Hello, I’m Ali Mukhtar. I build Python-based quantitative finance systems for firms, startups, and serious traders who need reliable infrastructure for research, backtesting, analytics, and execution. My work sits at the intersection of quant logic and production engineering. I’ve built trading platforms and finance products with FastAPI, pandas, NumPy, TA-Lib, backtrader, PostgreSQL, Redis, CCXT, Alpaca, Polygon, and AWS, including systems for backtesting, options analytics, market data pipelines, execution workflows, and performance reporting. I’m a strong fit if you need help with: ✅ Backtesting engines with realistic assumptions such as commissions, slippage, PnL, Sharpe, drawdown, and portfolio-level metrics ✅ Strategy research infrastructure using Python, pandas, NumPy, TA-Lib, and custom rule/indicator pipelines ✅ Execution and market data systems using APIs, WebSockets, async processing, and exchange/broker integrations ✅ Risk and performance analytics including trade attribution, fill analysis, reporting, and custom metrics ✅ Finance dashboards and APIs for trading, options, and market intelligence platforms ✅ Scalable backend systems built with FastAPI, PostgreSQL, Redis, multiprocessing, and cloud deployment A few examples of the systems I’ve worked on: Built backtesting platforms with realistic trade lifecycle handling, commission/slippage modeling, and 50+ performance/risk metrics Built strategy builder APIs that allow stacking indicators and testing systematic logic across historical data Built options and market analytics dashboards using Alpaca and Polygon data, including Greeks, IV, open interest, GEX, vanna, and charm views Built execution-analysis pipelines in Python to measure fill quality, VWAP, slippage, latency impact, and symbol-specific virtual fee models Built scalable trading infrastructure with isolated processes, async data ingestion, secure auth, and production deployment on AWS / Docker / Kubernetes I’m usually not the right fit for: Generic “quick script” work with no research depth Projects that ignore execution realism, slippage, or proper validation Lowest-cost shopping where engineering quality is secondary What you can expect from me: ✅ Finance-aware implementation, not just generic backend code ✅ Clean, maintainable Python code and well-structured APIs ✅ Realistic backtesting and analytics instead of inflated results ✅ Clear communication and thoughtful technical decisions ✅ A builder who understands both quant requirements and production constraints 🚀 Ready to build something serious? 📩 Send me a message and let's discuss how we can build something exceptional together!

I build scalable multi-tenant SaaS and operations platforms using Next.js, React, Node.js/NestJS, PostgreSQL and AWS. My work includes role-based access, file processing, report generation, background jobs, API integrations, payments, audit logs and mobile-ready workflows. I usually work with founders, CTOs, and product teams when: • A SaaS MVP is partially built but not ready for real users • A spreadsheet or disconnected workflow needs to become a proper operations platform • Authentication, payments, APIs, or database architecture are blocking launch • An AI-generated prototype needs a secure, maintainable backend • The previous developer left behind an unstable or undocumented system RELEVANT PRODUCT WORK VAMS ATLAS — ongoing Backend architecture for a microbiome and health data SaaS platform using NestJS, PostgreSQL/Supabase, AWS, Stripe, role-based access, file processing, audit logs, asynchronous pipelines, and report workflows. PAYACTIV Production fintech backend services involving SSO, business onboarding, payment workflows, high-volume webhooks, fallback handling, microservices, and operational reliability. MENOKIND Healthcare integration recovery involving webhook processing, patient and booking synchronization, duplicate-client reconciliation, migration analysis, and production debugging. SALESANGEL Multi-tenant AI sales CRM and voice-product workflows. I worked on the product experience and system architecture, including tenant boundaries, billing flows, AI processing, queues, retries, and backend integration points. WHAT I CAN OWN • SaaS MVP development, completion, and product rescue • Backend architecture, REST APIs, and multi-tenant databases • Supabase authentication, PostgreSQL schemas, RBAC, and RLS • AI and LLM integrations, RAG workflows, and structured processing • Stripe subscriptions, payments, entitlements, and webhooks • AWS infrastructure, Docker, background jobs, observability, and deployment • Data migrations, workflow automation, and production debugging CORE STACK Node.js, NestJS, TypeScript, Next.js, React, Python, FastAPI, Supabase, PostgreSQL, Stripe, AWS, Docker, Redis, and Elasticsearch. Send me your current stack, the main blocker, and the workflow that must work first. I will tell you what I would verify before changing the system and whether my experience fits the project.

Senior Full-Stack Developer (7+ yrs) — Python (FastAPI/Django), Node.js, React/TypeScript, AWS. Backend-heavy engineer and former CTO/Tech Lead. I build scalable fintech, healthcare, and AI platforms — real-time payments, fraud detection, HIPAA-compliant systems. Most devs at my level execute tickets. I've owned systems end-to-end — architecture, delivery, and the team — so you get senior judgment, not just code. What I build: • FinTech — real-time transaction processing, fraud/anomaly detection, Stripe & PayPal gateway integrations, reconciliation. Built PayFlowX (high-volume, low-latency payments) and an ML-driven fraud-monitoring system on Kafka + Celery. • Healthcare — HIPAA-compliant patient platforms, appointment & telehealth systems (Clinix360, Sage Health, The Therapist). • AI / LLM — OpenAI API integrations, RAG, AI-driven products (Truth Keep news-verification platform). • Scalable backends — REST & GraphQL APIs, microservices, event-driven architecture (Kafka), Redis caching, WebSockets. Stack: Python (FastAPI, Django, DRF), Node.js (Express, Nest.js), TypeScript, React, Next.js, Angular · PostgreSQL, MongoDB, Redis · AWS (EC2, ECS, Lambda, S3, RDS, API Gateway) · Docker, CI/CD. I work solo for focused builds and can scale a vetted team for larger scopes — same accountability either way. How I work: clear estimates up front, async updates you don't have to chase, and a habit of flagging risks early (load, security, scaling) before they cost you. If you're building a payments flow, an AI feature, or a backend that has to hold up under load, send me the details and I'll tell you exactly how I'd approach it.
