Founding Engineer focused on building and scaling production systems from 0→1, with a strong emphasis on distributed system design, AI-driven workflows, and real-world reliability under constraint. I work across the stack (backend, frontend, infrastructure), but my primary focus is designing systems that behave correctly under real usage. Recently, I’ve been building AI-native systems including: - LLM-powered workflows and agents (Gemini, LangChain), with emphasis on controlling non-determinism in production systems - conversational interfaces (e.g. WhatsApp-based onboarding and automation), with stateful multi-step user flows and reliability guarantees - systems where AI is embedded into core product logic, not just a feature layer At early-stage startups, I’ve: - designed and shipped full-stack distributed systems from idea → production → real users - owned system behavior end-to-end (API design, backend architecture, infrastructure, billing logic) - worked directly with users to understand failure cases and iterate on system reliability - made tradeoffs between speed, correctness, and scalability in production environments I enjoy environments where: - engineers own systems, not tickets - product and system design are tightly coupled - shipping quickly does not mean sacrificing correctness - ambiguity is treated as a design constraint, not a blocker Previously, I led engineering teams and large-scale systems at Accenture, but I prefer early-stage environments where I can design, build, and operate systems end-to-end with high autonomy.
Founding engineer building an AI-native scheduling and coordination platform from 0→1, currently serving ~2K active users. I own the full system stack (backend, frontend, infrastructure, and product), with a strong focus on building reliable AI-driven workflows in production. Key work: - Designed AI scheduling engine using Gemini (Vertex AI) + LangChain, with emphasis on handling non-deterministic LLM outputs through structured validation, guardrails, and fallback logic - Built WhatsApp-based conversational system for onboarding and scheduling, handling asynchronous flows, retries, and state consistency across multi-step interactions - Architected backend system (NestJS) with idempotent workflows and resilience against duplicate and delayed requests - Designed GCP infrastructure for real-time AI workloads with attention to latency and scaling constraints - Implemented Stripe-based billing system with consistent state management across usage and subscriptions - Built extensibility layer (MCP server) for external integrations and future platform growth I work closely with users and iterate quickly, but with strong attention to system correctness, reliability, and failure handling in production environments.
