Profile

Senior Engineer with 8+ years of commercial experience specializing in complex Vue/​Nuxt architecture, legacy
rescue, and cost-effective AI automation. I operate as an independent R&D consultant at the intersection of frontend
infrastructure, self-hosted n8n workflows, and structured LLM systems.
I deliver maximum value when a platform faces heavy performance bottlenecks, unstable integrations, or when a
business needs to automate manual processes by up to 90% without blowing up the cloud budget. I focus on
technical pragmatism, clear trade-offs, and building reliable, scalable systems.

R&D Focus

Problem Solving Philosophy
I take on problems where shipping a feature is not enough and the real task is understanding why the system is
•

inefficient or unstable.
I work well at the intersection of frontend, integrations, data flow, product logic, and automation.
•

I am pragmatic in technical decisions: if an agent-first or more elegant-looking architecture does not create a real
•

advantage, I replace it with a simpler and more reliable solution.
I often add value not only through code, but by proposing a better feature direction, a cheaper technical path, or a
•

stronger balance between speed and reliability.

Experience

Jul 2023 – Present Senior Frontend & AI R&D Consultant, (Project-based / Freelance)
Partnering with diverse businesses to solve complex technical bottlenecks, rescue legacy
codebases, and introduce modern AI workflows. This format allows me to deliver
concentrated value — setting up architecture, stabilizing pipelines, and automating processes
before handing the polished systems over to internal teams for long-term maintenance

Jul 2025 – Senior Frontend Engineer, AIScreen — A digital signage product with its own graphic
May 2026 editor, player, and manager UI for building and previewing templates.
Architected and independently delivered two core product modules from scratch: a complex
Canva-like graphic editor and a comprehensive VideoWall module. Instead of simple
visualization, I integrated the core player engine directly into the Manager UI, enabling real-
time, highly accurate live previews of complex slide transitions, element animations, and
transformation logic. The solution seamlessly processes third-party media APIs (Pexels, Giphy,
Unsplash) while maintaining high performance.

Oct 2024 – Senior Frontend Engineer, 12Go — A travel product with an older codebase where
Apr 2025 TypeScript had been partially disabled under deadline pressure.
Played a key role in unblocking and stabilizing a legacy Vue/​Nuxt codebase that had
degraded under strict deadline pressures. By systematically enforcing strict TypeScript
standards and fixing profound architectural issues across ~150 critical files, I significantly
improved the maintainability of the product and stabilized the overall CI pipeline. This effort
allowed the team to close out a significant portion of the stalled product backlog.
/​/​Vue, Nuxt, TypeScript, CI/​pipeline stabilization

Nov 2023 – Senior Frontend Engineer, Aibuy — A large long-running platform with heavy legacy code,
Oct 2024 several earlier rewrite attempts, and a complicated player-centered architecture.
Took full technical ownership of a massive, long-running platform following a handover from
an outstaffed team. I successfully stabilized the volatile codebase, organized the maintenance
workflows, and restored a robust testing environment. Beyond resolving critical architectural
bottlenecks, I drove the technical planning, streamlined deployment flows, and effectively
onboarded new engineers. Additionally, I rapidly adopted Astro to develop and deliver a
high-performance landing page under tight product constraints.

applications.
Core frontend engineer across several long-running systems, including mentoring, project
estimation, technical interviews, and stabilization of difficult codebases.
Worked through the full delivery cycle on 10+ projects in roles ranging from core frontend
•

developer to strong delivery contributor.
Contributed to long-running products, migrations, performance optimization, mentoring,
•

technical interviews, and estimation.
Common project types included form builders, analytics UI, data-heavy systems,

 AI Automation & Agents

Apr 2026 – Threads / RSS Pipeline, AI Workflow Architect
May 2026 Built a highly stable, automated news curation pipeline targeting the Threads API. The system
aggregates data from national portals, converts HTML to clean Markdown, and leverages
Gemini Flash 3 to generate engaging posts with strict JSON outputs. Integrated an
asynchronous "Human-In-The-Loop" mechanism via Telegram for draft approval/​rejection and
built an internal n8n deduplication engine. The pipeline captured massive organic traction,
generating nearly 400k views in its first week.

