I’m an experienced software engineer with many years in the industry, including time at Google. I have strong expertise in Java, Python, and AWS, and I enjoy solving complex problems. I focus on building the right solutions, simplifying systems, and reducing complexity and cost. I’m looking to work on projects where I can use my skills and problem-solving mindset to create efficient and scalable software.
Great coders - replaced by AI circa late 2025. Great dev ops - replaced by AI circa mid 2026. Great software engineers - not yet! I am all three, and have been for many years. I solve problems, fast. Is yours next? Checkr background fully green. AI Systems Architect, GTME, CSA, SRE, and Fractional CTO helping organizations leverage custom AI, autonomous agents, and cloud infrastructure to build products faster, automate operations, and scale efficiently. Expert in custom AI model development, fine-tuning, RAG implementations, multi-agent systems, AI-powered workflow automation, LLM integration, cloud architecture, cybersecurity, and high-availability SaaS operations. With decades of hands-on engineering experience and deep expertise in modern AI tooling, I bridge the gap between traditional software engineering and next-generation AI systems. I build production-ready AI solutions that deliver measurable business outcomes—not demos, prototypes, or hype. From custom AI platforms and autonomous agent ecosystems to cloud-native SaaS infrastructure and mission-critical production environments, I help organizations deploy secure, scalable systems that create immediate operational leverage. Extensive NDA obligations limit what I can publicly share, but my experience spans startups, growth-stage companies, enterprise organizations, and large-scale SaaS platforms operating under demanding uptime, privacy, and security requirements.
I build the execution, data and backtesting infrastructure that lets a trading strategy run unattended, plus the LLM and agent systems around it, inside your repo, without needing your alpha. Lead developer at a Swiss fintech building automated trading systems. Founder and lead developer of a finance-and-AI software consultancy. Author of a Python open-source project with ~37,000 GitHub stars, featured on the Hacker News front page four times and endorsed by Mr Andrej Karpathy, co-founder of OpenAI. Published the video course "Hands-on Reinforcement Learning with TensorFlow" with Packt. I do not build "guaranteed profit" bots or sell signals. I build the systems that run yours safely, and I will tell you in the first fifteen minutes whether what you have is an infrastructure problem or a strategy problem. What people book me for: - Trading-system architecture and execution-path review: order management, partial fills and all-or-none orders, reconciliation after disconnects, persistent order state, kill switches, paper-trade-first deployment. - Exchange and broker connectivity: WebSocket and REST integrations (Alpaca, CCXT-supported venues, Binance), rate limits, idempotent order submission. - Backtesting infrastructure and the backtest-versus-live gap: fills, slippage and latency assumptions, replay fidelity, parameter search without overfitting. - Market making and liquidity tooling across venues. - LLM and agent systems for finance workflows: orchestration, evaluation pipelines, tool-use design, reinforcement-learning approaches where they actually fit. - Python systems engineering: asyncio, PostgreSQL, FastAPI and Django, production reliability. How a first session usually goes: you share the repository or a design, I ask three questions (budget and timeline; whether you already own the strategy, accounts and data; whether you want infrastructure or "a profitable bot"), and we spend the rest of the hour on the highest-risk part of your system. Longer work continues as a fixed-scope code-review job or an hourly engagement on this platform. Based in Bengaluru (IST), with daily overlap with European hours and the US-East morning. I reply to trading, fintech and AI requests within minutes when online. More at https://satwikkansal.xyz | Consultancy: https://zobyt.com
Hi there! It's Ale. I'm a software engineer with nearly twenty years of experience helping companies build amazing products. I feel at home with **Ruby on Rails** and **Elixir/Phoenix**, but I’ve also delivered high-quality code in **Node**, **React**, and **Python**. Over the years, I’ve been the first technical hire, a full-stack developer, a tech lead, and pretty much everything in between. I'm used to working closely with founders and small teams, moving from Plan A to Plan B to whatever plan actually gets us across the finish line. I've helped startups build and scale web applications across finance, e‑commerce, esports, logistics, automotive, healthcare, edtech, and even the fashion industry. I have experience with high-profile web apps serving millions of users and smaller platforms with modest traffic but incredible revenue. I've helped companies launch SaaS products and ad-supported platforms in both B2B and B2C spaces. Lately, I’ve been focused on integrating AI into web apps across esports, e-commerce, and fintech. If you're building epic stuff, don’t hesitate to reach out. Whether you're looking for a full-time hire or a part-time consultant. I'm always up for a new challenge and would love to chat. Some apps I helped build: * [AirOps (Ruby On Rails - React - AI)](https://www.airops.com/) * [Canary Data (Elixir/Phoenix - React - AI)](https://canary-data.com/) * [Blitz (Elixir/Phoenix - AI)](https://blitz.gg/) * [Superkind (Elixir/Phoenix/LiveView - AI)](https://www.linkedin.com/company/superkind) * [ZenMaid (Ruby On Rails - React)](https://get.zenmaid.com/) * [About Fresh (Elixir/Phoenix/LiveView)](https://aboutfresh.org/) * [AR Workflow (Ruby On Rails - Node.js)](https://arworkflow.com/) * [SnapCell (Ruby On Rails)](https://snapcell.us.com/) * [Stash (Node.js - Python/Django)](https://stash.com.ar/) * [Walkboard (Python/Django)](https://www.walkboard.com/) * [Sky Sports (Node.js - Python)](https://www.skysports.com/football) I wrote [Data Structures From Scratch](https://www.amazon.com/gp/product/B07MZZT6SW), an ebook that explains how to create essential, advanced, and persistent data structures in Ruby. I live in Buenos Aires (UTC-3) with my wife and beautiful son.
