I bridge the gap between complex financial logic, autonomous AI systems, and high-performance software engineering. With over 7 years of experience, I don't just write scripts; I architect institutional-grade systems—from low-latency trading engines to scalable, full-stack web platforms. 1. Quantitative & Algorithmic Trading Hybrid Low-Latency Systems: I design decoupled C++/Python architectures for MFT (Mid-Frequency Trading). My proprietary systems utilize market microstructure (order flow, book imbalances) and regime-switching models to capture alpha. Rigorous Validation: I reject simple vector backtests. I build custom Event-Driven Backtesters that pessimistically model slippage, latency, and maker/taker fees to ensure strategies are robust before deployment. Predictive ML: Expert in applying XGBoost and Scikit-learn to financial time-series data for anomaly detection and trend forecasting. 2. Generative AI & Agentic Workflows Autonomous Agents: I architect stateful, multi-agent workflows using LangChain and LangGraph. I build systems where agents reason, critique, and self-correct to automate complex enterprise tasks. Advanced RAG: Designing "Retrieval-Augmented Generation" pipelines for document intelligence, extracting structured data from unstructured financial/legal documents with high accuracy. 3. Full-Stack Engineering Foundation My math and logic skills are built on a rock-solid engineering foundation. I deliver polished, production-ready applications. Backend: Python (FastAPI, Django), Node.js/TypeScript, C++ (for performance modules). Frontend: React.js, Next.js, modern CSS (for responsive, commercial-grade UI/UX). Infrastructure: Docker, AWS/GCP, CI/CD pipelines, and SQL/NoSQL database design. A Unique Advantage As a native Thai speaker with expert-level English, I bridge the communication gap for international teams entering the Southeast Asia market or Thai projects targeting the US. If you need a developer who understands the mathematics of the market, the architecture of AI, and the engineering of the web, let's talk.

I build AI-powered intelligence systems, automation tools, data pipelines, and cloud-ready software for clients who need reliable technical execution. My background combines Python development, quantitative research, cybersecurity study, cloud infrastructure, and data engineering. I started in financial markets and algorithmic research, where I built backtesting engines, signal systems, dashboards, and market-data pipelines. That gave me a strong foundation in statistical thinking, system design, and high-stakes decision tools. Today, my work is broader: I build systems that collect, process, analyze, and explain information. What I can help with: — Python automation and backend tools — AI-assisted research and analysis systems — Data pipelines, dashboards, and reporting tools — Cloud deployment and infrastructure workflows — OSINT-style research tools and investigation workflows — Cybersecurity learning labs and security-aware tooling — API integrations, scraping, cleaning, and structured data processing — Trading, market, and financial analytics when needed I care about clean architecture, reproducible code, documented assumptions, and systems that are easy to maintain after delivery. I do not just build scripts that work once. I build tools that can be understood, extended, and trusted. My long-term focus is intelligence infrastructure: systems that help people turn fragmented information into clear decisions. If you need a technical builder who can combine AI, data, automation, and practical system design, I can help.

I build AI automation systems that replace manual operations, reduce workload, and help companies scale without increasing headcount. Over the last 8+ years, I’ve delivered production-grade systems including AI agents, workflow automation engines, voice AI systems, and real-time backend platforms used in live environments.

EX Astrophysics Researcher Now helping companies build AI systems that stay relevant long after today’s AI models become obsolete. Six months ago, everyone wanted RAG. Then Agentic RAG. Then Knowledge Graphs. Now it's Context Engineering and a new "breakthrough" every other week. Here's the uncomfortable truth: your hardest problem isn't choosing the right AI model. It's that by the time you've hired engineers to build with it, the ground has already shifted. And even if you hire brilliant engineers… Who designs the architecture? Who decides whether you need RAG, fine-tuning, or honestly just a better-engineered context? Who makes sure what you build isn't technical debt six months from now? Who connects product, data, backend, cloud, and business strategy into one system that actually ships? Most companies don't need another freelancer. You're responsible for business outcome not for building an AI team. Even if you build a great in-house team, it eats the one thing you can't buy back: your time and focus. That's where we come in. A high-paced AI consulting partner you can rely on a 40-member team covering design, engineering, research, and deployment, built to understand your business fast and own the journey. That’s exactly where we come in: Over 6 years, I’ve led cross-functional teams of designers, product managers, AI researchers, machine learning engineers, backend developers, App developers, IOT engineers, cloud architects, and DevOps specialists to build AI systems that businesses actually depend on. Whether you’re building an AI-native product, modernising an existing platform, or automating internal operations, we become an extension of your team handling everything from product strategy and AI architecture to development, deployment, optimisation, and long-term support. So instead of managing five different vendors or trying to build an expensive in-house AI team… You get one experienced partner responsible for the outcome. Btw Im Vivekjyoti Bhowmik, a 3× AI Founder who spends every day turning cutting-edge AI research into scalable products that can fit the market to solve real business problems. Today I lead three companies: → TOINGG : an AI Communication OS cum AI first CRM that have generated $700M+ in qualified sales pipeline and still counting. → PGAGI : a 40+ member AI engineering studio in Bangalore, where we design, build, and scale production-grade AI systems for startups and enterprises worldwide. (The reason you’re reading this profile.) → BigAIRLab: our AI research lab, where we continuously evaluate the latest breakthroughs and turn promising research into practical, market-ready products. :trophy: A Few Selected Results: → $700M+ qualified sales pipeline generated through AI-powered outreach, lead qualification, and automated engagement systems. → 50,000+ users in month one and $2.5M revenue generated within two months of launch for Branify, we designed and built. → 2M+ financial signals processed daily through AIMI Brain, powering real-time AI-driven market intelligence. → 45% higher email open rates and 3× faster campaign creation with Email Love, an AI platform (40K + users) for autonomous email generation and optimisation. → 45% reduction in product returns and 3× higher customer engagement with Mirror Me, an AI-powered virtual try-on platform. → 80+ production AI systems delivered across healthcare, fintech, SaaS, manufacturing, retail, and enterprise operations. → 70%+ of the AI products we build are live, actively used by real customers, and generating measurable business value. → Production-grade AI communication infrastructure built to support high-volume voice workflows with scalable cloud architecture and enterprise reliability. → Trusted by businesses across the US, UK, GCC, Africa, Australia, and India. We're a fit if: your budget is min $5,000 as we believe in quality over quantity. Honestly we have lot of invites so choose who to work for outcomeMaxing and this is must: you have 5+ years in business and atleast $1M in revenue. How we work (and why founders like it): We don't bill hourly. Hourly billing means you pay for time and hope for results Ours is different: you only pay when you get the outcome. We sit down before anything starts and map your project using our Power Law Roadmap finding the 20% of milestones that drive 80% of your business outcome. We build those first. Simple things that scale, before clever things that don't. Every milestone comes with a defined outcome, in writing. You don't approve the milestone — and don't pay it — until that outcome is in your hands. That's not a promise; that's how our contracts are structured. As a founder myself, I'll also tell you what most vendors won't: half the ideas on your list shouldn't be built yet. We'll say so. Two ways to start: 1. Message me with what you're building one paragraph is enough.