Mar 2026 – Real Estate Lead Enrichment, Lead AI Automation Engineer
Apr 2026 Developed a production-ready, multi-source data orchestration pipeline for a Canadian Real
Estate client, reducing manual pre-call research time by over 90% (down to 60-120 seconds
per lookup). Bypassed expensive scraping services by building a custom session-managed
access layer with auto-healing for a closed real estate system. Enforced strict JSON schemas
during LLM extraction and hosted everything on self-managed n8n, cutting operational
infrastructure costs by 95% (~$0.02 per request).

Aug 2025 – Bzhéla, AI Architecture & Infrastructure Lead
Apr 2026 Architected a fully autonomous, context-aware Telegram agent deployed on self-hosted
Android infrastructure (Termux, proot Ubuntu, Zero Trust). Engineered a custom dual-layer
memory stack using Redis for short-term history and Pinecone for long-term vector storage.
Implemented a dynamic summarization pipeline to prevent context window degradation
during active group chats. Deeply integrated the agent with regional power outage
schedules, Google Calendars, and iOS Shortcuts via webhooks to monitor hardware
telemetry.

Telegram Mini App for MLM, An MVP for product tracking and referral logic. It started as
an agent-first concept, but I deliberately replaced it with a more reliable Mini App approach.
/​/​Telegram Mini App, Vue, n8n, PostgreSQL, webhook/​API layer, crypto verification,
recursive queries
Removed the agent-first approach as soon as it became clear that it introduced
•

hallucinations and unnecessary friction.
Built the Mini App around a transactional model, referral structure, and recursive query
•

logic.
Implemented a simple API layer and Telegram init data verification with 6-8 request types, 4
•

core tables, and a referral tree up to 3 levels deep.
Built the MVP in about ~2 weeks of active development.
•

Horeca AI Agent Prototype, An early AI prototype for HoReCa workflows where the agent
acted as a layer between the customer and the business: menu, request intake, and handoff.
/​/​Telegram, AI agent flows, multi-tenant thinking, order intake scenarios
Tested how agent logic could move from personal tooling into a business-facing scenario.
•

Designed a multi-tenant model for at least 2 venues and a handoff flow where the bot first
•

replied to the customer and then sent order confirmation 5-10 seconds later.

Gustav / Hospitality Ops Automation,
An example of operational automation for a hotel / hospitality workflow
/​/​Telegram, multi-account monitoring, staff alerts, weekly reporting
Built Telegram-first operational tooling instead of a heavier system.
•

Made it possible to manage 10-20 numbers/​accounts in one place and reduce manual
•

monitoring.
Worked with monitoring, filtering, alerts, and weekly reporting; the summary flow saved
•

around ~20 minutes of manager time.

Other Projects (Out-Source)

Muso.ai, Nuxt 2, Nuxt 3, migration, analytics UI, legacy refactoring
Over ~10 months, migrated an intellectual property platform from Nuxt 2 to Nuxt 3, performed deep legacy
refactoring, and rewrote parts of the analytics/​UI logic.

Autobound.ai, Vue 3, Cypress, builder logic, sales automation
Over ~1.5 years, worked on builder-style logic for sales automation, migration to Vue 3, and coverage of critical
flows with Cypress.

Pristo, Form builder, conditional logic, validation, MediaRecorder API
Built a complex multi-step form builder with conditional logic, validation dependencies, and MediaRecorder
integration.

Aegis, Routing architecture, sidebar UX, application structure
Implemented a dual-router architecture for a more flexible sidebar UX and better separation of application logic.

Malam Payroll, Legacy refactoring, Service Workers, performance
Refactored a legacy HR platform and added Service Worker caching to improve loading speed in a heavy
application.

Millers, Data-heavy frontend, WebWorkers, indexing, performance optimization
Worked with data from ~7 endpoints, where individual arrays contained 10k to 400k records and total volume
could reach millions of items. Using reactivity limits, indexing, and WebWorkers, reduced heavy operations from 10-
15 seconds to 0.5-2.0 seconds and achieved 10x, and in some cases 15x, performance improvements.
