Top Rated Plus. Over a decade of showing up, delivering, and doing it again the next day. I am Sunita, a full-time freelancer specializing in content writing and digital marketing. My work lives at the intersection of good writing and smart marketing, content that does not just read well but actually drives traffic, builds brand presence, and converts the right people. I have been doing this long enough to know that most clients are not just looking for a writer or a marketer; instead, they want someone who understands why the content exists, who it is for, and what it needs to achieve. Content writing is where I spend most of my time: SEO blogs, articles, social media copy, and AI-generated content that gets humanized properly before it goes anywhere near a publish button. I work with ChatGPT and other AI tools, but every piece I deliver has been read, edited, and refined by a human. That distinction matters more than most clients realize until they have dealt with raw AI output that reads like a robot wrote it. On the digital marketing side, I handle social media content and strategy, email research, LinkedIn outreach, and lead generation support for brands that need their marketing function covered without hiring a full team. I know my way around CRMs, can clean and organize data without complaint, and have worked across enough industries to pick up a new niche fast. I respond quickly and flag problems before they become your problem. After 329 jobs, those habits are just how I work. 📌 What I Do → blog writing & long-form article creation → AI content writing & humanization: ChatGPT, Claude & more → Social media content writing & platform-specific copy → Digital marketing support — strategy, outreach & campaign content → LinkedIn outreach content & B2B email copy → Image editing & AI image generation for content teams → B2B lead generation, email research & data enrichment → CRM management & data cleaning 📌 Industries I Have Worked With → Digital Marketing Agencies → Healthcare & Wellness → Finance & Fintech → E-commerce & Retail → SaaS & Information Technology → Fashion & Apparel → Travel & Tourism → Food & Beverage → Lifestyle & Personal Development 📌 Why Clients Come Back → Top Rated Plus: $200K+ earned across 325 completed jobs → Fast response, clear communication, no chasing required → AI content done right, generated, humanized, edited, and publish-ready → Understands both the content and the marketing strategy behind it → Handles data, research, and CRM work with the same care as writing → Client data stays secure, always. If your brand needs content that is built to perform and a freelancer who actually delivers, send me a message. I am full-time on Upwork and available to start quickly.

If you need an indicator, hire anyone. If you need a system that survives production, keep reading. Most trading devs have built an EA. I've built prop firms, and I still run them. I'm an Algorithmic trading systems developer, having experience with MetaTrader (MT5/MT4, MQL5/MQL4), Python, and quantitative infrastructure, Expert Advisors, trading bots, prop firm platforms, backtesting engines, and AI signal generation for forex, crypto, and equities. I build these systems end to end: strategy logic, execution layer, risk engine, and the infrastructure that keeps it running when real money is on the line. Where I've done it: Prop firms (3+ built, currently managing live), challenge and evaluation engines, drawdown and rule enforcement, trader dashboards, payout logic, MT5 integration. AI-driven signal generation systems. Custom indicator platforms. Real-time alerting infrastructure. Autonomous systems that run without me watching them. The stack: • MQL5 / MQL4 - Expert Advisors, custom indicators, execution logic, backtest optimization • Python - strategy research, backtesting, broker & exchange APIs, live execution engines • AI/ML - signal generation, model integration, decision layers • The layer around it - FastAPI/Django APIs, dashboards, Telegram/Discord alerts, deployment What actually separates me: Production experience. I've watched traders find the gap in a rule engine I wrote. I've dealt with latency, slippage, broker quirks, edge cases in breach logic, the things that never appear in a backtest and always appear in week two. That's the difference between code that works and a system that holds. Tell me what you're building. I'll tell you straight whether it's feasible, where the scope will bite you, and what it'll actually take, before you spend anything.
