I’m seeking a reliable developer who can keep our in-house accounting system running at peak performance under a retainer model. The arrangement is straightforward: a fixed $800 each month secures your availability; workload fluctuates from a few hours to a few days depending on what needs attention, yet the payment stays constant. The core focus is performance optimization. Right now the data-scraper that feeds transactions into the ledger has begun to slow under heavier volumes, so your first mission will be to streamline its execution, cut any wasteful memory use, and ensure it responds instantly to user requests. You’ll profile existing code, implement targeted improvements, and deploy clean, well-documented updates. While the main priority is speed and efficiency, there may be occasions when a quick bug fix or minor enhancement is required—nothing outside normal upkeep of an accounting platform. Each time you touch the code I’ll expect: • Updated module committed to our repo • A concise change log outlining what was modified and why • A simple before/after performance snapshot Please be reachable within 24 hours on weekdays and able to push critical patches within 48 hours when needed. If you have a proven track record of squeezing every millisecond out of financial or accounting software, I’d like to get you started this month.
