I help international businesses fix two expensive problems: payment costs they don't know they're paying, and finance operations that cost too much to run in-house. My background is unusual: 4 years in Stripe's Strategy & Analytics org, tax advisory at KPMG, and I'm a Chartered Accountant (India's CPA equivalent). I've seen payments from inside the processor and finance from inside a Big 4. Payments & Stripe consulting At Stripe, I quantified $600K in FX fee savings for a $185M-volume platform and built an auth benchmarking framework used 450+ times internally. For clients: Payment cost audits find where you're overpaying on interchange, FX, and cross-border fees Authorization rate optimization Payments stack decisions: Stripe vs. Adyen, MoR vs. direct, multi-currency architecture Stripe implementation reviews: Billing, Connect, Radar Offshore accounting & fractional CFO I run an advisory practice with a trained team - Big 4 process discipline at offshore rates: Bookkeeping, month-end close, and reporting (QuickBooks/Xero) Fractional CFO: financial models, investor-ready reporting, KPI dashboards India subsidiary? Compliance, payroll, and entity management handled end-to-end You get quantified findings and clear advisory notes, not just filed paperwork. Based in India with strong US/EU hours overlap. Processing $1M+/year and never audited your effective rates? Start there I'll either find you money or confirm you're clean.

Java Backend Engineer | Microservices · Spring Boot · Fintech & Enterprise Systems I build backend systems that handle real load — trading platforms, HR infrastructure, and e-commerce — with a focus on reliability, observability, and clean architecture. Over 4 years across fintech companies (Flatex DeGiro, ThinkMarkets, UKG), I've shipped production features across dozens of release cycles with zero rollbacks, cut incident diagnosis time from 3+ days to under 8 hours through distributed tracing, and optimized database queries reducing execution time by up to 60%. My core stack: Java · Spring Boot · Microservices · PostgreSQL · Elasticsearch · Kafka · Redis · Docker What I bring to freelance projects: Microservice design and implementation from scratch REST API development and third-party integrations Performance optimization (DB queries, caching, indexing) CI/CD setup with Jenkins and Docker Production-grade code with proper testing (JUnit 5, Mockito) I also built and shipped my own e-commerce platform end-to-end (shisharkaa.bg) — Adyen payments, Econt logistics, Redis caching, JWT auth — so I know what it takes to own a project fully, not just contribute to one. If you need a backend engineer who ships clean, tested, production-ready code — let's talk.

🏆 Building an AI app with Lovable, Base44, Replit, or Claude Code is easier than ever. Getting an AI app into production is where most projects get stuck. Most are built with React, Next.js, TypeScript, Node.js, Python, Supabase, PostgreSQL, Stripe, and Capacitor but production introduces a completely different set of problems. That's where I help. By the time clients reach out, they already have something valuable. The MVP works. Users have signed up. Payments are almost working. The demo impressed investors. But production is a different challenge. A deployment breaks authentication. A Supabase Row Level Security (RLS) policy blocks legitimate users. Stripe subscriptions stop activating. A React or Next.js update introduces unexpected regressions. Capacitor builds fail App Store review. AI outputs become inconsistent under real user traffic. Most founders think they need to rebuild. Most don't. I help founders turn AI apps built with Lovable, Base44, Replit, and Claude Code into stable, production-ready software. Most of those applications are powered by React, Next.js, TypeScript, Node.js, Python, Supabase, PostgreSQL, Firebase, and modern AI frameworks and that's where I spend most of my time. 🎯Key Milestones ◉ Rescued 32 Lovable, Base44, Replit, and Claude Code applications across SaaS startups, internal business tools, and customer-facing platforms that had stalled before production launch. ◉ Resolved 85+ React, Next.js, Supabase, PostgreSQL, authentication, Edge Function, and Row Level Security (RLS) issues across existing client applications ◉ Stabilized 48 Stripe Billing, Stripe Connect, subscription, and webhook failures across 20+ client projects without disrupting active customer payments. ◉ Wrapped and deployed 21 React and Next.js web applications with Capacitor, successfully shipping to the App Store and Google Play while resolving 15+ App Store review issues. ◉ Setup and deployed 40+ AI agents, AI workflows, RAG pipelines, MCP integrations, and business automations using OpenAI, Anthropic Claude, LangChain, LangGraph, CrewAI, Hermes Agent, and the Claude Agent SDK, reducing manual work by an average of 45%. 🛠️ What I Help With ◉ AI app rescue and production hardening for Lovable, Base44, Replit, Claude Code, Cursor, and Bolt.new projects. ◉ React, Next.js, TypeScript, Node.js, Python, and FastAPI development for AI SaaS products and customer-facing platforms. ◉ Supabase architecture, PostgreSQL design, Firebase, authentication, Edge Functions, Row Level Security (RLS), and production database optimization. ◉ AI agent development, AI workflow automation, RAG systems, MCP integrations, OpenAI API, Anthropic Claude, LangChain, LangGraph, CrewAI, prompt engineering, and LLM integrations. ◉ Stripe subscriptions, Stripe Connect, payment gateways, recurring billing, customer portals, webhook debugging, and RevenueCat integrations. ◉ Capacitor, React Native, Flutter, Expo, iOS, Android, TestFlight, App Store Connect, Google Play Console, push notifications, deep linking, camera access, GPS, and biometric authentication. ◉ Production debugging, deployment pipelines, CI/CD, Docker, Vercel, Railway, AWS, Google Cloud, GitHub Actions, monitoring, logging, and performance optimization. ◉ WordPress, Base44, and Replit migrations into scalable React, Next.js, Supabase, PostgreSQL, and cloud-native architectures. 🧰 Tech Stack Frontend: React, Next.js, TypeScript, Tailwind CSS, Vite, Vue.js Backend: Node.js, Python, FastAPI, Supabase Edge Functions, REST APIs AI: OpenAI, Anthropic Claude, Google Gemini, LangChain, LangGraph, CrewAI, Claude Agent SDK, RAG, MCP Mobile: React Native, Flutter, Capacitor, Expo, Swift, Kotlin Database: PostgreSQL, Supabase, MySQL, MongoDB, Redis Cloud: AWS, Vercel, Railway, Docker, Google Cloud Payments: Stripe, Stripe Connect, RevenueCat, PayPal Authentication: Supabase Auth, Firebase Auth, Clerk, Auth0 Platforms: Lovable, Base44, Replit, Claude Code, Cursor, Bolt.new If your AI built app is close to launch but production bugs, deployment issues, security concerns, or technical debt are getting in the way, send me the details.

