. Program #1 – AWS Athena • Connect to my Athena catalog (I work from the AWS Management Console, but in code I’d like you to stay with boto3). • For every table and view in a specified database, look back over completed query executions for the chosen time window. • Views can nest CTEs or reference other views, so the script must walk the full dependency chain to decide whether a reference is direct or indirect. • Return one CSV with the following columns exactly: database , objectname, objecttype, last_reference_datetime, referencetype (direct/indirect) , referencedBy,...

Saya sedang menyusun rencana produk digital namun masih menimbang apakah ia sebaiknya dikembangkan sebagai situs web, aplikasi mobile, atau sistem backend mandiri. Yang paling saya butuhkan saat ini adalah masukan fungsionalitas—khususnya bagaimana menghadirkan fitur pencarian yang cepat, akurat, dan mudah dipelihara. Ruang lingkup yang saya harapkan: • Analisis kebutuhan bisnis dan teknis untuk fitur pencarian. • Rekomendasi arsitektur (misalnya Elasticsearch, Algolia, atau solusi built-in database) beserta pro-kontra dan perkiraan biaya operasional. • Sketsa alur kerja pencarian (indexing, ranking, filtering) yang sesuai dengan skala pengguna kami. • Saran integrasi antarmuka—baik untuk web, mobile, maupun layanan API—agar pengalaman pengguna ...

I need a freelancer to design, build, and launch an AI-driven, web-based platform that empowers pro se litigants to draft their own court paperwork—from initial pleadings through motions and full legal briefs—without ever cutting corners on authority or formatting. Core goal The heart of the product is intelligent drafting: the system should ask the user plain-language questions, pull only verifiable, publicly available law, and then assemble a finished document that includes pinpoint citations to real cases, statutes, and court rules. Citations must be traceable to the original source and be formatted in Bluebook style (or the local court’s preferred variant) automatically. Jurisdictional coverage Because users often file in more than one venue, the platform must r...
