Along with development, I am an active trader...Hi Traders I’m Prabhath — a professional algo-trading developer specializing in MQL4/MQL5, Pine Script, Python, and C++. I build complete algorithmic solutions for MT4, MT5, and TradingView, ranging from simple indicators to complex, institutional-grade trading systems. Along with development, I am an active trader with deep experience in ICT, SMT, market structure, liquidity concepts, order flow, volatility models, and institutional methodologies. This allows me to translate trading ideas into precise, rule-based EAs and indicators that work exactly the way traders intend. What I Develop Expert Advisors (scalping, trend, grid, martingale, HFT-style logic, breakout, smart-money systems) Custom Indicators for MT4, MT5, and TradingView ICT/SMT logic: SMT divergence, inducement, liquidity grabs, displacement, FVGs, order blocks, BOS/CHOCH Dashboard systems (multi-symbol, multi-timeframe scanners) Signal systems, alert utilities, auto-execution tools TradingView Pine Script indicators and strategies Python tools for data analytics, API connections, automation, and external signal generation C++ modules for ultra-fast calculations or custom libraries Integration of MT4/MT5 with external platforms (via Python, HTTP, WebSockets, or APIs) Advanced/Institutional-Grade Work Institutional-style algorithm development High-performance execution logic Optimization-ready architectures Robust risk-management frameworks Portfolio-level systems and multi-symbol execution Data-driven strategy modelling and validation Machine-learning-assisted signals (on request) Backtesting, Optimization, Strategy Work Full backtesting (MT4/MT5 or custom Python backtesting) Walk-forward optimization Stress testing, robustness testing Strategy refinement and development consulting Conversion of manual trading rules into automated systems Translating trading concepts into measurable, programmable logic I assist clients to fix and optimize existing trading code by removing errors, correcting logic issues, and making your EA/indicator/bot stable and production-ready. My Workflow Once we discuss the project and you select me as your developer, I usually schedule a short - call to confirm every detail before starting. This ensures complete clarity around logic, risk settings, inputs, and expected behavior. You will receive: Clean, optimized, well-structured code Clear documentation and usage guidelines A full demonstration of the EA or indicator before final delivery Fast delivery — most projects complete in 2–3 days, advanced systems within a week My clients consistently appreciate my attention to detail, strong communication, and ability to convert complex trading ideas into reliable, high-quality trading tools. Thank you. less

I do not sell...I am a professional Algorithmic Trading Systems Developer specializing in designing and engineering fully automated trading strategies across multiple platforms. My core strength lies in transforming a trader’s strategy vision into a precise, rule-based, mechanically executable trading system. I do not sell strategies — I engineer them. Although my profile on this platform may appear newer, I am an established freelancer on other major freelance marketplaces with a strong portfolio and verified client reviews. You can review my portfolio to see my previous work history, complexity of projects handled, and authentic feedback from long-term clients. My responsibility is to: • Convert trading logic into clean, optimized, non-repainting code • Ensure precise execution handling (spread, slippage, broker fills, liquidity realities) • Implement structured risk management (fixed % risk, equity protection, daily DD lock, basket control) • Develop multi-position systems (DCA, hedging, layered entries, basket trailing) • Build prop-firm compliant EAs with strict survival governance • Convert TradingView (Pine Script) strategies into native MT5 EAs • Integrate Telegram, webhooks, and bridge-based automation systems • Ensure realistic backtesting using real ticks • Create dashboards, trade managers, and performance tracking tools I work extensively with: MT4 / MT5 (MQL4/MQL5), TradingView (Pine Script), cTrader, NinjaTrader, Quantower, SierraChart, ATAS, MultiCharts, Thinkorswim, and custom Python/Java automation for proprietary trading firms. My development philosophy is strict: Execution precision > marketing performance Risk control > aggressive returns Robustness > curve-fitted backtests I clearly separate: Strategy logic responsibility (client-defined) Engineering responsibility (my scope) I guarantee accurate implementation of rules. I do not guarantee profit metrics unless strategy research and optimization are explicitly part of the contract. I have delivered 1000+ automated systems including: • Price action EAs • EMA pullback engines • Donchian breakout systems • ATR-based scalpers • DCA / Martingale basket managers • Telegram signal copiers • Trade managers with equity control • Prop-firm survival EAs • Multi-account anti-correlation execution engines What defines my role most clearly: I take complex trading ideas — including multi-layer position logic, hedging mechanics, ATR systems, execution protection, session filters, and broker-specific nuances — and convert them into stable, testable, production-grade automation. I focus heavily on: • No duplicate entries • No repainting logic • Accurate SL/TP placement after broker fill • Spread and slippage awareness • Clean modular architecture I build systems designed to operate in real market conditions — not just produce attractive backtests. And most importantly, I provide long-term support. If anything needs refinement or correction, I handle it promptly. less

My core focus is designing, building, and deploying AI-driven systems—from LLM-powered agents and voice assistants to data-aware automation pipelines that integrate seamlessly with production applications. I work extensively with large language models (LLMs), retrieval-augmented generation (RAG), vector databases, embeddings, tool-calling frameworks, and agent orchestration patterns to create systems that reason, act, and scale reliably. On the backend, I build high-performance APIs and services using FastAPI, Flask, Node.js, and Django, with strong experience in async architectures, background workers, and event-driven systems. I regularly work with PostgreSQL, MySQL, Redis, MongoDB, and Neo4j, and design robust data layers using SQLAlchemy, Prisma, and ORM/DAO patterns. For AI workloads, I integrate OpenAI, Anthropic, Ollama, ElevenLabs, and custom inference pipelines, alongside Qdrant, Pinecone, FAISS, and hybrid search setups. On the frontend, I build modern, scalable interfaces using React, Next.js, Vite, Tailwind CSS, and TypeScript, with a strong emphasis on UX for AI-powered tools (real-time streaming, agent state visualization, conversation flows, and admin dashboards). For mobile, I work with React Native and cross-platform architectures to bring AI features directly into user-facing apps. Automation is a major part of my work. I design end-to-end business automation systems using Make.com, n8n, webhooks, cron jobs, message queues, and direct API integrations. This includes automating CRM workflows, email systems, call routing, lead qualification, reporting, and data synchronization across platforms like Twilio, Slack, Google Sheets, Stripe, Shopify, and internal tools. I’m highly experienced in AI voice agents and real-time systems, integrating Twilio, speech-to-text (STT), text-to-speech (TTS), streaming APIs, and conversational state management to build production-ready voice and chat agents. I also work on computer-vision and multimodal pipelines, combining vision models, tracking, and sensor data for advanced use cases. From an infrastructure and MLOps perspective, I deploy and scale systems using Docker, Linux servers, cloud VPS, CI/CD pipelines, and GPU-accelerated environments. I care deeply about observability, logging, error handling, security, and cost optimization in AI systems. Above all, I love turning business problems into automated, intelligent systems—reducing operational friction, increasing efficiency, and building products where AI is not a feature, but a core capability. If you need AI agents, automation pipelines, or full-stack systems that actually work in production, that’s exactly what I build. less