I'm a backend engineer at QuillBot (one of the world's most-used AI writing tools, 1M+ daily active users), where I own the entire payments infrastructure — Razorpay, Stripe, Adyen, and Chargebee, plus an in-house subscription management system I wrote from scratch. What that means practically: I've solved every hard problem in production billing. Webhook idempotency at scale, failed payment recovery, upgrade/downgrade proration, cross-provider state sync, dunning flows, entitlement management — all running against $50k+ MRR without interruption. Before QuillBot, I was at Mable GmbH building data pipelines that processed millions of analytics events per day for 30+ enterprise customers using Go microservices, ClickHouse, and GCP Pub/Sub. I also built a server-side ad attribution system that drove a 35% boost in ad performance. At Copycat.dev I rewrote a Python backend in Rust — 18x faster. My stack: - Payments: Razorpay (wrote), Stripe, Adyen, Chargebee (maintained) - Backend: TypeScript (NestJS), Go, Rust, Python - Workers/Queues: BullMQ - Observability: OpenTelemetry - Infra: Kubernetes, ArgoCD, Docker, GCP, AWS - Databases: PostgreSQL, ClickHouse, Redis, MongoDB, ArangoDB I freelance 5-10 hrs/week for startups that need senior backend engineering without a full-time hire. My sweet spot: payments systems, subscription infrastructure, and high-throughput data pipelines. If you're building something that needs to be reliable at scale — let's talk.

I'm an FP&A and financial modeling specialist. I build Excel, Python, and Google Sheets systems for cash flow forecasting, financial models, dashboards, and reporting automation—so your team can run them without me. Too often, someone exports the same data every week, rebuilds the same report, and re-explains the same numbers. I replace that cycle with a reliable workflow your team can refresh, audit, and own. 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱: • Cash flow forecasts — 13-week rolling and 12-month models for runway, liquidity, collections, working capital, and scenario planning. On one engagement, the first run surfaced €35,200 in stuck revenue by flagging disputed invoices and unapproved payables. • FP&A dashboards and reporting automation — budget vs. actuals, KPI tracking, variance and management reporting, and repeatable refresh workflows. One client's weekly reporting dropped from about 4 hours to under 20 minutes. • Financial models — DCF, IRR, pricing, investor-ready projections, and scenario/sensitivity models built for real decisions, not just presentation. I hold the Financial Modeling & Valuation Analyst (FMVA®) certification. • Model audits, rebuilds, and team handover — I clean up inherited files, restructure the logic, add validation checks and clear guidance, and coach teams to run the model with confidence. I'm currently supporting an ongoing Excel and Python coaching engagement for financial performance reporting. I also support survey and research data analysis, plus procurement and pricing benchmark frameworks, when a project calls for them. Clients have endorsed my Survey Data Analysis, Quantitative Analysis, and Statistical Analysis, and one client rehired me for their 2027 report. 𝗕𝗲𝘀𝘁 𝗳𝗶𝘁: Finance, operations, and founder-led teams at 10–200-person SMBs that need reliable decision-support systems—not another fragile spreadsheet only one person understands. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸: Async-first. You send the current workbook or dataset, the existing process, and the decision the output needs to support. I confirm scope in writing, separate inputs, calculations, and outputs, add validation checks and clear notes, and hand over the finished system with a walkthrough. Tools I use as needed: Excel, Google Sheets, Power Query, VBA, Apps Script, and Python. 𝗧𝗼 𝘀𝘁𝗮𝗿𝘁, 𝘀𝗲𝗻𝗱 𝗺𝗲: • your current workbook or dataset • one question it can't answer today • your deadline I'll review it and tell you honestly whether I'm the right fit. If I'm not, I'll say so before you spend time or money.
