Description

Hello. I have a legacy web application running in a Digital Ocean droplet, using a combination of PHP and Java. It's been running since 2001, so it's got a lot of old versions of code. I'm getting Status 500 errors after updating some of the jsp files. I'm looking for someone to help me troubleshoot these issues and get a basic java email service running. Familiarity with tomcat and working with older java packages would be helpful. Must be US-based due to the end-customer requirements, sorry.

The Task (Let’s Start Here) We want to promote our site without getting banned. Simple to say — hard to do. So far, we’ve been flagged for: - Account activity (even with proxies) - Comment removals - Posts that feel “too promotional” You need to have: - A Reddit-safe method that works now - A way to show examples (active profiles or results) - A strategy that looks like genuine contribution, not spam This is a not a paid trial— help us promote one thing using your current system. If it works, we’ll grow it together. Who You Are (Ideally) - You’ve promoted AI, NSFW, crypto, or other “flag-prone” content without bans - You understand subreddit culture - You know when to post, when to comment, and when to say nothing - You’ve run multiple accounts safely (and can prove it) - Bonus: You’re open to evolving into broader SEO/link-building roles How to Apply Send a short proposal telling us: - How you currently promote on Reddit - How you avoid getting flagged - Whether you can show an active Reddit profile you manage - What you'd do as a starter campaign for something like “AI girlfriend tools” If it looks good, we’ll send a short form and get moving. What’s In It For You - Real traffic niche with Reddit reach - Long-term work possible if it clicks - Remote, async, and zero micromanagement --- Don’t Apply If You just post the same link in 30 subreddits and hope for the best. We’re past that. You need to know how Reddit really works — and have a live system to prove it. Final Note: This task is a starting point. If your system works, we’re ready to scale with you — across Reddit, link-building, and organic SEO.

Hi Dear There is Google Meet, Zoom , Evmux, , Streamyard --- to conect your social Media Platfomrs ( Eg FB, Youtube, Tik TOk, Linkedin, INstagram) while going LIVE All this is good . But i dont want to have to pay MONTHly or Yearly Subscriptions to use these Platforms So i want someone to creeat me own ( instead of having to go and share my Message /Video to all my other Social Media at a later time . Thus costing me more time ___________________________________________________________________________________________ So I want someone to develop me a Program/APP that is simmply or and smiliar to use like GOOGLE MEET ( as that is the SImpliest of all ) 1) can this app have the ability to BLUR out anything background or Anything you might want to hide /Blur out? 2) Can it have the ability to select at least two or 3 pretty BACKGROUNDS? 3) Can you provide a program/app/ that has realllY HIGH RESOLUTION PICTIURES /Videos? 4) Can you built someone that allows me to connect/integrate my FB, Youtube, Linked in , Instagram, Tik Tok channels to ?? ( So that when i go LIVE. It can go to allow those Platforms similtaneeously? I know with all the AI .There is so much much that can be done easier and faster I could use this . But prefer to hire someone for a affordable price Have you seen this Artificial Intelligence AI for APP Making?? it is called GO.FAMOUS. AI Wait to hear from good ENGLISH SPEAKERS only to BId on the JOb.( was me may need to VERBALLY Communicate for you to demostrate to me how to use it , once it has been Developed, Completed) _____________________________________________________________________________ Second Project I will like done, which of course will mean a SEPARATE PRICE But since i am at it . I have found a lot of VOICECHANGER APPS on Google Play But issue is 1) You have to pay for them 2 ) They sound Echo ., cartoony, and very Hollow What I prefer is something 1) That sounds like a REAL person eg A american Accent 2) Will be free for me to give my friends to use free 3) Something that you can submit to Google Play fr others to have access to free 4) Something that they can just talk right into from their PHone and it is automatically sounding on the other end as a American accent 5) Then I would like it to bave a SHARE capability to it . That that altered Voice note can be shared to Fb or Whatsapp Thanks for making to hearing someone that is VERBALLY speaks english well Again there is AI that is helping APP be created qick and easy.
