    I run a finance operation that relies on up-to-the-minute market data. What I need now is a streamlined MIS process that turns those feeds into clear, insightful reports and dashboards. You’ll work with market data exclusively, shaping it end-to-end: extracting with SQL, modelling in Excel for quick ad-hoc views, and visualising in Tableau for daily management reporting. Everything must refresh automatically so my team can focus on decisions, not data wrangling. Deliverables • SQL scripts that pull and aggregate the required market data on a schedule • An Excel model with clean, pivot-ready tables and scenario analysis sheets • Interactive Tableau dashboards (published to our server) featuring drill-downs, KPIs, and one-click PDF exports • A concise hand...

    I have an existing SQL database that needs regular, accurate data entry and ongoing management. The core of the work is keeping every record current, validating each new entry against our existing tables, and running simple queries to confirm that key fields stay consistent over time. You will receive raw data files (mostly CSV) on a scheduled basis. I’ll expect you to import them, reconcile any duplicates, flag inconsistencies, and confirm successful inserts. Familiarity with basic normalization rules, foreign-key constraints, and indexing is important because I want the tables to remain fast and reliable as they grow. Deliverables: • Cleaned, imported data sets fully integrated into the SQL database • A brief log of changes, issues found, and resolutions for each ba...

    Our in-house document management platform has been running smoothly on a C#/.NET stack, MS SQL Server, and AWS for several years, but the developer who built and nurtured it is leaving. I need someone who can step in right away, understand the codebase, and keep the application stable and performant. The immediate focus is routine maintenance—diagnosing and fixing any bugs that surface and squeezing better performance out of the code, database, and AWS resources. I don’t have a current list of issues, yet I suspect the usual mix of edge-case errors and slow queries will emerge once you start profiling the system. You’ll get full access to the Git repository, SQL scripts, and our AWS environment (EC2, RDS, S3). A thorough walkthrough with the departing developer can be a...

    I have a production oracle instance that has grown beyond 100 GB and it now needs to live on SQL ,Server postgres sql . The task covers everything from preparing the source, mapping the schema, transferring the data, and validating that every object—tables, views, functions, and constraints—behaves exactly the same once it lands in SQL Server. Here is what I expect to walk away with: • A fully migrated SQL Server database, ready for cut-over • A repeatable migration script or SSIS/ADF/DMS pipeline so I can re-run the process for future refreshes • A concise migration report highlighting any datatype conversions, performance tweaks, and objects that required special handling • Verification scripts or queries that prove row counts, checksums, and refe...

    Our Oracle E-Business Suite instance and its core databases are straining under heavy loads, and I need an experienced hand to restore peak performance. The assignment centers on performance tuning, specifically: • Query optimisation – analysing execution plans, AWR/ASH reports and SQL traces to cut response times and CPU usage. • Index management – auditing existing structures, redesigning or rebuilding where needed, and advising on partitioning or compression if it brings measurable gain. I will grant full access to the non-production environments first, then schedule controlled moves into production once we agree on the changes. Clear before-and-after metrics are essential; please include a concise report that shows what you changed, why, and the improvemen...

    I run a production MySQL database on a Hostinger VPS and need a reliable partner to keep it healthy month after month. Each cycle you will: • Take full and incremental backups, store them off-server, and verify integrity • Review and tune slow-query logs, indexes, and configuration for peak performance • Apply the latest MySQL and OS security patches, harden permissions, and run vulnerability scans You’ll have root/SSH and phpMyAdmin access, and I expect a short report after each visit summarising what was done, any issues found, and recommended next steps. Everything must be scheduled so there is zero or minimal downtime for my users. If you’re experienced with Hostinger panels, mysqldump, Percona Toolkit, and general Linux server hardening, let’s...

    I’m kicking off a new healthcare patient-management system and the first critical piece is a rock-solid, compliant data layer. The entire scope at this stage revolves around database management—designing, building, and documenting a schema that can safely house patient records, appointments, clinical notes, and billing details while meeting HIPAA-level security expectations. Here’s what I need from you: • Analyse typical patient-care workflows and translate them into an efficient relational model. • Deliver an ER diagram, a fully normalised schema, and an indexing strategy suitable for high-volume queries. • Implement the model in the SQL engine you recommend (PostgreSQL, MySQL, or MS-SQL are all fine if they cover encryption-at-rest, robust backup, a...

    CORE-103 Data & SQL Foundations. 10 topics. Almost every system these students build or support will store its data in a relational database, and almost every serious production incident involves one. From what a database is for through querying, joins and aggregation to schema design, transactions and indexing. Real time goes to reconciliation - checking that a query returned the RIGHT answer rather than a plausible one - because a wrong number delivered confidently is worse than no number at all. Note: this course shares ground with DB-101, the Databases track foundation, at a much shallower depth. You will be asked to coordinate with that trainer so the two reinforce rather than repeat each other. THE 10 TOPICS — FIXED 1. What a database is for (6 h) - persistence, con...

    I have raw sales tables sitting in a SQL-based database and I need them transformed into a clean, interactive dashboard that lets me track monthly revenue growth at a glance. The core KPI is that single figure, but the design should leave room for additional views—regional performance comparisons and top-selling category trends—so the board can evolve without a rebuild. You’re free to use the platform you feel delivers the best user experience; Tableau, Power BI, or even Google Data Studio are all acceptable as long as the final product is fast, visually clear, and can connect directly to my SQL schema. I’ll provide database credentials and an ERD. You’ll handle the data pull, modeling, and visual layout, then publish or package the dashboard so I can share i...
