I ship end-to-end SaaS for solo founders and indie operators — Stripe checkout, automated license delivery, embeddable Shadow-DOM widgets, Telegram bots and Mini Apps. One developer, one production loop, lifetime-license economics on $5 VPS.
Core Engineering Capabilities:
End-to-End SaaS Loops: Stripe → Resend → license-key delivery → domain-bound widget gating. Indie SaaS economics, not enterprise budgets.
Telegram-Native Surfaces: Python bots with multi-state ConversationHandler FSMs and fuzzy-match NLP; Telegram Mini Apps on Next.js 16 + React 19, initData-authenticated.
Browser-Based Automation: 100% client-side CSV/Excel tools — auto-column detection, real-time preview, files never leave the browser. Zero backend, zero compliance surface.
Pure-Function Domain Engines: Date and pricing logic isolated from I/O — no cron drift, no DB desync, edge cases handled mathematically.
Selected Case Highlights:
PriceShift — Cut bulk-pricing updates from 20 min to under 2 min for a 500+ SKU retailer. Non-technical operator, zero production errors since Feb 2026.
PingBoost — Stripe → Resend → license → embeddable widget loop on a $5 VPS. Replaces $19/mo SaaS widgets with a $39 lifetime license.
ByeSubs — Python bot + Next.js Mini App over one domain model. Mathematical date engine eliminates the edge cases that break spreadsheet tracking.
