    Office365 Contacts Migration to HubSpot
    6 วัน left
    ยืนยันแล้ว

    I have roughly 8,000 names sitting in Microsoft Office 365 and I’m moving everything into HubSpot CRM. Before the import happens I want the database properly scrubbed: identify and merge duplicates, flag incomplete records, and send a one-time “permission to stay in touch” email to everyone who has an address. Any record that bounces or does not reply will be set aside so I can decide later whether to archive or delete it. Records that have no email at all need to be reviewed manually; when it makes sense, reach out via LinkedIn or other channels to confirm contact details. Once the list is clean, categorise every approved contact so that I can segment future campaigns. Current buckets are: • Clients • Partners • Contacts from past business init...

    I need an Oracle HCM Cloud reporting specialist who can build and fine-tune custom BI Publisher reports and HCM Extracts for the Core HR and Talent Management modules now in production.

    FusionPBX School Bell App & Logo Installation
    4 วัน left
    ยืนยันแล้ว

    I already run FusionPBX and have the full source code for a pre-existing school bell application that is known to work with it. Your task is to install that app on my live server, compile or otherwise build it where necessary, register it inside the FusionPBX menu, and confirm that scheduled bells trigger correctly through FreeSWITCH. Once the bell app is fully functional, replace every instance of the default FusionPBX logo (login page, top-left dashboard, and favicon) with the PNG I will supply, making sure cache issues are cleared so the new branding shows immediately for all users. Deliverables • Bell app installed, visible in the FusionPBX GUI and surviving reboots • Custom logo applied system-wide without layout issues • Short summary of the steps taken (comman...

    SQL Developer & Manual Tester

    I need an experienced hand with Microsoft SQL Server who can both build and scrutinise. On the development side you will design the underlying database for a desktop application, write and fine-tune the T-SQL queries it relies on, and wrap key logic into clear, reusable stored procedures. Once the data layer is in place I want a second set of eyes on the finished product: structured manual testing of the desktop app, covering common user flows as well as edge cases that could expose performance or integrity issues. Precise reproduction steps, screenshots or short clips, and concise bug reports in a tracker of our choice will be expected for anything you uncover. Deliverables • Normalised schema and migration scripts • Optimised queries and documented stored procedures ...

    AI Oracle Performance Monitor
    23 ชั่วโมง left

    I need an AI-driven solution that plugs into my Oracle instance and pinpoints query-level problems in real time while still giving me the option to run scheduled, deeper analyses. The focus is squarely on query performance: I want to see why certain SQL statements are slow, which ones are consuming the most CPU or I/O, and where locking or blocking is stalling throughput. Although memory usage or broader database-wide operations could be future add-ons, right now the win for me is a tool that can learn from AWR/ASH data, parse execution plans, correlate wait events, and surface clear, actionable recommendations—think automatic index advice, rewritten SQL hints, or resource limit alerts. Live dashboards or push notifications are essential for the real-time side, while PDF or HTML r...

    Odoo 19 Speed Optimization

    I run Odoo 19 Enterprise and spend a lot of my day creating new products, assigning attributes, generating variants, then updating prices, stock levels and descriptions. Right now each save spins for far too long; I need that round-trip to finish in about 30 seconds or less. There are several custom modules in the database, so the job starts with profiling: pinpoint whether the slowdown lives in my add-ons, the ORM calls, PostgreSQL queries or server configuration. Once the bottlenecks are clear, I expect code refactoring, proper indexing, possible cron or queue adjustments and any server-level tuning required. Tests should prove that a standard product record – with its attributes and variants – can be created or edited and fully committed within the 30-second window. Delive...
