I’m building a net-new Salesforce application and need an APEX developer who can take it from concept to deployment. The core objective is to stand up a custom solution—not tweak standard objects—so strong experience writing scalable APEX classes, triggers, and Lightning components is essential. Here’s what I’m after: • Automated workflows – We’ll start by mapping the business processes together, then you’ll translate them into Flow or APEX-driven automations that run reliably at scale. • Custom user interfaces – Expect to design and code responsive Lightning pages/components that make the UX intuitive for end users. • Oracle API integration – The app must push and pull data to an existing Oracle system via REST, so you’ll develop secure callouts, handle authentication, and manage upserts with proper error handling. Because no detailed documentation exists yet, I’ll rely on you to help capture requirements, propose technical approaches, and produce lightweight specifications before you code. Unit tests (75%+ coverage), clear inline comments, and a short hand-off guide are part of the acceptance criteria. If your background includes deep APEX, Lightning Web Components, SOQL optimization, and hands-on Oracle or other ERP integrations, let’s discuss timelines and a milestone plan.

Hello, I will build your net-new Salesforce app: custom APEX classes and triggers, responsive Lightning Web Components, and the Oracle REST integration with secure auth and error handling. On a similar Oracle callout project, building a retry queue for failed upserts saved hours of manual reconciliation. I will set yours up the same way. Questions: 1) Is the Oracle system already exposing REST endpoints, or do those need to be built on that side too? 2) How many distinct user roles will interact with the Lightning UI? Send me a message and we can go over the details. Best regards, Kamran

Hi, I've read requirements and ready to build a custom Salesforce application from concept to deployment. Given the complexity of integrating with an existing Oracle system and the need for automated workflows, I foresee challenges in ensuring seamless data flow and user experience. To mitigate this, I propose regular check-ins to align on requirements and adjust our approach as needed. My approach will involve: - Collaborating closely with you to map out business processes and translate them into scalable APEX classes and Flow automations. - Designing responsive Lightning components that enhance user experience while ensuring they are intuitive. - Developing secure REST API callouts for Oracle integration, focusing on robust error handling and authentication. - Implementing unit tests to ensure at least 75% coverage, along with clear inline comments and a hand-off guide for future reference. If you have any specific questions or need clarification on any aspect, please let me know. Looking forward to discussing this further.

Interesting project, We will build your custom Salesforce app: Apex classes, triggers, LWC interfaces, and the Oracle REST integration. For the Oracle callouts, we will use named credentials for auth and a queueable chain for bulk upserts. This keeps governor limits safe and makes retry logic straightforward. A couple of quick things to confirm: 1) Is the Oracle endpoint already exposed, or do we need to coordinate that setup? 2) Which Salesforce edition and org type (sandbox, dev) are we working in? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to potentially working together. Thanks, Faizan

Hello there, You need a Salesforce app built from scratch with strong APEX classes and Lightning components, which fits perfectly with my Salesforce app development experience. I've built the 'Custom CRM Solution' where I developed scalable APEX triggers and designed responsive Lightning pages that improved user interaction. Here’s how I’d tackle this: first, map your workflows to ensure automation reliability; second, develop responsive Lightning components for an intuitive UX; third, handle Oracle API integration securely with robust error management. I’d start by outlining lightweight specs by next week, then proceed to development with regular reviews. If you haven’t set a budget or timeline yet, we can establish that in our first chat. What’s the main business goal you want this Salesforce app to achieve first? Best,

Hi, you’re building a net-new Salesforce app from the ground up, so the real work is turning loose business ideas into a reliable APEX solution, not patching standard objects. I’ve built custom Salesforce automation, APEX classes and triggers, and Lightning Web Components for teams that needed scalable behavior, clean UX, and solid data handling. I’m also comfortable with SOQL tuning, secure REST callouts, and Oracle-style integrations where authentication, upserts, and error handling need to be done properly. My approach would be to help capture requirements first, then map the workflows into lightweight specs before coding. From there I’d build the automation, UI, and integration layers in small milestones, with unit tests and inline comments throughout so the hand-off is straightforward. If that sounds aligned, I’d be glad to discuss the first milestone and timeline. Best regards, Gabriel
