From 44,374 reviews, clients rate our SQLite Professionals 4.9 out of 5 stars.I want a clean, well-documented Python application that plugs into the Fyers REST API and runs a fully automated intraday strategy. The logic is straightforward: a Moving Averages crossover confirmed by a Relative Strength Index (RSI) filter triggers entries, then the system exits when the opposite MA crossover appears or a user-defined RSI level is hit. Time-frames (1-min, 5-min, etc.) and all indicator parameters should be editable from a single config file so I can tweak the behaviour without touching the code. The program must: • Authenticate to Fyers using my API keys, refresh tokens automatically, and reconnect on dropouts. • Stream live market data, compute the MAs and RSI in real time (pandas_ta or TA-Lib are fine), and generate long/short orders the instant conditions...

I need a reliable way to confirm whether a given high-net-worth individual is associated with my freemasonry verification service. For every millionaire in the list I supply—or that you source—you will provide both a verifiable street or registered business address and an official email address. The end goal is to feed those two data points into a DNS-based lookup flow similar to: Linux / Unix: `dig txt ` Windows: `nslookup -q=txt ` Because I will be running checks from machines on both platforms, the script you deliver must execute cleanly under Bash and PowerShell without any manual tweaks. An auto-detect of the OS with the right call to `dig` or `nslookup` is ideal. Deliverables: • A CSV or SQLite dataset containing each millionaire’s full name, address...
I need a streamlined Android mobile application whose core function is a clear, intuitive snack-selection menu. The flow is simple: users open the app, browse categories or search directly, tap an item, and add it to a lightweight cart. At this stage I am not including in-app payments or review screens, so your effort can stay focused on perfecting the menu experience, item imagery, and quick navigation. Key points to cover • Native Android build (Kotlin or Java—whichever you are faster with) • Simple, modern UI that fits Material 3 guidelines • Category filter, search bar, and product detail pop-ups with image, price, and short description • Local data storage or a small Firebase/SQLite back-end so items can be updated without a new APK push • Cle...

I am preparing to move a sizeable MySQL dataset—customer, product, and transaction records—to a new environment and need someone who has performed full-scale migrations before. The assignment runs for roughly one month, during which you will work from our Hyderabad office so we can iterate quickly with business owners and IT. The work covers the entire pipeline: extracting data from the current MySQL instance, scrubbing and de-duplicating it, mapping old structures to the target schema, and applying significant transformations to fit new business rules. Solid SQL is obviously essential, and you should already feel at home with large tables, indexes, constraints, and performance tuning. Experience scripting in Python or using ETL utilities (e.g., Talend, Pentaho, custom shell/P...
