Project Opportunity Increase

I’m a software engineer working primarily on backend-focused remote projects and distributed systems. Recently, I’ve experienced a noticeable decline in incoming project opportunities, which has made it difficult to maintain a stable and balanced workload. Rather than addressing this reactively, I’m looking to take a more structured approach. I am currently seeking a consultant (or advisor) with experience in software services, agency growth, or technical freelancing ecosystems who can help me analyze the situation and improve my project acquisition strategy. Specifically, I’m looking for guidance on: Improving and stabilizing a consistent pipeline of backend development work Positioning myself more effectively in the remote consulting market Identifying better channels for high-quality project acquisition Long-term strategy for maintaining a balanced and sustainable workload If you have relevant experience or can point me toward someone who does, I would appreciate connecting.

802.1x WiFi Setup for Schools

We need a network engineer to set up 802.1x WiFi across three school sites. Users utilize Entra ID and M365, and there are Netgear APs with no servers onsite, just firewalls and switches. The ideal candidate will have experience in network administration and be able to work with Entra and M365. I use Netgear Insights to manage the hotspots across all 3 sites. I can remote to each site via a PC on each site via Teamviewer. At moment I've set up WIFI ID and PW. However, the government say that this is not good enough and the wifi needs to use 8021x and be certification based. I've looked at using Cloud based authentication but there's a monthly cost, I want someone to provide me a solution where it's all internal, the devices are shared, so they must authenticate to the wifi and I don't want to subscribe to anything, just set up internally. Don't mind if a server is needed, I am phsyically close by to all 3 sites. London / Surrey UK based schools, please provide me with a fixed price for whole project. Devices are Win11 laptops and iPads. All devices are on Intune. Any other questions, please do not hesitate to ask...

Project Manager

Who We Are We are a newly established, fast growing software startup with a strong focus on AI powered solutions.

We are lean, move quickly, and every team member shapes our direction. The Role We are seeking a Project Manager to take full ownership of client relationships, project execution, and developer oversight. Because our work involves AI integrated software, you do not need to be an AI engineer, but you must be comfortable managing projects where requirements can evolve as models are tested and refined. You will be the single point of accountability for on time, on scope delivery, and for keeping clients confident throughout. You must be available during U.S. Eastern Standard Time (EST) business hours. Exceptional English communication skills are non negotiable. You will lead client calls, manage expectations, and navigate ambiguity with clarity and poise. What You Will Do Client Relations (High Priority) Act as the primary, trusted point of contact for all clients. Lead discovery sessions, status meetings, and requirement gathering calls, especially for AI features where behavior may be probabilistic rather than deterministic. Translate client needs into clear, actionable specifications for developers. Manage scope changes, expectations, and tough conversations around budget, timeline, and trade offs. Developer and Project Oversight Supervise and support the developers assigned to your projects, including those working on AI model integration and backend or frontend systems. Prioritize the backlog, assign tasks, and ensure developers have what they need to succeed. Track sprint progress, remove blockers, and maintain delivery momentum. Ensure code reviews, testing, model evaluation, and deployments happen on schedule. Operational Management Set up and maintain project tracking tools such as Slack, Jira, or ClickUp. Create and maintain project roadmaps, timelines, and documentation. Proactively identify risks, particularly around AI performance, data dependencies, or API limits, and communicate them to leadership and clients.

Ability to say no professionally, push back on scope creep, and manage competing priorities. Self sufficiency. You do not wait for instructions; you create structure where none exists. Comfort with AI related uncertainty. You understand that AI features may require iteration, testing, and managing client expectations differently than deterministic logic. Nice to Have (Not Required) Experience working on projects involving LLMs such as OpenAI or Anthropic, open source models, vector databases, or AI evaluation pipelines. Experience working in a fast growing startup, especially under two years old. Basic technical familiarity. No coding required, but comfort with APIs, JSON, or prompts helps. Experience with contract statements of work or change orders. How to Apply Your application must include all three of the following: Your resume A cover letter of three to four paragraphs explaining: Your experience managing both clients and developers. A specific example of a project you saved from going off the rails. Confirmation that you can work U.S. EST hours. A Loom video of approximately five minutes in length. No exceptions. In the video, walk us through your career background and relevant experience. Highlight specific project management wins, how you handle client communication, your approach to leading developers, and any exposure to AI projects if applicable. Speak as if you are in a client meeting: clear, confident, and professional. We are growing fast.
