Technical Lead (React / React Native / Node.js – NestJS)

LenGreo is a full-cycle digital marketing & development company. We’re currently building a new social-media-driven platform — a creator–fan ecosystem similar in spirit to modern content-sharing networks, but with the ability for fans to support creators financially.

We’re at the very early stage of development and are looking for a Technical Lead who can define the technical vision and lead the build from the ground up.
 

Why this role matters
 

We’re designing a high-traffic, content-heavy mobile application. We need someone who understands how such platforms should be architected from day one — scalable, reliable, real-time, and optimized for fast iteration. Your decisions will shape how the product grows.
 

What you’ll do:

• Lead the architecture, technical strategy, and system design for the entire platform.
• Collaborate closely with our Business Analyst and Designer to plan the MVP, define system requirements, and create a realistic roadmap.
• Help validate business ideas and translate them into feasible, development-friendly technical solutions.
• Recommend the most suitable frameworks, third-party tools, and integrations to accelerate MVP development.
• Prepare accurate estimations and take responsibility for delivering within those estimations.
• Advise the team on a part-time / on-demand basis during the initial PBS & BA phase.
• Take ownership of the full development phase, guiding implementation and helping build out the tech team.
   

Required Expertise

• Strong experience with React and React Native.
• Backend expertise in Node.js + TypeScript, ideally with NestJS for structured, scalable architecture.
• Proven experience building platforms with social-media-style features: feeds, content posting, user interactions, notifications, real-time components.
• Deep understanding of integrating multiple payment providers for global audiences —
  including handling regional restrictions, fallback providers, and scenarios where specific gateways are unavailable in certain countries.
• Strong familiarity with third-party tools (chat, messaging, storage, content moderation, analytics, notifications, etc.) to speed up MVP development.
• Ability to design both MVP-friendly and long-term scalable architecture.
• Solid background in estimating projects, where you were responsible for both the estimation and the delivery.
• Ability to bridge business goals with technical capabilities, helping us simplify complex ideas without losing value.
   

Nice to Have

• Experience with high-load or large-scale distributed systems.
• Understanding of CDNs, caching, cloud infrastructure (AWS/GCP).
• Background in content-driven or creator-economy platforms.
• Knowledge of compliance nuances for user-generated content.
   

Engagement Format

• Initially part-time / consulting during project breakdown and planning.
• Expected to evolve into Development Lead for the full build.
• Flexible hours; long-term collaboration anticipated.

We look forward to hearing from you and hope we'll be able to build a lot of great products together!
