I need a Python-based trading algorithm that trades both the Nifty and Bank Nifty indices. The code should run locally on Python (feel free to lean on pandas, NumPy, TA-Lib, backtrader or similar libraries) and must be able to import and work with historical market data only—no live feed is required for this milestone. Here is what I expect: • A clean, well-commented Python script (or notebook) that ingests historical data, generates trade signals, executes the logic, and outputs detailed performance metrics and an equity curve. • Clear instructions on how to map the code to CSVs or API endpoints I already use for historical NSE data. • A short README explaining any configurable parameters so I can tweak settings for further experiments.

I want to launch ...and a web interface. Learners will be free to type or speak, so the build needs seamless text I/O plus speech-to-text and text-to-speech hooks. I am open to whichever stack you are comfortable with—Rasa, Dialogflow CX, or a custom NLP pipeline in Python or Node.js—so long as: • the scenario engine can expand easily with new role-plays, • Hinglish code-switch detection is accurate enough to nudge, not scold, • quizzes follow a true SRS algorithm (SM-2 or similar), and • voice and text remain in sync across web and mobile. Please include a brief outline of your proposed architecture, any pretrained language models or Hindi ASR/TTS services you would leverage, and a timeline for an MVP that covers at least three role-pl...
...validated automatically so that outliers, missing values and inconsistent formats are handled without manual intervention. Once the dataset is in shape, the system must calculate core ratios—operating and EBITDA margins, liquidity and leverage indicators, year-over-year growth rates, cash conversion, risk flags—and feed them into a machine-learning pipeline. I have no fixed allegiance to any one algorithm, but I would like to begin with a solid linear regression benchmark and keep the door open for more sophisticated models if they outperform. The model should output a single “investment readiness” score for each hospital, accompanied by clear explanations that highlight drivers such as high debt, robust profitability or rapid growth. These explanati...

I have the complete source code for a mobile app and now need it published on both Google Play and the Apple App Store. The build, signing, and submission steps for APK/AAB and IPA are where I need you to jump in. Because I’m not certain which minimum Android SDK level or iOS deployment target is safest right now, I’ll rely on your recommendation there. Please suggest sensible, up-to-date version thresholds that will maximise device coverage without risking rejection. On the store-front side I’ll prepare most of the wording and graphics, but I do want partial help: a quick review of my descriptions, guidance on required screenshot sizes, and a check that the listing metadata meets each store’s rules.

I manage the website for Dura Cabs Services and I’m looking to lift our organic visitor numbers sharply. The site already has a solid design and a clear value proposition; what it lacks is a cohesive SEO strategy that blends on-page, off-page, and technical work aimed squarely at Google’s algorithm. Here’s what I need from you: first, a thorough audit that pinpoints every opportunity—from metadata and internal-link structure to page-speed, Core Web Vitals and crawl-depth issues. Once the audit is complete, I expect a step-by-step roadmap and the implementation muscle to execute it: keyword research aligned to high-intent travel terms, content optimisation (including schema markup), clean technical fixes, and a sustainable backlink programme that respects qua...

...clear, well-commented rules. • Optional if you add simple interactivity (fade-in, lightbox, or arrow navigation). • A brief README or inline comments walking me through how to swap in my own photos, change the number of columns, and how to include it in an existing html landing page. This is to go on to a white bg page. Keep everything framework-free—no Bootstrap, no jQuery—so the code stays easy to maintain and drop into any site. Aim for quick load times and sensible semantics (figure, img, figcaption where appropriate). Responsive behaviour is desirable but doesn’t need to be pixel-perfect on every device; a straightforward media query that stacks images on small screens will do. When you’re done, send a zipped package containing the ...

...especially curious to see what Pinterest can do for me. The end-goal is simple: more downloads, higher rankings on Google Play, and users who stick around and engage. Inside the store, you’ll handle full keyword research and optimisation, create eye-catching high-resolution screenshots, and reshape the long + short descriptions so they speak directly to my target audience and the Play Store algorithm. Outside the store, I need a lightweight but effective SEO campaign. That means authoritative backlinks, content pieces that funnel organic traffic to the listing, and a batch of carefully designed Pinterest pins that point straight to the install page. If you already have a proven pin strategy—or ideas on how to repurpose app visuals for Pinterest’s search—...
