1 job
$300+ total earnings

I'm a results-driven Sales Development Representative with over 4 years of hands-on experience in prospecting, cold calling, lead generation, client communication, and appointment setting across the US real estate, renewable energy, and service-based industries. I've worked extensively with dialers such as ReadyMode, MightyCall, and other dialing platforms, as well as CRM systems including HubSpot, DataSift, GoHighLevel, and other CRM platforms, enabling me to efficiently manage leads, maintain consistent follow-up, and stay highly organized in fast-paced sales environments. Throughout my career, I have consistently generated and qualified around 40 leads per month while maintaining high-quality conversations that turn into real opportunities. I focus on building genuine connections with property owners, understanding seller situations, and creating value in every interaction rather than simply pushing for quick outcomes. Beyond lead generation, I manage the full lead lifecycle from the first contact to preparing offers. This includes identifying motivated sellers, building strong rapport, handling objections naturally, running comps, analyzing ARV, and helping move deals toward closing. I understand how to read situations, adapt my approach, and focus on what actually gets deals done. Currently, I work as an SDR, focusing on prospecting, qualifying leads, following up with prospects, and building a strong sales pipeline by identifying real opportunities. I also have experience as a Sales Specialist with Sunrun, where I educated homeowners about residential solar programs, qualified their interest, and scheduled appointments with energy consultants to help them find the best solution for their homes. I also worked as an SDR and Appointment Setter for Leads To Closings, where I handled warm lead follow-ups, qualified prospects, handled objections, and booked appointments directly on the client's calendar while keeping lead information and outcomes updated in the CRM. Additionally, as a Sales Executive at Virtual Landscape Design - Australia, I work closely with clients to understand their vision, budget, and needs, helping them choose the most suitable landscape design solutions while guiding them through the decision-making process. Beyond work, my experience with Enactus played a major role in shaping my mindset. As Head of the Graphic Design Committee, I contributed to my team's achievement of 1st place in Egypt and 1st place globally at the Enactus World Cup through our project Hermetia, which focused on sustainable solutions. I'm always eager to learn, take on new challenges, and contribute to teams where I can create value, build lasting relationships, and drive measurable business growth.

What does a Development consultant do?

A development consultant acts as a strategic advisor who translates business requirements into actionable software delivery plans across the full software development life cycle. This role bridges the gap between high-level product goals and technical execution by defining clear roadmaps, configuring project workflows, and establishing deployment standards. Rather than writing code directly, this professional assesses feasibility, maps team processes, and guides organizations through planning, design, implementation, testing, and deployment phases. The focus remains on optimizing how teams build and ship applications while ensuring alignment between technical output and business objectives.

  • Evaluate software needs and project feasibility to create detailed execution plans that cover every stage from initial design to final deployment. This involves assessing current technical capabilities, identifying gaps in the development process, and defining specific milestones that keep the project on track. The consultant produces a comprehensive roadmap that outlines goals, deliverables, and timelines to ensure all stakeholders understand the path forward.
  • Design and configure team workflows within project management tools like Jira to reflect how work moves through development and quality assurance stages. This includes setting up status transitions, defining rules for issue tracking, and connecting development tools such as GitHub to capture real-time progress. By mapping these processes clearly, the consultant ensures that every code commit, pull request, and test result links back to specific project requirements.
  • Establish deployment practices and tracking mechanisms that allow teams to monitor release events and maintain visibility into production changes. This work involves guiding the integration of development tools with project boards so that deployment data appears automatically alongside task updates. The consultant also defines standards for code review and release contributions using platforms like GitHub Issues and Pull Requests to maintain quality control throughout the delivery pipeline.

How to hire a Development consultant on Upwork

Step 1: Post a job

Define your software lifecycle needs and project goals clearly to attract qualified advisors. Use the Job Post Generator powered by Umaโ„ข, Upwork's Mindful AI to draft a precise description. Describe your requirements in a few sentences, and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify whether you need help with SDLC planning, feasibility assessments, or deployment strategy execution.
  • List required tools such as Jira for roadmapping or GitHub for issue tracking and pull request management.
  • Include expected deliverables like workflow definitions, milestone timelines, or toolchain integration plans.

Step 2: Evaluate candidates

Review portfolios for evidence of structured software delivery and clear technical documentation. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to speed up your review process.

  • Look for sample roadmaps that show goals, milestones, and timelines aligned with business objectives.
  • Check for workflow diagrams that map status transitions from development through testing to deployment.
  • Verify experience connecting development tools to project management platforms for accurate progress tracking.

Step 3: Interview your top choices

Discuss their approach to translating business needs into actionable technical plans. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session.

  • Ask how they configure Jira workflows to reflect specific team processes and quality gates.
  • Request examples of how they managed code reviews and release contributions using GitHub Pull Requests.
  • Explore their method for assessing software feasibility and defining realistic implementation phases.

Step 4: Agree on scope and begin work

Finalize deliverables such as SDLC execution plans or deployment guidance before starting. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Set milestones for completing roadmap drafts, workflow configurations, or toolchain integrations.
  • Define acceptance criteria for each deliverable to ensure alignment with your technical standards.
  • Establish regular check-in points to review progress against the agreed-upon project timeline.
